I'm assuming you want an sbr in 6.5. I don't have one so I can't say specifically but that's quite a bit of powder to burn in a short span. You would probably end up with quite the flash and very loud. My 6.5 is a 24 inch so the sound isn't bad but my 11.5 inch 556 is pretty loud. I did just finish a 8.5 inch in 300 blackout which has full powder burn in the barrel and isn't too loud with subsonics. Just my opinion but I think an sbr 6.5 isn't an efficient use of the cartridge. But then again I own dumber and less efficient guns just because I wanted too. Either way at least you get to have another gun.
