Looking to buy a long range barrel for my next build. I want to shoot the 80g A-Max at 1.06" long seated to 2.40. I am torn between the McGowen 26" 1:8 Wylde chamber or the 1:7 .223 chamber. I know the 1:7 will certainly stabilize the uber long 80 Hornady bullet but I'm not sure if the .223 reamer used will allow the higher pressure loading the 80 to 2800FPS I'm looking for. I know the Wilde chamber will but will 1:8 spin the 80 sufficiently. I emailed MCGowen and they don't know or have any experience with this bullet at all.
