Finally had a chance to get to the range, albeit if just for a few minutes.
Rifle used was a 22” LaRue Ultimate Upper build, TBAC 30p-1 suppressor.
The first group (Target 9) included the clean cold bore. I then switched to the 140smk on Target 8. I probably should have fouled the barrel when swapping targets, but it is what it is. I followed up with 1 more group of the 140smk’s on target 3.
Mt daughter tried her hand with the large frame gasser on Target 6, but wasn’t able to drive it as well as she can a 223/5.56.
Take aways: based on limited testing, both rounds are very precise, especially at their price point. The 140smk rds cycled better in this particular build than the 140bthp’s. I noticed 2 stove pipes when my daughter was shooter her group. This build doesn’t have an adjustable gas block, so it could have been the ammo/suppressor combo that caused an issue.
The 140smk’s felt a bit hotter on the recoil impulse, and ran flawlessly.
I’ll definitely be grabbing more of this to feed my large frame gassers.
