So I am getting a gift card from BPI due to the Paramont muzzleloader recall and I'm looking at getting a new rifle. I decided on the model Bergara B14 Sierra and between a 6.5prc and 7prc. I do have every other cartridge they offer in the line up, so there's not a "need" to it. Most closely I have a 6.5 Creedmoor, 280AI and 7mm Rem mag. what should I go with? I built my 7Rem mag for heavy bullets on a 1-8 twist, and I have a lot of 6.5PRC once fired brass.... What say you
