In my SBE and Extrema II they pattern like my Imods with 3" and a Mod when shooting 3 1/2".
These 12 Gauge stainless steel standard flush choke tubes are available in Cylinder, Improved Cylinder, Modified, Improved Modified and Full constriction. Not cheap at around $75 a tube but I'm thinking for what your describing the Patternmaster Long Range would make you very happy. Whether you are on the hunt for small woodland game, shooting clays, or out in the cold hunting waterfowl, we have the standard choke you desire. Its their theory and my results agree that you get more pellets on target sooner possibly decreasing cripples. There are slow motion videos out that show the Paytermasters to have shot strings of 2-3' long versus the 10+' of normal shot strings. The studs inside the tube are supposed to slightly retard the wad which keeps the shot pattern shorter/tighter in flight. When not hunting the "X" if you will with birds in my face I'm a fan of Patternmasters design. They come with 3 extended tubes that cover all needs and can be had for $75-80 shipped. Choose the widest possible choke for slugs.If you like this video, please press LIKE. The specially-designed longer choke tubes of the Crio System allows for more gradual. Always leave a choke in your barrel to protect the threads from damage. Much of the commercially available buckshot is made for hunting where grouping is a less valued attribute than power and production cost.I really like my Brileys and Pattermasters but truth be told for a do all set, the Carlson's Waterfowl sets for both my M1 and Extrema II pattern just as well. Benelli Crio M2/SBE II 20 Gauge Modified Flush Stainless Choke Tube. Ultimately we would recommend making your own as this is probably the only sure way to have a reliable supply with consistent quality. The only way to find out which buckshot cartridge works for your gun is to test every available type you can obtain, remembering that it needs to be continuously available or else you need to buy a lot of stock once you have determined which buckshot you want to use. It is important to point out that this result is not going to be possible with every buckshot variant you can buy, the ammunition used in the test was developed specifically for shooting IPSC buckshot stages in a process that took over 2 years! This spread enables 7 or 8 alphas per shot on an A4 IPSC target at 20 metres and well centred shots with a group this size will avoid penalties, even where edge to edge A4 penalty targets and scoring targets are alternated.
With the choke chosen we then proceeded out to 20 metres for a test to see how the group holds up. If you over choke buckshot the incompressible nature of the balls in the column will lead to flat spots being rubbed onto the outside edges of the balls and this will make flyers more likely. In situations where two chokes appear to give nearly identical results it is best to chose the more open of the two as less is more when it comes to buckshot choke choice. Our tests show the smallest group was achieved with half choke. The first thing to do is pattern the buckshot with each choke at the same distance, 12 metres is a good range to start the process as the pattern has some time to spread out: This is completely different to the flexibility of a wad full of tiny birdshot pellets which can be squeezed into a different shaped string. It is important to recognise that buckshot does not conform to choking in the same way as birdshot, this is because both the common configurations of buckshot – 8 ball (arranged 2x2x2x2 in the cartridge) and 9 ball (arranged 3x3x3 in the cartridge) – are incompressible as the outside of the balls creates a finite minimum diameter when the inside edges touch together. Extended chokes, chokes from different manufacturers, different barrel lengths and different gun makes are all among the variables that mean the only way to decide this is to test for yourself and you will need access to a full set of chokes for the test. The gun in the tests is a Benelli M2 with a 28″ barrel and the chokes are the standard Benelli flush fit tubes that were supplied with the gun when it was new. The gun in the tests is a Benelli M2 with a 28 barrel and the chokes are the. We are often asked for advice about the best choke for buckshot, the truth is that it has to be decided by testing and the results will vary between guns and chokes, here is the method we employed while developing the team’s 8 ball buffered buckshot. Do Benelli chokes fit 20 gauge Beretta / Benelli / Stoeger Mobil chokes. Deciding on the best choke for buckshot calls for some testing.
