I keep seeing controversial posts about alloys verse velocity along with variables like size, weight, hollow point. I'm looking to push a 160gn .402 diameter cast to about 1400fps give or take. It will be hollow point and I'd like decent weight retention. I'm not overly concerned with expansion but I am concerned with weight retention (I don't want it to fragment).
I'm also looking to run a 320ish grain .458 to between 1600-1800fps and same rules apply as above.
Can I use wheel weight alloy in both scenarios? May it be too hard for one or the other. Or should I just load some up and see how they do? I know plenty before me have done this or asked this question but I'd like to see if it's still a relevant concern with today's technology, alloys, standards.
