What length should I chop this barrel to?

What length to chop my 6.5 PRC?

Had a 23" suppressed on a bear hunt in oak brush a few years back. No interest in repeating that. I decided to hunt that one unsuppressed and all others are going 16.5-18" threaded. So much handier.
 
Well, the smith measured it up and it doesn’t look like I’ll get shorter than 21” or so if he goes .740 at the shoulder. Damn heavy ass Bergara contours. I left him with my suppressor, so he’s going to measure that up and get it as short as he can. If I recall correctly, they said on the podcast that the OG6.5 can actually fit shoulders slightly over .750, so I’m hoping he at least gets it to 20”. I wasn’t interested in doing a custom contour to cut an extra 2”. We shall see what he does in a couple weeks.

If I recall the discussion correctly, it will fit up to .780 ish if the bore is perfectly centered in the barrel. That's the part that creates issues and necessitates the safety margin.

That’s right! Well fingers crossed because we were at .760 at 18”. But I bet he’ll cut it between 20 and 21 and call it good.
