just starting out

[huntndakota]

I just purchased a 10" TC 300 whisper barrel, 4 boxs 221 unfired brass, and the RCBS 3 die set from a coworker(it was her husbands who died) for $150 I have searched for info for the 10" barrel and couldn't find any specific info for it. My question is does anybody shoot this and what is their experince with it for game animals (deer,groundhogs)? And could i shoot the factory ammo out of it just to get started shooting it until i have time to load my own?
