Late 7x57 FN ammo was likely loaded much hotter than the rounds designed for these rifles! Venezuelan contract probably for large ring Mausers and FN49s. Plenty hot! ~2900fps w/ a 139gr bullet, IIRC. SWAG 50,000psi or more chamber pressure- rather more than the original loads.

Right you are, that Venezuelan contract ammo was too hot. Put some 140 grain Federal Power-Shok thru the rifle yesterday, ran fine. Thanks all for comments and advice, Don
