Uh-Oh Bad Bore on the Remington 721 300 H&H

[browningautorifle]

Just need to watch the auctions.

I already looked, you'll find one. I only found one in 300 Win.

I countered bored it 1/4" with a 3/8" rotary bur in my hand drill. Made all the difference. Yours being 1/2" would be a lathe job.

Yours ideally would be done with a special drill bit too.
