Brownbear, I to worked for a Taxidermist for over 15 years, I miss it, but not the job to have if you love to hunt. I think I have the right BP rifle. It is a .54 38" one in 60 twist. With 90 grns. BP I believe if I can keep my shots to under 100 yards, I feel I will do well. As far as the range and whitetails, I can pretty much keep 5 RB within a dollar piece at 75 yds, shooting stix , not off hand. Not bragging and believe me that is nothing to brag about, I have seen others shoot, and they are incredible.
Aim small, miss small that is my attitude and has really tightned my groups.
Thanks again, and the home work begins to find a good hunt with some credibilty and hopefully someone of knowledge and understanding of BP.
