Sierra has a 180gr bullet that measures .311 if you think that might work for you.Ah dang, Im hoping to find some .310 bullets. I was thinking that the x54r was the same diameter.
I have a box of remington clean bore bronze tipped x54r laying around that I have no use for, Brass case I am pretty sure. Could be yours for $15?
And I'd love to buy that box from you. Just shoot me a PM and we can figure out where to meet. I'm in Norman and thinking of going to Bass Pro in OKC sometime this week if that helps.
