richardca99, I’m getting 1490 mv presently with WW296, and could push it a bit faster. Looking forward to trying 4227, as it should give around 50 to 100 more than WW296.
That said, after I got my 400 grain mold, I did some reading/research that indicated that a 360 grain bullet may be the best of the heavier bullets!
At 100 yards from the bench using a Burris Fastfire dot scope, it will give 3”+/- , 4 shot groups. I have one cylinder charge hole that consistently opens the group up by 2+” 🤬 I figure that from shooting sticks, I should be good out to 150 yards on big game!
Good Luck with your 460. I love mine, just need to do more shooting with it! memtb
