Quick has me beat on 45-70's, I've only got 3. Shikari, BC, and Shorty. Shorty is a standard 22 in. barrel, cut off to 18 in. I've got a Monte Carlo stock on it, with an old Shikari fore end on it. I turned a 12 mm bolt to the configuration of a sling stud and epoxied it into the ramrod channel, with the stud part sticking out straight in front. Truly handy, especially in a box stand. Shorty killed 5 deer last year, using 300 gr. Hornady FPHP bullets, loaded to the top of the trapdoor levels. I shot one big 8 pointer, quartering away, at about 60 yds. Went in about the last rib on the left side, exited about halfway up the neck on the right. Hit 2 ribs going in, clipped the spine, 2 ribs going out. About 27 inches of penetration, hit bones, and still exited. You don't have to step on a 45-70 too hard to achieve results. And it doesn't pound you while it does it's thing. With this rig, I don't really see much accuracy difference in the way I hold the gun, or rest it. I did bed the fore end to the barrel with epoxy, and it is pretty stiff due to the large barrel dia. and short length.
