After nearly finishing shooting at those silly coyotes using cast bullets from other CBA members, I am seriously considering getting some molds for rifles other than my 45-70. Reading results of matches in The Fouling Shot, and other posts here in the forum, gas checks hold their own in subject matter. However, I did not find any writings on how deep the seating of the checked bullet in the case affects bullets with gas checks (I may have just not seen the articles). Are there problems with gas checks staying on the bullet if the base of the bullet is down beyond the neck? How much do gas checks in the neck vs gas checks below the neck affect accuracy? Will a long bullet with a gas check below the neck have problems with the gas check staying on when the cartridge is fired? I am interested in what shooters experienced in this area have to say.
I have seen results of gas checks coming off bullets, but they were residing somewhere in the neck on the bullet before being launched. The barrel was not affected as the checks probably stayed with the base of the bullet until after coming out the barrel, but the checks sure marked up the chronograph (not my rifle, loads, nor chronograph; I was merely observing).
