Well, I did not want to come back and bad mouth the 458. I now have more results, both good and bad. Nothing to brag about. Not complaining either.
I shot 300 gr Hornady HP with 56 gr RE-7. At 50 yards, 2.6" groups of 5 and 100 yards not even waste my time shooting 5 for a group. Bad.
Switched to 325gr FTX with 58 gr RE-7. AT 50 yards 6 shots under and inch (two sheets of paper). Moved out to 100 and got 3 into an acceptable 2" pattern. Considering using an old 3x Leupold heavy crosshair, not best for aiming at 100 yards. Good and appropriate scope for the gun. But not for shooting match accuracy. That was never the goal. Good.
The FTX have a reputation for breaking up on deer, which is fine, I hope to blow up some smaller critters.
I did not keep all the paper, but; since the forum is now hosting pics:
