I've got a stack of these small rifle primers; the white boxed gold small no 41 primers commonly used by Ar15 reloaders concerned with the floating bolt pin. Has anyone had success using them in 6.5x47 Lapua? I know these were designed with really thick cups. It seems the cci 450 is the goto for this cartridge but is there any truth to these no41 primers being the same as a 450? I know load development will tell the true story but i dont want to waste time priming with these if they aren't as conducive to accuracy as 450's or federal matxh.
