Yes, John, you've posted it. But that's o.k. The only reason I remember is because of the reference to the Ron Smith gain twist barrel. One of my teammates had one screwed onto an original Meacham Highwall action done up in French Grey, and chambered in .45-2.6". We traded wins at the 1,000 yard line at Fort Lewis for years (I think I got the better of him in the long run...), me shooting my C. Sharps Model 74 in the same chambering. We both shot the 540 grain Paul Jones Creedmoor, but he seated his way out with three grease grooves showing and about 110 grains of powder. I seated mine deep with no grease grooves out and only about 80 grains of powder. He shot backrest and had the sight on the heel of the stock, while I shot prone with the sight in the standard location on the tang. I think his gain twist was much more aggressive, though, like a 3:1, ending one in 18" at the muzzle.
Pretty rifle. You can post it again in awhile, if you want...
