6 PRC reloading

[406Backwoods]

I have an extra 6 Creed barrel that I wanna get punched out to a PRC. It’s a 7 twist though and 26” which worries me that a lot of bullets won’t make it to the target. Anyone have words of encouragement?

I would not do it. You will be around 330,000 RPM. It might be okay but also very likely not. That 6 Creed must be already getting great speed out of a 26”. With your RPMs already exceeding 300k so that’s already marginal and would scare me, especially suppressed.

I know it’s what you already have but there’s no reason I know of that anybody should ever be running a 7 twist 6mm. 7.5-8 is the sweet spot and you even see in the Hornady manual that they use a test barrel for 6creed has 7.7 twist.

Unfortunately 7 twist was my only option with the barrel. Haven’t had any issues yet but the added velocity of the PRC makes me wonder what bullets would survive the journey. Monos aside
