Finally got around to working up my 100 grn Acme HiTec bullets. I plan to test them at the range in a few days. It’s my first time reloading a cast lead bullet. All my reloading up to this point has been using jacketed or copper plated bullets. So, I bought the Lyman Cast Bullet Handbook to find load data and went to work. Max load with Red Dot is 2.0grn, so I made a few with 1.7, 1.9, and 2.1 grn. Although 2.1 is slightly over max, my OAL is a little longer than the Lyman load. If the 1.9 grn load feels adequate at the range, I’ll stop there.
Some observations- very narrow load range from min to max. Also, the max load is much smaller than my 100 grain jacketed loads I had been using (2.0 lead vs. 3.1 FMJ).
My question is whether the maximum powder charge with cast lead is based more on keeping velocity under a certain point rather than reaching the maximum SAAMI pressure limit.View media item 2552
