[QUOTE="Dr. Vette, post: 2443058, member: 22335"] I prepared two 300 Wby Mark V stainless rifles for a moose hunt last year. One was 26" plus muzzle brake, the other 26" with Mag-Na- ports. Those don't have as many holes as the OP's ported rifle, but you get the idea. Both shoot the same 180TTSX load at 3210 fps. Zero difference, repeatedly. I suspect that differences in barrels may cause more variation in fps than the porting vs muzzle brake in the case of my two rifles. In the end, I surely would not cut down the barrel of the ported one because I was worried about velocity loss. [/QUOTE]
