Hi All,
First post here. I've been researching the 450 Bushmaster, as I'm thinking about building an AR (out of mostly spare parts) for this cartridge. It would be a 16"+ barrel suppressed with an adjustable gas block (I have multiple buffer weights, but hopefully my Armaspec SRS suffices). My question has to do with barrel twist rate. Some sites recommend the 1:16 twist rate for subs: ~400+ gr. BHW only offers 1:18 twist.
Is there anyone out there who could provide real world testing data on shooting subs from a BHW 1:18 twist barrel (preferably 16" barrel) and what their MOA/MRAD grouping is?

Thank you in advance for any input!
