Many times there are posts here about aperture sight accuracy and other posts about the use of gas checks. Like most days, I was out shooting today, with leverguns using Williams and Skinner peep sights out at 100yds. Group size made more of an impact then I would have thought, which is where the gas checks come in. I have identical LBT molds for a .430 280gr. LFN bullet, one is gas check and the other is not, other then that the bullets are the same. Both were loaded with the same heavy charge of H-110 powder(Max.). The gas check bullets averaged 1-1 1/2" grps., the plain base groups opened up to 3" or so, based on this I'd have to say that you can't just say that they(peeps) will shoot 1 MOA if the ammo won't group that small. The 400 grain Hollow point Gc in the 45/70 was pushed along at 1900fps and grouped around 11/2" at 100 with the Williams peep and Firesight front. I don't believe my results would have been any different if these rifles had scopes on them, and that's why I favor the rear peep sights and firesight front sights and gas checks on my serious hunting bullets.
