boatanchor---your advice is much appreciated. I chose pac-nor because I have had larger rifles rebarreled by them with good results. Albeit never one with such high velocity. Is there another manufacturer that might be a better choice?
I was leaning towards 5 groove as a standard, what is the issue with 3 grooves and Amax in particular or any other bullet?
I know Hornady is using their ELD tipped bullet now because of issues melting and I'm assuming that also could be an issue at 3500-4000fps velocity.
