Title: Re: 30/40 Krag reloading?

I finally "worked up" my 220 gn load. From Lyman's data, previous chronograph readings for my 180 gn load, and QuickLoad pressure and fps estimates (which are inaccurate at these pressures, but help gauge barrel length changes), I started at 35.0 gn of 4895 (with Remington 9.5 primers) and got fps readings both sides of the desired 2000 fps in my 30" barrel. Thus ends my "working up," until I run out of this bottle of 4895. Pressures should be 31000 to 32000, which makes me feel better--it is just a rolling block. I wouldn't call it a squeaky clean burn, but it's clean enough.

I found interesting the 220 is a relatively mild recoiling load. My butt stock is done in an older style, with the end grain mildly checkered and no plate or pad. My boney teenager was whimpering about the recoil, but I found it quite tolerable. My previous 180 gn load is a bit sharper in recoil, probably because higher speeds mean a shorter thus more abrupt recoil. Compared to the 180, the 220 is in the direction of shove and away from sharp, not that either load is a prime example of shove or sharp.

My rifle is only 6-3/4 lb, and original fps is all I'll care for. It's a grand old cartridge. I was a bit worried to see Remington and Winchester brass supplies dry up, but others have stepped in to the market (at a higher price). I think it's a keeper.

Next up: A reduced recoil 125 gn load for my boney teenager.
