I cast my first batch of bullets for my 45 Bisley yesterday using old wheel weights. I loaded three batches, with Titegroup at 7 grains for about 900 fps, 8 grains for 1000 fps and 10 grains for about 1200. (Chronographed)
The two lighter loads performed well, and shot a decent group at 50 yards.
The fastest loads surprised the heck outta me! I shot a group at 50 yards ( 6 shots) and then fired two into a box filled with dry newspaper at about 20 feet. To my surprise, both bullets went in sideways! When I recovered the bullets, there was almost no sign of rifling marks on the bullets.
I also fired a lighter load ( 1000 fps) into the box, and in penetrated about six inches, and showed rifling marks.
What do I need to do Go to a harder alloy for the faster loads?
Thanks for any advice. I will try to post a picture of the recovered bullets.
The bullet that went straight in ( 1000 fps) is on the right. The two bullets that entered sideways are on the right.
