I use the Sierra 69 SMK, and if the wind is up and the range long, the 75 gr Hornady BTHP both over Varget.
If the velocity is up and the range short the expansion is good, almost too good. If the velocity is down and the range long the expansion is less or very little at all.
The jackets are probably too thin and separate at close range and aren't bona fide hunting bullets for most people.
I love 'em for problem yotes that the farmer, his son, the neighbor and his son and son's friends have taught all there is to know about game calls and suppressing fire. lol
