If a
longer barreled smoothbore, say ~44” & over, I have seen a marked improvement in consistency by switching to 1Fg powdah. Using my big 75-cal Dutch ‘Hudson Valley’ fowler of 60” barrel, I took 2nd place in a woodwalk (18-targets) where I only missed the 15 & 20-yard animal gongs (shot over them) and didn’t split the 3/8” wood dowel in half
.
But, I hit all the other chains or gongs out to 80-yards and whilst using a 90-grn 1Fg load, I shot well over 30-shots that day without wiping the bore between shots.
FWIW I find that a vege fiber wad cut in 1/2, lubed & seated below the patched/lubed ball, gives my smoothies the best accuracy at 50-yds, as in 3” groups or better (benched). But I also do load development for each load, starting at # of grains = bore caliber & working my way UP in 5-grain increments.
My experience ... smoothies shoot better w/ higher powdah charges! Oh and whilst using that 1Fg load ... the recoil is negligible, whereas 90-grns+ 2Fg charges wasn’t fun for more than a few shots.
My current goal is to create a traditional ‘paper cartridge’ load that gives me 3-4” groups or
better at 50-yards.
