Drake, I know that there are external differences between the different revisions of Pmags.

Are there differences between the INTERNAL dimensions on new and older Pmags.  It seems that the older Pmags could be loaded with a round of longer COAL than the latest edition Pmags.  

Is this just something that I am making up or is there an actual difference in MAX COAL from older Pmags to newer Pmags?

Internal dimensions are virtually identical but in either case the max C.O.A.L. is 2.260".

Virtually .... hmmm

Reason I am asking is Ive found that my rifle likes the heavier bullets seated out further and closer to the lands of the barrel and with newer Pmags they dont seem to feed, but in an older pmag they will feed fine.
