Been doing some load and alloy testing lately.
Rifle is a rebarrel 112 Savage in a heavy BR type stock. It wears a 30 inch Krieger barrel. Cartridge is a short 06. Cases are formed from new Hornady brass as I have a bunch of them. Chamber is tight necked at .337 so I have to turn the necks.
Case capacity is roughly midway between a 308 and an 06.
The goal is to see what sort of accuracy can be obtained while pushing the velocity envelope with cast. I'm not after the smallest group possible but rather the smallest possible group at velocities over 2500 fps.
A few weeks back I discovered the max pressure, at least with RE17, and my water dropped range scrap. Today I will be shooting HT range scrap, heated to 450 for an hour then quenched, but with RE19. Will the slower powder and slightly harder bullets prevent the shotgun patterns as pressure rises?
I am also looking at same charges of RE17 but with a different alloy, Lyman 2. In the future those charges will be fired with an alloy of 1.6% each Sn/Sb. I need to make up another low tin but higher antimony alloy and then add some tin to that too.
I want to get a personal handle on how alloy and powder burn rate interact. Gonna take a bunch of time and shooting but isn't that why I'm here?
