I can vouch for the 52gr bucket mouth & the 52 gr speer match in a fast twist 223.
Both shoot tight groups, the Match is great for coyotes, maybe the perfect bullet for fur hunters.
The big mouth is fer blowing sciht up and shoots as good as the match, but lacks a little BC. Can be loaded to 3300
FPS easy, for both types. TNT's won't usually hold up in a fast twist 223 barrel, phfutt.

I would have got him too but a Dad Blam snow flake hit me in da eye....
