Well a half hour into the season i took a bull moose with 168 gr vld over 73.5 gr. imr 4831,in a 300 wby mag. first time use with these bullets and i am absolutely amazed they are so accurate, i doubt i will ever use anything else i am that impressed with them, i was using barnes tsx's and these are cheaper and my gun likes them waaaaaay better. i managed to recover the bullet this morning and it nearly went right through, i had an angled shot that penetrated the neck , i recovered the jacket and lead core in the hide at the fourth rib from the front. Instant death!
