Hey 720,
You replied to my post last summer. The additional testing i did with Enforcer yielded ES at around 250fps (several times) and all my brass has been Starline. So i am seeing odd results like you. I have since moved to H110 at a charge of 16.3gr. I’m at 1170 fps out of my 6” Patrolman but ES is still high at 174. However, all charges were dropped and not individually weighed. This bullet remains a challenge. For now and even with a high ES with both Enforcer and H110 the loads do what i want them to. I would like to understand why the ES is so high though. GRT wasnt that helpful with Enforcer but i have yet to run H110 through it.
