Steve, i don't think you were using the right powder if all you could get was 4025fps😂
I did have the hairs tilt once while i was shooting a 30-06 with them saboted 55g 22's. Hand loaded of course! None of those pokey factory rounds for me.
4250 fps. Ground squirrels vaporized. Until i couldnt hit em. Sent the scope back to baush and lomb. They returned it in a week. Note with it said "tilt, you may want to check your loads!"
Maybe you want some saboted 223 55grainers? Or maybe a mdl 70 with a frozen bolt?😄😄

the consolidation of the states into one vast republic, sure to be aggressive abroad and despotic at home, will be the certain precursor of that ruin which has overwhelmed all those that have preceded. Robert E Lee
