Once again tried some stuff in .45-70, and had a pleasant surprise.
Few days before I'd found a small jar in the garage that was full of 230-grain roundnose bullets, sized .450, for .45acp. Which made me think(sometimes a dangerous thing), and I cast some more: some sized to .452, some left as-cast. All got the three-wrap paper patch with onionskin, then a wipe with lube and through the .459 sizer, then loaded to 2.54" overall over the same ten grains of Green Dot I've been using with the 255-grain semi-wadcutters. Results, all at 50 yards off a solid rest.
Bullet sized .450"
Bullet sized .452"
Further experiment: took some of the 255-grain SWC bullets on which the sides were flawed(hadn't filled-out completely when cast*), I was curious if this would have much affect on accuracy, or if they'd still do reasonably well. Same distance, over the same 10.0 Green Dot:
With perfect(within reason) sides
With flawed sides
And, just to see how they'd shoot, some of the .255 cast of pure lead
Reason for that test was something that came up once before using full-power loads with a 405-grain bullet. Found that it shot that bullet with no patch, just lube in the grooves, quite well, but the same bullet of pure lead gave much wider group. However, put that same bullet in a paper patch, and it works quite well. Same thing with this rifle.
Lubed bullet, crimped in first lube groove, over 26.0 of A5744, 100 yards
Patched pure-lead bullet, same load and range,
See why I like it?
One last thing I tried: 100 yards, three of the 255-grain loads, left hand resting on the front rest:
By the time I finished this, put my stuff away, and scrounged for brass for a few minutes, I was about ready to melt.
*Not flawed all over, mostly there'd be a place along one side where this happened.
