I shot a ported 1895G and a non-ported 1895GS over a chronograph yesterday. I used factory Remington 405 grains so hopefully they would be more consistent than my reloads. I realize chamber size, barrel dimensions, how smooth the barrel is, and other things other than just the ports could have an effect on velocity, but on these two rifles the non=ported GS averaged 1085 fps and the ported G averaged 999 fps. Any of you ever have the opportunity to compare the non-ported and ported side by side? Just wondering if the ports are the main reason for the difference?
