Do you reload? If not I would look else where. I do not know much about the round specifically but do know its not something you are going to pickup at a local shop if you leave your ammo at home or mistakenly thought you had an extra box in the safe.
Are you talking about a .358 win which is just a necked-up .308?If so, I was on Grice's website the other day and it looks like they have some in Ruger American.I had a .338 federal built on Rem model 7 action and it's a pretty cool mid range hammer.
Yay or nay ?????
I doing some research looks like a great brush gun for deer and bear etc.
In the several tests I have read over the years a longer bullet does much better than a shorter stubby bullets. Think 160 gr. 6.5 bullet. Long for caliber. Outside of that I always liked the 358W. Pretty efficient. Considering limited capacity, even better the 35 Whelen.
