viewtopic.php?f=5&t=16122"What a timely post.
I just finished loading some of these 225gr Magtech schp in my 450 bm.
These are my results...
38.0 to 42.2 gr of Lilgun in .3 gr incriments.....average mv for 3 shot groups.
Hornady, once fired, brass, Federal 205 primers, brass trim 1.690", COL 2.150", Ruger American Ranch 16" barrel.
38.0. 2442 fps
38.3. 2454 fps
38.6. 2443 fps
38.9. 2436 fps
39.2 2493 fps
39.5. 2495 fps
39.8. 2500 fps
40.1. 2507 fps
40.4. 2550 fps
40.7. 2446 fps
41.0. 2476 fps
41.3. 2516 fps
41.6. 2508 fps
41.9. 2556 fps
42.2. 2568 fps
Accuracy wasn't all that impressive, most groups, at 100 yds, were in the 1.5 to 2 moa range, although several expanded past 3 moa.
However, the 39.5 gr load gave me a solid 1 moa group, with 2 shots on top of each other.
A little more work, tinkering, may improve those a bit."
I may have been on the losing side, but, I'm not convinced it was the wrong side.
