RE: new moose gun help?
30-06 does work well on moose, i know this from experience not hearsay... You DO need to use heavy bullets and that means 200 grain not 220's... I by far prefer NP's...
7 Rem. mag. also does a great job, and you need to feed it 175 grain bullets for best performance on moose.. Once again i'd use NP's and it also is fine on big bears with that load...
Everything above that is just more of the same, (with more recoil) but you do need to use heavier bullets in each case to get good penetration and also to "break" a bear down if you go bear hunting.
