    i use the fx chrono the speeds and ft1lbs will be different if you do not weigh the pellets so you have a batch that are the same weight then your speed and ft1lbs will be very close

    Because I'm back on airguns after many decades, would it be fair to say by 'close' you mean consistent?

    Hi, Ive just used the micrometre a cartridge and its just over 70mm in total . They fit lovely. The box says 3" but min chamber 73mm. On the barrel it says 76.2 I can post pictures. The dealer said it was 3" chambers and I even said are you sure, he looked again and confirmed. 

    Don't forget that the given length of a cartridge refers to its open (fired) length.

    Hello, All the info on 410 side by sides the 77mm cartridges would need a 3 inch chamber, The AYA 410 i am sure is 2 3/4 inch, You may need to consider a different shotgun rather than your AYA

    I thought that the cartridges were 73mm. Although I KNOW not, with a proof requirement of 850 would these be a 70mm designate as per a 67.5mm 65mm 12 bore?

  4. For some reason for your last post what is now above, 'lets see what......with' did not appear on my screen, but is there now. No, I don't think that it makes sense as for all intents and purposes one bar equates to one kg/square cm

  5. Please don't act on this for the reason given earlier. However, it looks as though you have a albeit slightly undersize 3" chambered gun proofed at 1100 whatsits and also some either slightly oversized or undersized I know not which 70mm or 76mm cartridges which require a gun proofed at 850 different whatsits. My earlier request remains valid, but I believe the 850 would indicate a non magnum proof requirement.

    Well before I can convert I need to know what the 1100KGs means?? Theres no conversion I can find for straight KGs to Bars!!! Here we go down the rabbit hole lol.  

    KGs is a weight - can be confusing because - Italy for example - some countries mark the barrels with their weight. Try Kgs/square cm. One bar equals 1.01972 Kgs/ square cm - so, like for like in practice. I'm avoiding answering your original question as I know nothing about 410s not having shot one for some 70 years.

    s200 .22 i use 16 twist  right hand twist for the B.C. in my scope

    Is that ballistic calculator or Ballistic Coefficient?

  8. I keep a half decent pair of Bushnell stashed in the car for serious looking but for a quick shufti I have half a pair in a dash cubby-hole. I don't know what's current, but back along if you found a decent pair in a charity shop there was usually something wrong with them: so one looked until you found a pair for which the defect did not affect the central focusing or the half secured to it and bought them. A quick hacksaw job and a nice little Zeiss 'monocular' which takes up no room and cost all of a £5er does the job nicely.

    25% varnish.............75% thinners.................or recommended thinner..ask your chandler

    when you varish wood for marine purpose.....you cut it back 75%...then 50%.......25%......then full fat varnish with a sable brush...sanding down between each coat

    if you cut it back 75% and put it on really dry wood ...it will dissapear...just suck it right in....slop it on a few times (plus the ends) and the wood will be well protected

    use exterior marine varnish as it will have UV additives in it...

    you wont need the full fat varnish its a outside bench after all...just stick to cutback and let it soak it and dry between eack coat

    Brilliant! Thank you very much indeed. :thanks:

    get some decent marine varnish....and cut it back by 75% and slop it on...let it dry and do it again.............

    Cheers. I asked because I haven't a clue. However, we have a chandlers so that's sorted but what on earth is, "cut it back by 75%, please?

    What would be really helpful would be for the manufacturer to label how long the wad/ case takes to biodegrade in the environment they are used in 

    What chance is there of that when although there will be a shot size number given on the packaging what size that physically is is anyone's guess. :mad:

  12. Some advice, please, Guys. 

    I have just bought a garden bench seat which is flat pack and has already been pressure treated. Before it arrives in a couple of days could anyone kindly advise me on a quality brush on treatment which I would use annually - starting now before assembly - which hopefully will provide another layer of protection.

    Hi ,thanks going to try and get the pulsar ballistic calculator  on my scope but asked  for the ballistic profile of the pellet saying which G profile is the pellet G__ havent  a clue is it G1 or others just tried looking on H&N site but tells you everything  but what this is H&N 18.13 in .22 pellets would be great if you could find it thank you 

    I'm getting the deja vu feeling that we've been here before way back. It boiled down to a difference in terminology. In my ignorance I don't even know if airgun pellets have a G number. I'm afraid I can't remember the specific details now but have got a feeling that what the programme/calculator was asking for was actually the BC but was termed something like the form factor which it was decided had given a nonsensical answer. Using the BC put things right.

    If you wish, give me your velocity, zero range and sight height for the pellet I'll run Infinity so you can compare things - my leaving the same BC for the same velocity boundary will make very little difference.

  14. This is a guess and not a particularly educated one at that. Is 'G' also known as the 'Form Factor'? If so, then the answer is 1.38.

    If it helps, what info are you after as I can run it through my Sierra Suite programme which permits me to enter the BC of choice?

    It was a good score, especially with tight chokes, well done.

    Some of the top skeet shots use tight chokes for training to make their shooting more accurate - then revert to skeet chokes for comps. I had the pleasure of shooting with some top skeet men a couple of years ago - team GB etc. Boy they could shoot! They were training with full chokes and the clays were disappearing in a puff of smoke. Impressive. I missed a couple - they didn’t. That’s the difference between a club shot like me and someone at their level. I appreciate this has little to do with the OPs topic, but interesting to get people’s views. Ramble ends. 

    No matter, 3 pages in and the PO's topic has been well covered; besides you've made some good and very valid points in your various posts. Shooting was already changing from that of the 19th and early 20th centuries when in the mid 1900s along came NTS and the various studies into its effectiveness. These revealed that in addition to the information they were looking for, historical ideas needed changing as whereas previously the majority of 'targets' engaged were at a range where little or no choke was required and as a consequence even if it was given any consideration it only applied to the ranges in vogue. As we're shooting a scatter gun, a 100% success rate is not ballistically possible so in order to be reasonably successful with the longer range shooting now more common, multi chokes for a varied quarry/range one gun man have their advantages. I mean, who would have ever thought that 1&1/4 oz of No 3 shot would have ever been considered essential for pheasant. :oops:

    one of the key roles of a PCC is to hold the force’s Chief Constable to account for service delivery.

    That's to say, Wymberley's example could put the PCC in really poor light,

    The  reason that my example would put the lady in a bad light has nothing to do with me; by failing to reply to emails which detailed a valid cause for concern regarding a poor service delivery performance she has managed this all by herself.

    Yes Conor I did, - unfortunately Hernandez was re-elected on a 22% turn out. 
    Can you tell me her plans for improving firearms licensing, and hopefully avoiding another event like Keyham ? I believe one of her responsibilities is to hold the chief constable to account for the running of his force.

    Good post! :good:

    We'll have to wait and see. It seems that the good lady has won over some BASC staff and also the NGO firearms chappie. It is reported that the firearms dep't had received no training in some 20 years. As she's been in post for 8 years, one could well ask just what has she been doing in all that time. 17 weeks for grants and renewals? There's a well known HMFs' expression for things of this nature, Had it not been for a switched on MP, my straightforward plus one variation would have taken heaven knows how much longer than the actual 25 weeks that it did.

    Yes, I did.
