I appreciate it. I think a longer barreled 223 bolt action will be my next purchase with the intent of shoot 75gr elds, 77gr smks and some of the 80gr stuff. Probably going with a factory tikka for now unless I can source some parts for a deal (not planning on that haha).I was merely using those loads as an example. I agree with you, there is no need to run loads like that in a 18"-barreled gas gun. In any event, the H4895 and N140 powders you have should still both be excellent choices in your setup.
