If this has been hashed before, I'm sorry...I am seriously considering a 6X45 build for yotes. I am looking for some help with barrel selection. The handful I have seen are either 9 or 10 twist barrels. I intend to shoot a 65 or 75 gn bullet. My question is will these bullets shoot well in fast twist barrels. Does anybody make a slower twist barrel? Anyone's first hand experience would be appreciated.
