RE: Bullet Manufactor?
Your best bet is to try some different loads in your gun and see what shoots good. If your just going for deer you don't need the more expensive stuff but it sure looks cool.
Most folks I know all really like the Winchester Supreme ammo. Personally I reload all my stuff so I haven't purchased any factory stuff in a long time. Just remember you don't need the lastest and greatest super bonded 40$ a box stuff. Tons of deer have been killed just as dead with good ol' Remingtion Green box stuff.
