[QUOTE="DUCKMAN11, post: 3050963, member: 122313"] [USER=59541]@SteveBurton[/USER] Do you have a velocity goal in mind with the 156? Or are you just trying to get it going as fast as possible in a 20" barrel? More case doesn't necessarily mean more speed unless you have enough barrel/ bore volume to burn the powder from whatever particular case you decide on. The more overbore you go and the heavier the bullet the more temperamental things CAN get. I'm sure there are some 6.5-300wby's out there that shoot 1 hole 5 shot groups. But there are more 6.5x47 that do it. A 6.5x300prc is going to be a flame thrower in a 20" barrel. So if you are shooting suppressed, I hope you can clean your can easily. I'd look into a 6.5saum-6.5max sized case to do what you are talking about doing. [/QUOTE]
