Messing with a sporterized Krag I recently acquired. I've been shooting up some 311284s I found a can of in my dad's stuff, I'm pretty sure a friend of his cast them and they are hard, no idea what the alloy is.
I shot up the last little bit of IMR4198. I'm kind of stingy with my stash of SR4759, which worked pretty well too. Shot some with 23 grains of 5744 today and they are plenty accurate enough for hunting. I'll eventually cast some of my own 311284s with soft noses for that purpose.
I'm thinking of increasing the charge a grain at a time and seeing if/where accuracy starts to drop off. The Lyman manual says you can go up to 28 grains, but I don't know. I'm guessing 23 gives 1500 FPS, which oughta do the job with a bullet that heavy. It's not giving and signs of pressure, but it recoils more than I'd have guessed and sure doesn't seem like a wimpy load.
Any thoughts? I really like this old rifle, someone did a good job sporterizing it and with the receiver sight and good trigger pull it has, it should make a fin hunting rifle.
