so as mentioned in previous post, i have a saami spec 7mm rem mag. new nosler brass. loaded up for a ladder test. the mild loads grew by .022 and the higher end loads grew a a little more. i've only loaded for 3 other guns, a 308 and 2 different 6.5 saums so i am wondering if this is normal? my 6.5 saums don't grow at all it seems. anyway, i will do the usual headspace check and probably wind up bumping the shoulders the usual .002-.003. but is there something special about these 7 rem mags? thanks
