Thanks toeverone that offered adviceearlier last week onthis sitefor BP loads and using patched Roundball's with my Flintlock. I'm now shooting my T/C "Firestorm" with 175 grain patched RB's with .015 lubed pillow ticking and doing much better at the range.I have it narrowed down to 60-70 grains of a 50/50 mixture of 2f & 4F Goex BP down the barrel because I couldn't get 3f.I'm using 4f in the pan. The gun seems to love this combination of powder and fires so much faster. No more pifffffffff-boom now it's Piff- Boom! My accuracy has gone way up but I ran into one variable.

Can wind have a big effect on the flight of a RB? I had a direct crosswind coming from right to left at the range about10-15 knots at 50 yards. Istarted to noticemy RB shot's were hitting more and more to the right on the target.... I was going to startmoving the rear site but thought I better not touch it, I was shooting fine earlier in the day until the wind picked up.

I also have an old box of 50 Buffalo Bullet Company MAXI BALL-ET's 270 Grain lubed with what looks like bore butter (like my pillow ticking patches).Isthis a good bullet to use for Whitetail with my T/C Firestorm with 1/48" twist and BP? If so, any idea how much more Goex BP I would have to use to push this bullet since it weighs 100 grains more?

It also seems I can only shoot about 70 yards max because the sites on this gun are terrible. At 100 yards you would just about block out a deer aiming with these sites. Does anyone know if there is a better rear site available then the large fiber optic one T/C has on it? Seems like all their custom sites are for their other guns. Like to put a peep site on it. PA doesn't allow scopes in the primitive arms season.

Appreciate any and all information.
