Most manuals give an OAL of 2.47 for this bullet.My rifle will not accept anything over 2.445". I'm not crimping for this rifle but the bullet is very deeply seated. Is this typical of 760's or did I get a freak?I shined a light down the muzzle and looked at the throat through the ejection port.The leade of the rifling looks as though it has no angle to it or a very sharp one.Round noses and bullets without much full caliber length above the groove chamber fine at an OAl of 2.525. Any thoughts apperciated.
If it's any consolation, I have a Model 700 in 7mm Exp Rem from about that time (Jan. '80) that's a bit short-throated......or at least it's very particular about which bullet shape and loading depth I can load into it without hitting the lands/grooves. My Model 725 in .280 Rem isn't nearly as particular.
I think you'll need to scrutinize which bullets you load and be mindful of the individual particularities (shapes) of each. The other option is to find a gunsmith who could lengthen the chamber/throat area, but that could get expensive.
