I'm new to this forum, but not new to smoke poles. Been at it since '76. Killed a number of Bambis, Yogis and Wapiti with TC rifles. I wonder why it's taken me so long to find this Forum, it's certainly a great recource, and you folks have certainly taught an "Old Dog" some new tricks. I shoot a Tennessee long rifle that I built from a Track Kit. It has proven to be a real tack driver, and I must say that some of the info I've gleaned from the contributors here, has enhanced my appreciation of the sport. This Tennessee is a Pecussion,42" GW Barrel, 1:70 twist.It will shoot a .490"cast PRB (.015 cotton patch, lubed lightly with Mink Oil),over a fiber wad, or wasp nest material, ahead of 50 gr.2F black Goex powder, into a 5" gong, offhand at 50 yds all day, If, of course, I do my part. (Sometimes my part ain't adequate). I have found that Mink oil patch lube is less intrusive than some of the denser patch lubes and leaves a slightly cleaner bore. I swab with a denatured alcohol patch between shots to produce consistant accuracy. I have also experimented with 3F, Triple 7,( 3F T7, lights off better than 2F T7) and using the same 50 gr. charge, and load combo, I get even better velocity and impact approx 1" higher at the same range. I still swab between shots with denatured alcohol and find the bore considerably cleaner than BP.
I've used a load of 90gr Triple 7, fiber wad and a 250 gr. R.E.A.L.cast bullet, lubed with Mink oil, at 100 yards, shooting over crossed sticks, and have been able to consistantly hit an 8" gong (of course, if I miss, it's undoubtedly my fault. I've found that most rifles shoot better than I do).The R.E.A.L bullet is about the same length as a RB and gives good accuracy in the slow twist barrel. Great combo. Incidently, with all above target loads, I run a clean dry patch down the barrel, after loading, to clean any grease and fouling from the barrel forward of the load, before firing. This seems to produce greater accuracy.Just ramblings of an "Old Dog". I hope it helps.
