bench test of big slow boolits with crongraph

[Gerald C]

] I finally got to test my pc tumble, black powder boolits over my Ohler35, I shot 10 rounds of naked but lubed boolits,I broke them into 2 groups
of 5 each, group 1: random seated. group 2: indexed boolit seated. then I cleaned the rifle started with clean bore and shot 9 more shots with the boolits tumbled pc, first group was 5, second group was four. ( don't ask what happen to # 5, never got loaded ) these were all shot at 100yds,
over a bench rest. the boolits are 547 grs. 16 to 1 alloy, rifle is a Stevens 44 1/2 45/90 34in. barrel. I shoot long range gong for some years, this gun has always shows some leading but not enough to be a problem




first photo naked boolits random seated



2 photo indexed




3 photo pc random seated



4 photo pc indexed



the pc boolits showed 16 fps faster, groups about the same, I had no leading when I cleaned the barrel. I'm old and I don't see very well but I think I'll be using pc boolits in the next match.
