Did some testing with Remington 11-87 auto and 870 pump 28" interchoke shotguns, with Winchester 00 buckshot. Looking for max effective range for goats & pigs.
Improved Cylinder (1/4) was OK at 25 yd but Modified (1/2) held the pattern to 30 yd.
Full choke had noticeably heavier recoil and terrible blown patterns.
Since then I just use Modified for buckshot and pretty much all other lead shot sizes.
