Put some rounds through the MkIV, the RRA Poly and the Kimber Stainless Target II in 9mm. All three guns are stone cold reliable and accurate to a fault.
Mostly using the Kimber for testing some handloads. I was trying to find the best OAL for the handload I am using currently, which is 4.6gr of Power Pistol and a 147gr SNS bullet seated to 1.110.
It's shorter than I'd have thought, and surprising to me because the federal 147gr AE which all my 9mms shoot exceptionally, is about 1.130. Maybe because power pistol burns fairly quickly...
Anyways, mission accomplished I believe. This gun was nowhere near this accurate for a while until I got a new Kart bushing installed. This target was fired when I found the correct OAL node, and was fired offhand at 20 yards.
