I have a Husqvarna with a 28" sporter barrel, sporterized forearm. I refinished the gun, and slow rust browned it all, redid the stocks and added a peep sight. It shoots good with Unique, and I consider ok with about any task I ask of it, but cant get the question of how good will it shoot with holy black, having shot many a round of 45/70 with black and easily held MOA out to 400 yds. Since the 12.7 is basically a 50/70 short, or a 50/60 I thought I would ask for any good shooting loads before I started experimenting. I have been shooting a Lee 464 grain made for the S&W .500, made out of soft lead or wheel weights, with the bullet touching the rifling. I cant help but think that a compressed load of 2ffg with a veg fiber wad underneath it would have to shoot very good. The barrel is bright and shiny, good deep lands and grooves, a few very small pits that don't seem to affect accuracy. All feedback welcome!
I am in a Rehab right now from surgery, hip removal, will be going home in a week with a plastic spacer and about 6 weeks later have a new hip put in, have been fighting infection for over a year now and this is the only thing that will work.
