Its a PITA...but if it shoots that good with that combo...I'd say leave it alone, and just clean it after every range session/match day. Takes 15-20 minutes?
You can burn up a good barrel, trying to make it do what you wanna do (or at least I have). That looks to be a very solid grouping load/gun, especially if you get that to repeat over multiple test sessions.
I agree with you.
That load is lights out when its on point. So if it turns out the barrel just doesn't like to shoot dirty and I need to keep it scrubbed, then I'll keep it scrubbed.
