What a beautiful day at the range today! About 3 inches of snow and around 30 degrees...... Well.. maybe not the best day to go shoot, but what the heck.
Today was the first day I shot cast from my .300 weatherby. Special thanks to David R. and Kenjuudo for suppling me with boolits to shoot.
Powder of choice was IMR 4831 and I started at 40 grains, and worked up to 50 grains. 4 lots, a 40 grain, 45 grain, 47 grain, and 50 grain. Shooting a boolit around 180 grain (311291).
It's a scoped rifle which is setup for shooting roughly 3,200 FPS and I knew I wouldnt be anywhere near this, so I thought I would fire these off at 50 yards and see where they go. I'll give a conclusion after the pics.

40 grain was somewhat speratic. I only chronyed one that came out at 1,703 FPS.

45 grain I think is where i'm going to work around, split a couple holes there, chronyed two at 1929 FPS and 1844 FPS.

47 grain did alright Chronyed 4 at 2001 FPS, 1909 FPS, 1889 FPS, and 1922 FPS

50 grain.. not too great. Chronyed 5 at 2,096 FPS 2033 FPS 2050 FPS 2100FPS and 2043 FPS.
Overall it shot much better then I expected. I've never shot cast out of a rifle so this was really new to me and it seemed to do really good. I'm going to work around 45 grains and see if I can lower the grouping more.
I'm also going to heat things up a bit with these bad boys. I've heard pushing cast at 2,700 FPS is around max? So I'm going to be loading up some higher grain rounds and see if I can get around that barrier :twisted: ...
Enjoy.
