I stand by my statement that motorways are the most dangerous place,statistics are skewed because more people drive off motorways than on,so you cannot have a like for like comparison,here are a few facts. Also 90% of motorway accidents are driver error.
"There were the following accidents on Major roads 1,818 fatal, 13,284 serious, 88,399 slight on Motorways, A(M) and A roads."
Source: National Statistics publication produced by Trabsport Statistics: DfT
"Current statistics indicate that …. more than 1,500 people are killed or injured each year on the hard shoulder."

Can't agree with that Welsh - In 2008 there were only 158 people killed on the whole Motorways in the UK, this is just 6% of the total 2,500 road deaths that year. In that year there were 869 serious injuries on the Motorway compared with 26,000 serious injuries overall.I stand by my statement that motorways are the most dangerous place,statistics are skewed because more people drive off motorways than on,so you cannot have a like for like comparison,here are a few facts.

Since 2008 the numbers have continued to fall. As all part of the smoke and mirrors of usual government figures, the presentation by County Road safety Officers to groups like Speed Awareness courses and Driver Improvement courses are encouraged to use the KIS figure (Killed/seriously injured) which sounds much more dramatic than deaths.

Just as an "add on" can you guys give me some an estimate of the average number of lessons, you think, it now takes to pass a driving test - I know you all only took 8 hours, but I'm talking about someone starting from scratch with no practice at home?
Can you tell be how long you think the driving test is now?
Can you tell me about what percentage of tests taken are passes?
Can you guess how much the driving test fee to apply for a test is now?
I think the average guy in the street is has lost touch with how the driving test has changed over the years.

I have found Eley subs to well down of the stated 1065 fps - More like 990-1020 fps, that's with my 16" and my 20" barrel rifles. However there does seem to be something wrong to give you your excessive drop. If the rifle has a moderator I would remove it and shoot another group and try and shoot a few of your rounds through a chronograph.

Ahh yes. That's the basic idea - Here's the diagram I drew for another forum. I made this tracker in 2011 and put the video up then but kept it private until a few weeks ago.
These are the type of panel I used to drive the positioning motor:

and this is the type of motor.

For this prototype I used plastic gears from a cheap salad spinner.

Using the same panels and a similar motor my second version carried a 40lb payload with no problems. -
The issue for 3rd world countries is that they cannot afford much, I am sure you know all this. I was involved with a project to TRY to make solar cookers for under $1. We did a folding cardboard shape to be "like" a parabolic mirror (had a number of small flats really) and with your film on it. It sort of worked but could not track the sun.
So you piqued my attention with your tracker....
I know very basic technology is the answer - It's either got to be bullet proof and never need any maintenance or so basic the local bike mechanic can fix it.
I recently read a report about using a rope pump to lift water from deep wells - a really basic idea that works well and was made locally. The well and the pumps were provided by charity but after a year only about 10% were still working - disappointing really.
I would think a solar cooker would work well in the equatorial region without much tracking being necessary - a simple solar concentrator as you mentioned can easily and quite quickly raise a cooking pot to boiling temperature - Then you could use the "hay box" method of slow cooking by just folding up your solar cooker that doubles as a well insulated box and leave it to stew for several hours.
-
There are several uses for the tracker and solar cooking would be an ideal use. - many undeveloped countries have plenty of sunshine but often are short of clean water and cooking fuel. A very simple tracker similar to this mean you could add a cast iron cooking pot and it would boil away all day (Mmmm! Goat stew:))
My longer term thoughts are that you could boil and condense water on a continual basis. If you had a small header tank feeding a flash boiler,maybe nothing more than a tight coil of smallbore copper tube. Collect the steam and condense it by feeding the steam pipe back through the header tank, you would get pure fresh water run out the pipe.
Dirty water in - clean water out.
No, I'm not an engineer, just a life long tinkerer. I'll do a video of how the tracker works, it's very simple with no electronics or computers involved.
Here's a bit more of my tinkering: If you click the subscribe button on my videos you will get notification when I post up more.

Thought you guys might be interested in my homemade solar tracker - This is just lashed together out of wood to test the idea. I works perfectly so I'll get started on a more substantial version to carry a PV or maybe a hot water panel.
Using a tracker to keep a panel facing the sun increases the efficiency by more than 30%

Yes, sure it's a 1/16 but the easy way to check is to remove the bolt and insert a cleaning rod with a patch about half the way up the barrel. Make a mark on the top of the cleaning rod at the breech end with a felt tip marker, then slowly withdraw the rod until you can see your mark has completed one full turn, then make another mark on the rod and measure the distance between the two marks.

I sent a PM to him a couple of days ago but so far no reply.

Here's a short video comparing six different types of subsonic ammunition, including Eley HP subs, at 65 yards in typical field conditions (windy)

Not sure if this is common knowledge, but prvi brass is exactly the same as lapua and 1 or 2 others. Its just stamped different "prvi" "lapua" etc. Got this first hand from the owner of Henry Crank when he was up here for a Roe a month or 2 ago.
There may be some truth in this rumour - I've noticed they look very similar, they are both brass and they both have a big hole at one end and a little tiny one at the other. Got to be true hasn't it?
-
I use PRVI 100grn soft points on foxes, and they do make a mess!
Just an observation :My Howa .243 1500 with a 1/10 barrel shot the PRIVI 90's fairly ok but the 100's were a waste of time with nothing like an acceptable group, much happier with bullets in the 85gn range.

Well there's a story:
CLANDILLON, JAMES ALBERT
Rank:Flying Officer
Trade:Pilot
Service No:117778
Date of Death:18/02/1943
Age:28
Regiment/Service:Royal Air Force Volunteer Reserve
Grave Reference Sec. D. Grave 4344.
Cemetery LITTLEHAMPTON CEMETERY
Additional Information: Son of James Papillion Clandillon and of Dorothy Florence Clandillon (nee Robinson); husband of Betty Eleanor Clandillon, of Ilford, Essex.
Extracts below from the RAF Ford Operations Record Book:
19th February 1943.
F/O Clandillon was today killed in a Beaufighter crash. The Beaufighter was F.I.U. His Observer F/O Griffith baled out and landed safely.
23rd February 1943.
The funeral of F/O Clandillon took place today at Littlehampton, attended by the Station Commander, W/Cdr. Maxwell MC., DFC., AFC., the Station Adjutant F/Lt. Jackson, Squadron Commander W/Cdr Chisholm DFC., his Flight Commander and brother officers. Full Military honours were accorded and a number of relatives were present.
Extracts below from the Fighter Interception Unit ORB:
18th Feb 1943.
NIGHT. F/O Clandillon (F/O Griffiths) took off on patrol. After some vectors from Blackgang they obtained a contact at 6 miles and closed in. The next thing known is that the target fired at the Beau. The Beau opened fire and continued to fire until his cannons jammed. He damaged his quarry but unfortunately his quarry damaged him. Both oil pressures fell to zero. One engine packed up. He turned for land and warned the ground he might have to bale out. Finally the other engine went and the pilot instructed F/O Griffiths to bale out. This he did and safely landed close to Gosport aerodrome. The pilot stayed in the machine and crash landed nearby. The Operator was little more than 1,000 ft. when he was ordered to leave the aircraft and this left little time for the pilot to jump. In the crash the pilot unfortunately lost his life. -
I really can't see the point - If you have a bolt rifle then sticking it on a sandbag and bore-sighting will get you pretty near, all you need is for the first shot to get you on the paper, then you're home and dry.
Here's a short video of how to easily zero your scope. I shot this with my phone camera so not the highest quality.

Well I never lol
Any reports of downed planes in the area ?
This is another interesting point - where did it come from. It's obviously not been fired, it's not loaded in it's case, the case would be brass so not disintegrated, the rounds would have come from an ordinance factory so were not "homeloaded" at some Army/Raf base. It's definitely military and really quite unusual I would think - certainly something a collector of these things would be interested in.
Maybe more clues on the sight or a bit of local history digging required. Could there be some Home-guard connection?

When I read this thread I also concluded that it was not a bullet and when I read the comment by 1066 about incendiary devices I thought "here we go again". Now am am feeling rather silly for being so arrogant and will take a large slice of humble pie with my morning coffee. There is always so much to learn.....
No humble pie required. The depth and history of our sport/hobby is vast, whether from the sporting, military or historical perspective. Nobody can begin to know it all, we can all continue to learn if interested in the subject.

Yep, found it - don't unscrew it. Look half way down this page.
.303 B Mk VI incendiary (Dixon/De Wilde)

Here's the gen.

That's interesting - Looks like it's not been fired but I would be a bit wary of unscrewing the screw before I'd done a little more research - Could it be some sort of incendiary or explosive round. Can you clean it up a bit and measure the calibre?

Looks like the Hatsan 1000 is also marketed as a Winchester 1000 and a Daisy 1000, you might have more luck searching for triggers for a daisy than a hatsan.

Pretty straight forward job for a tinkerer - When you have pulled twenty different ones apart you'll get the idea. Have a look through these images and see if there is something similar.
Maybe something like this
and might find something here:
http://www.pyramydair.com/blog/tag/beeman-r7/
I would say the long leg of the spring runs down the back of the trigger to form the return spring. One of the pins will fit through the eye of the spring and the short leg of the spring must have somewhere to anchor it, probably behind one of the other pins.
How about showing us some more pictures of the complete trigger unit.
Quick tip - Take some pictures with your phone camera before pulling it all apart.
-
I have one and found it to be very consistent even if just strait dumping.
but really fine powder will leak from around the drum. It may be that mine is a bit worn.
It's not a lot but still quite annoying
If you take it apart and clean it out, when you put it back together again you can adjust the clearance of the cones by varying the tension on the centre bolt holding it together.

I use a Lee perfect measure also, although I never load straight from the measure, always dump and trickle. However, if I was a straight dumper then I think the Lee is as accurate as any of them. I have a fancy Ohaus measure and it's no more accurate than the Lee. The Lee does tend to have a smallish hopper so if you're dropping 50 grains or more a time you will only get around 50 rounds before you need to top-up.
Here's a really interesting article by Laurie Holland comparing measures - The Lee came out better than some of the really up-market ones.

I noticed my sights were out today and when checking them I realised they were loose on the mounts, I'm now struggling to line them back up. Can anyone advise me on how to do this properly as it was done for me before and never used scopes until recently.
If you're new to scopes and worried about re-zeroing you might find this short video useful - For some reason, if you view it on a phone or tablet you don't get any captions come up.
-
sure the ones i had came in a see through plastic container with seperate compartments as you describe, but could be wrong, it was a long time ago
You're right mate the early ones did come in a clear plastic box - just the same as the black box shown above. I still have some.
If the idea has merit, and I think it does, then rather than think they were **** because of the poor accuracy, the product just wanted more development. Just think, if the chap who made the first .22 rimfire more than 150 years ago gave up because he only managed a 2" group at 25 yards.
Sabot rounds are used to good effect with centrefire calibres and I can't find any legal reason why they should be banned, if they were to be used in rifles capable of producing more than 12ftlbs then they would simply become FAC rated.
Should the Driving test include Motorway Driving?
in Off Topic
Posted
As I said in a previous post - the average guy is now out of touch with the current driving test. Dual carriageway and national speed limit roads are included in the test if possible, and of course, driving at 70mph would be expected by the examiner if appropriate.
The length of the driving test was increased several years ago especially to include dual carriageway (70mph) driving. Now 85% of all test centres are able to include these higher speed reads on the test.
