I've been working up a 405gr RCBS FN-GC bullet with H322.
Lyman tops out at 48.5gr at 27,100 CUP. 1740fps from a 24" barrel.
John Taffin runs the same bullet (I think) with 52.0gr. I guess this based on the idea that modern lever actions can handle 40K psi loads. I'm not that brave.
I assumed my load of 49.0gr would clock around 1600-1650fps from an 18.5" barrel. Boy was I wrong.
10 shots, 15 feet from unit, approx 60 deg.
1801, 1823, 1849, 1841, 1844
1826, 1836, 1828, 1841, 1811
High: 1849
Low: 1801
Average: 1830
E.S. : 48
S.D. : 15
Then I decided to use the last 10 for a very lazy accuracy test, and ring some steel. But after I hung the 4" gong and retreated 70 yards or so to my shooting position, I thought maybe it fell down before I got back. It took the 4x magnification of my range finder, and a good look to solidify in my mind where the steel was is reference to the burned trees. I really need to paint that thing.
I only hit it once. I need to stop expecting so much of myself from field positions. But I did some major damage to the two trees in line behind the target.
The amazing thing though, was when I did connect with it that one time. I had the target hung with paracord, and the whole rig spun around a good half a dozen times. It made a good dent in the AR500. And somehow the coating on the quick links got removed and deposited on the cord itself. Amazing.
Certainly powerful enough for the bear load I intended. Though I may just have to go to a 100 yard range to confirm accuracy.
