I have used the following Hawk bullets with perfect results.
In my 450.400 3 1/4" double rifle the .025jkt, 300 gr has taken a deer and several wild pigs. All have been drop to the shot kills. About 50% have given complete penetration. The bullets I recovered where as 500 grains said "coined out".
BIG mushroom, no bullet shank.

I have killed one pig with my 450/400 and the 400 gr .035jkt. It expanded well, but had decent shank left. It was a quartering shot on a running pig.

In my 9,3x74R a 285 gr Hawk with the .035jkt has taken a few deer, a few Impala, a baboon, and several wild pigs. All but one have been drop to the shot kills. One pig ran about 20 feet. Recovered bullets were the size of a quarter with a good shank left.

I have been really pleased with the performance of Hawk bullets in my guns.
Velocity with the 300 gr 400's is 2330fps, the 400 gr 400's @2100fps and the 9,3's 285's @ 2250fps.

I repeat, ALL have been drop to the shot kills, except one pig that ran about 20 feet.

You cannot get any better than that IMHO.
