I have had success with 110 and 150g FMJBT with H110 and 4227, and 208g AMax with 4227. All cycled perfectly on my 10.5" with suppressor. I think 296 should work well also, but not sure of sufficient gas pressure with LilGun. Let us know what you find.

How is the speed with the 208s & 4227? Is is subsonic?

9" barrel, mainly use Lil' Gun with 168gr A-Max but have tried 150-180gr SSTs, Ive shot all loads out to 200 with decent groups. I use Trailboss and 208 A-Max bullets, not sure how fast but accurate to 50yds and quiet. Dont have a chrono

On an AR? Does the Trailboss with 208s cycle?

Well, here we are almost a year later, and I just loaded up my first 15 test rounds with 1680.
