PRS Talk Best 3D Printed "stuff" you've tried?

While waiting for MDT to release the productized version of Francis Colon's thumb rest, designed/printed one for myself for M-LOK chassis, and for things like the Foundation Samson. Got a couple friends running them, too. Will eventually buy MDT's when they get around to releasing them (to support the guy with the original idea), but until they, they work great. Printed them in PLA and in PETG - haven't ventured into more temp sensitive materials, yet, cause I don't have an enclosure at this point.

12” 308 chamber & twist recommendations

I’ve got a SBR’d CDG & a Nighstalker waiting on a barrel. I think I’ve settled on a 12” 308 and will primarily shoot 110-125s but would also like to shoot some subs.
Was thinking a 1-10 should be fine but why not go 1-8 twist and would you pick a different chamber for shorter bullets since subs can be loaded deeper in the case?

Thanks for the help
10 Twist and shoot 155 supers and 185 Jug subs.

If you go lighter on the supers you will be extra loud, no meaningful increase to velocity and expect to hit transonic 20% faster.

Lightly used Botnia Maxi 6.5 muzzle brake (5/8x24).

Asking $525 shipped CONUS.

New these are $770

Watch reviews on YouTube. These are the best brakes on the market. 70% recoil reduction on mid-size calibers and 80+ % recoil reduction on Magnums. It really is insane what these brakes do.

12” 308 chamber & twist recommendations

I found that even a 1:10 twist on an 18" barrel didn't stabilize boat tail subs. Shot the flat base sierra round nose 180-200+ grain bullets.

My guess is that if you shoot those you will be fine regardless.

A 1:8 may have more wind drift between supers/subs to account for. Similar to the issue with a 1:5 300Blk vs a 1:7. That being said, a 1:7 twist 300Blk doesn't have wind "spin" drift so you may be fine with a 1:8.

Not much of an answer, but bullet selection may be your friend.

Green and black MDT Field Stock for right hand bolt. Short action. REM 700 footprint (will fit clones)
