  1. Geolander A\T on my 4x4 Duster for last 7 years, wouldn't have anything else, on my 3rd set and last about 30,000 miles per set. Not full mud pluggers, but a go anywhere tyre as good on road, tracks, grass and snow as you can get for a multipurpose tyre and mostly used in 2wd as 4x4 only required when it gets really tricky.
  2. It doesn't make sense but as noted by the OP, all the 30 and 32g loads seem to be no5's, with no6 being restricted to 28g..... The "choice" is a heavier no5 load with a pattern that becomes less than optimal even with full choke at 45 yards or a lighter no6 load that the pattern goes to less than optimal also at 45 yards, but not the heavier load and no6 which with full choke would stretch to 50 yards.... you do wonder what manufacturers are thinking.....
  3. I would respectfully disagree, whilst you are correct with the shooters, there are a significant number of cartridges from different brands which are sub standard in one important respect. Shot! I have two issues, both of which are of terminal importance when shooting. All cartridges should be sold with the shot size claimed, in either pellets per Oz or size in millimetres, so that everyone understands what exactly they are buying. loading a British cartridge with 2.8mm and calling it a no6 with 25% less pellets in the load means patterns fail before they should do leading to wounded and pricked birds. All cartridges should be sold with shot having a crush value above the cartridge chamber pressure i.e. an Antimony level giving protection to the shot above the cartridge pressure as there are far too many manufacturers selling cartridges with the cartridge pressure on firing exceeding the crush level of the lead shot, again leading to blown and open patterns, a lot of game cartridges are made with 2% antimony, when in reality they require 3% at a minimum and 5% in high pressure magnum loads. When the above two faults are combined, you end up with loads that noticeably do not pattern well and cause a lot of pricked birds or chipped clays. Sometimes it is inconsistant shooting but other times it can be the cartridge, it's not that they don't go bang reliably or kill within 35 yards within which 90% of shots are taken, but due to the faults above rapidly decline in performance past that even though they are often sold with the promise of being hard hitting (translation oversize pellets) but which sacrifice pattern and therefore overall range to achieve this mostly at the cost of wounded and pricked birds.
  4. Flight was based on observable evidence in the same medium (i.e. the air) and an understanding of physics and airflow. Fusion is trying to replicate a process based in the solar core without the 1000's of atmospheres pressure required by substituting increased temperature and without understanding how the sun at it's core actually functions as they cannot observe/measure the conditions inside the sun, nevermind duplicate the process.
  5. They are using 3% antimony shot (tempered) in a cartridge operating at pressures that require 5% antimony (supertempered) to prevent damage to the shot which results in open patterns.
  6. The reason they are very quiet about it is that it doesn't really work on Earth, other than for a few seconds and even then the energy output achieved compared with the energy used to get it working is not even break even and is stil in realms of scifi. The best yet I believe is Chinese where they managed just over 100 seconds, but energy in was greater than energy out. Effectively the sun core teperature is 15million Kelvin (or Celcius doesn't really matter at this scale), but to get a tokomak to work on earth you need to get the plasma up to 150million kelvin as there is no extreme of pressure available. The suns core pressure also means that the Hydrogen in the core is in its metallic form (has formed a lattice structure) whereas we are experimenting on earth with plasma (gas with electrons stripped from it) which further makes matters difficult.
  7. No 6 fails in energy at 50 yards, No5 at 60 yards where both are about 1ftlb. Maximum range in therefore governed by which cartridge/choke combination can put a minimum of 120 pellets (i prefer 150) in a 30 inch circle and still meet the minimum energy requirement. It will be interesting to see your results and see what the maximum ranges end up as, especially if you are shooting a 20b as most of my testing is either 410 or 12b. Most Shooting magazines tend to gloss over some facts which contribute to some longer range 'kills', the most important being the no of pricked birds which are not killed dead in the air but instead killed on impact with ground or wounded and picked by dogs. They also tend to gloss over a lot (but not all) of the so called high bird shooters have custom guns, which between longer chokes, longer forcing cones etc can add a couple yards to any cartridges range over an off the shelf gun but still does not justify the extreme ranges at which some shoot, but is an advantage.
  8. I know it is unwise to get too hung up with chokes but the correct or incorrect choke selection can have a significant impact on your shooting. - Only at the extremes.... IC and LM will deal with anything out to 40 and 45 yards respectively with a 28g no7 or 32g no 6. Having spent some time in discussion with Teague and considerable research of my own, it is clear that 12 and 20 gauge do perform differently with different choke combinations. - No they dn't if the chokes are producing 60% pattern at 40 yards (both with mod choke) they are doing the same however you might meed 20 thou choke on the 12b but only 16 thou on 20b to get same result due to the smaller bore. A 20 gauge inherently will have a longer length of shot in the cartridge, consequently it will hold a tighter pattern for a longer distance over a 12 gauge. - No it doesn't, due to compresion of shot often the pattern is wider due to more damage shot caused by higher pressure of longer shot column. However there is no available data I could find for this. The heavier the load the more open choke is required to preserve the pattern. - Only at the extreme of shot column length, effectively the excess pressure blows pattern due to more damage to pellets but you can also have choke blowing the pattern if too much compression too quickly at muzzle. I have been thinking I have been under gunned on some days but apparently not. For example a 28gram cartridge 20G will maintain a better pattern at the longest ranges through 1/2 and 3/4 than anything else, whereas a 32g 20g will give optimum performance through 1/4 and 1/2. - Depends on the cartridge and only at the margins - for instance my 410 with 21g loads will print best pattern with a Light Mod Choke, after that, more choke gives worse pattern due to blowing up pattern at muzzle and 410 has longer shot column than 20b. I plan to get on the pattern plate finally tomorrow to test the data, using a suitable number of shots of course to be statistically accurate. - Worthwhile, take photos and run up from Cyl to full for each and work out what gives most shot in 30 inch circle and best distributed, both my LM and Mod choke give same numbers in 30 inch circle but the LM gives the best distribution. Really interested on what is required to achieve the 3 hits on bird for a humane dispatch. - 6 pellets required to give 3 in vital areas. I could post my findings if others are interested.
  9. 3 inch would be most versatile for your intended use. 3 inch will generally cycle 2.5, 2.75 and 3 inch without any issues and 36g of No1 Steel will drop geese to 50 yards. 3.5 inch wil be generally be less able to cycle the lower power shorter rounds (2.5 especially due to gas bypassing the wad) possibly giving issues in reliability. The availability and price of 3.5 inch cartridges is also an issue.
  10. But they couldn't make steel shot as cheap as the Chinese... The issue though isn't really the cost of the steel shot (currently about same the price of lead shot as whilst iron is 10 times less expensive than lead, but manufacturing costs 10 times more) but also the cost of the non plastic wads which is partly caused by manufacturing costs but is also due to patents and licencing.
  11. My Franch Alcione Sporter OU's are a composed pair, serial numbers are 82 apart, bought the second as a spare but available for double gun days if needed.
  12. In the Europe most people have trouble recognising a threat as in general areas are safe and they are not expecting it, seeeing a threat and reacting to it are two different things. If he was visiting different areas, due to the silence of a bow, most people would be withing 20 yards before they recognised a bow, and probably shot by the time they started to react to it. 20lbs draw weight with broadhead arrows will go through a man ribs at 20 yards and pass through the heart/lungs and lodge in rear ribs/spine. lars is talented and demonstrates what can be done, but using a bow is not unduly difficult.
