rockets are great heads but i think anything over 1.5" is too big. they dont penetrate that well on deer. i would go down to the sidewinder it has a better tip anyway. the only thing ive have seen that makes them good heads is bad shots. my brother has shot about 4-6 deer in the stomach while using those. they all dies within 100yds. it just cuts such a big hole the guts just fall out. i shot one deer at 8yds with that head (tried it out 1st time) it came out the other side but didnt pass through completly. but the deer only ran about 30 yds. unless your not confident in being really accurate id go smaller. better penetration esp. on bone.
