Suggestions wanted for x54r crown angle

6500rpm · 12-15-2011, 09:16 PM

Starting on a x54r heavy barrel Mosin project. As some of you may know these aren't exactly plug and play and they absolutely butchered the business end of the barrel. What's the prefered crown degree to use on a 7.62x54r barrel (barrel length is going to end up in the 22"-23" range shooting heavy ball).

I have been told by numerous tack driver enthusiast a 11 degree target crown and 21 3/4 on the barrel is the sweet spots.Dragon slayer should know for sure and can confirm hopefully.

Thanks bud, at this point you two are my go to guys at this point. Really have enjoyed reading your build up info.
You (or anyone for that matter) haven't seen any listings for a carbide x54r ruffing chamber reamer by chance? All I've found seem to be HSS finish reamers at this point. Just looking at options if needed.
