I recently bought an accurate mold for my .44 mag. 430-280g. plain base.
http://www.accuratemolds.com/bullet_...bullet=43-280G
I want to develop a mid range load for targets and critters out to about 50 yds. The suitable powders I have on hand are;
TiteGroup, Longshot, A2400, surplus bulk BR-5, (for which Unique data is recommended.)
I would like to get into the 900-1100fps range. I'm not finding much printed data for the 280. The Lyman manuals seem to jump from 265 gr to 300grs, and everything else I find listed is for those copper things. I've loaded a few starting load rounds with 2400 and longshot so far, just to cure the itchy finger/new mold syndrome, but now it's time to get serious with the development.
Anyone willing to share their experience with, or, recommend some load ladders using the listed powders and give me some direction?
Thanks in advance.
Dave.
