Re: 7 mm STW barrel length ?
I have always read or heard that for every inch of barrel, you can either increase or decrease velocity by 30-50fps. I was hoping to get a 28" for my 300 RUM and shoot the 200g at 3300fps. That might be pushing it, but you can get a tad over 3200fps with Retumbo and 26" I figure with the extra 2 inches, maybe 3300fps is attainable. I want a brake on my next barrel, or rifle. I dont want a 30" with 2" brake, thats to long IMO. I would like a 28" with a brake.
