I'm shooting a striker in 270 wsm with the factory brake. If I swap out a 16 inch barrel in place of the factory 12 inch(+2" brake), will my gain in muzzle velocity be much better? Ernie had told me to subtract 375 when working in the g7 program for the 12 inch barrel. I'm trying to get my ballistics for the 16 inch.
thanks for the reply. I was just surfing the net and came across a couple articles about it. I was figuring around 80 to 100. Although negligible, it does answer my question. Thanks again for the response.
