I'm real close to your load for my main dogtown fodder. I'm off to SD 8-11 June with about 1200+ rounds of ammo. This is 2 days shooting with 2 shooters. I loaded mostly 50 grn V-maxes, some Blitz Kings, & a few SPSX, & 'dogtown' types. I did my own limited cleanliness testing, which was looking through the bore after a similar number of shots. I compared the old standby H335 & TAC & found the TAC much cleaner. Last summer in SD I noticed the AR action getting fairly dirty after a good number of H335 rounds were fired. A quick field cleaning got the son back in action.
