Maybe because the 77's are BT's ???
I was wondering why the Sierra book doesn't have any info for 77SMK for bolt rifles, but it does for gas guns. Any one know what is up with that?
Most likely, the 77gr SMK max is lower because it can be loaded to mag length (2.260") which reduced case capacity and increases pressure. The 80gr SMK can't be loaded to make which increases case capacity, so you can put more powder behind it and get the same or lower pressure than with the 77gr SMK.Quote:
