I have an older M700 BDL in .308 Win I'm thinking of changing up. So keeping it .308 caliber or smaller to continue working with my .30 cal suppressor, what would you do? It's a constant 1.5" shooter with me behind the trigger for five shots.

I bought as a barreled action with a factory barrel sporter contour currently cut to 18" and threaded. I added a TT Primary trigger to it, and a Greyboe Trekker stock. Hunted it, it's about was about 10 lbs all up with mountain sling, Omega 300 suppressor, NF 3-10X42 SHV, Warne MT pic rail and rings, plus five rounds. I'd like to keep it the same weight or a little less.

I'm open to most ideas for cartridges, but I'm kind of stuck between .308 and .22 Creedmoor. I'm thinking of adding M5 Hunter bottom metal as well.
