ORIGINAL: 700xcr
I too have a Rem 721 in 300 H&H that I inherated from my dad when he passed away. My brother-in-law lost or got away with alot of 300 H&H brass. I my have 100rds. Dad load was H4831 with 180gr. Remington bronze point bullets and it is veary accurate. Back to the subject. I don't see anything wrong with the Rem 721.
Is 300 H&H brass hard to find? I seen 2 boxes of the loaded ammo today in faded boxes.
