Re: Using PB projectiles designed for PP, as GC non PP

The pointed bullet is the Schmitzer bullet Lyman #457658DV - designed for long range shooting, with a BC in the .4's. It is amazingly accurate at 506gr. in my alloy, just as the Lyman RN #457125, is amazingly accurate. They shoot virtually identically in my 18" twist 35" GM barrel's Sharps.

A week ago, I was out at the range with a friend who was getting his Rolling Block ready for rendezvous this coming week. His last loads tested came together - 60gr. 2f GOEX (.100" compression), wax-paper disk, 1/8" SPG lube wad, wax paper disk, 525gr. RN(#457125) (30:1), the bullet lubed with SPG as well.

2 consecutive groups off the bags at 100 meters - both were 1.5" centre to centre - shot dirty - no blowing between shots. ALL the fouling pushed out the bore with one dry patch. Len has an inexpensive tang sight coupled with an inexpensive Lyman aperture front.

Note the large capacity square grease grooves on both bullets designed specifically for shooting black powder. Of course, they work well with smokeless powders as well, but usually require an un-side-down gas check (cup-down on powder) or a 1/10" hard card wad for it's base protection.

The pointed bullets (& RN's) shoot 1" to 1.5" in my own Sharps (apertures), loaded identically to the above load listed, except I use Swiss 1 1/2F powder now. I used to use GOEX with the same accuracy results at 100 meters, however the shot to shot strings are closer with Swiss powder, thus the long range accuracy has the potential to be much improved.
