We free floated my buddies and retorqued all the screws. I believe we went 3-5lbs over what was recommended. He is shooting the load I previously posted and his shoots bugholes all day long. Any specific recommendations for cleaning/removing the carbon ring?

Hi Coues: The carbon ring can be very hard to remove if left too long. I used a product called TM bore cleaner that seemed to work well and it can be left to work in the barrel. I would avoid amonia based cleaners if possible. TM was developed by a BR guy. If corbon persists, use lloso paste or JB bore paste only if necessary. I have used straight Alcohol but this method MUST be followed by a light coat of oil,as this method dries the bore down to bare metal. A quality barrel should not need this method though. Nearly all shooters think of copper build-up is all that needs to be addressed. Carbon is a barrel and accuracy killer. Hope this helps you. ......SEMPER FI!
Shot some of my test loads. Just 4. I originally loaded 6 at 50 grains and 6 at 51 grains of 4831SC. Of each 6, 2 were loaded at. 3.00" (.02 off the lands), 2 at 2.98", and 2 at 2.95". I started with the 50 grains at 2.98" which shot about 1-1/8'' group. I noticed the primers were just begining to flatten at 50 grains but no stickyness in the bolt. I keep hearing about .04 to .075 off the lands so the next group I shot was the 50 grains at 2.95" and they shot awesome. I measured the group with my digital calipers at .23" center to center on the bullet holes.
I'll pull the 51 grain loads since the 50's started to flatten primers and load some more 50 grain loads at 2.94, 2.95, and 2.96". I think a 3 shot group of each will do. I'll keep you posted. Maybe if weather permits I'll shoot these tomorrow.
No I haven't tried any other powders. Stuff is so hard to get right now. I have two pounds of 4831SC. And I know a lot of people have good results with this caliber with it.
Gave it a good cleaning and loaded 3 rounds each at 2.94, 2.95, 2.96". All at 50 grains. My book list 50.3 as the max and with my COL so short compared to everyone else I prob shouldn't go more. Can't wait to get this thing dialed in and see what it'll do. Gotta say with this muzzle brake it kicks like my 22 mag. It's crazy. I bet you don't even need a brake on this caliber but it should let me spot for myself.
