With the 6.75” barrel, is there ammunition that would reach effective terminal velocities? Very interesting.
The 55 and 62 grain Gold Dot / Fusion loads should work nicely.
According to these threads, they expand down to ~1700 fps.

Damn Clint.
Dammit.
Your original 16" Optimum LW barrel has basically invalidated all my 16" middies...and I've sold them all because the 16" BRT Opt soundly outperforms all of them for my mixed use (50/50 can/no-can) when all factors are considered (weight, accuracy, recoil pulse, gas system function with suppressor). And I only ever owned properly gassed barrels from BCM, LMT, and Faxon (most recently). Even my agency supervisor, an accomplished shooter and experienced LEO, was immediately impressed at the soft recoil impulse despite my gun's light weight and using just a BE Meyers ASR flash hider mount. He kept commenting on how smooth the recoil pulse was for such a lightweight gun.
But the 9" PDW is fascinating.
And so is the slightly heavier 16" med-con continuous taper barrel.
Ugh.

I'd love to spin Pappabear's 338 Titanium sig can on one of the 11.5s.

Clint-How is the contrast between the MPR and SPR barrel in a suppressed, LW scoped role? Have you had a chance to test the MPR on paper? I'm tempted to look at the MPR over the SPR due to the barrel steel and subzero temperatures we see here.
What is the Velocity with M193 and M855 in the 6P? I was Looking at getting a 12.5 barrel because I have 3 10.5 SBRs, and kind of want the extra inch. Also why 5/8x24 threads?
