I don't know how we ever shot maximum loads before P/C come along and saved us all. R5R

Sundog - started with a 31-168b for the ar10 and it worked great. When I got into BO I tried the same concept for the 31-142C (PB) worked good too. Changed the nose profile just a tad and eliminated the groove entirely (31-142D) - groove above GC does the job. Reduce the GC shank a couple thous. for Hornady's to fit easy. Been working with the pistol until the weather came south - I'll try posting some 100yd results with the carbine when temps go up and rain stops. Anyway the 142D feeds and chambers fine, is short for the mag (1.90 IIRC) - longer and the step jams. I size to 3085.

Whatever!
Minor success today with NOE 311-152-SP (GC, Clear PC, .309) over 20.0/H116 @ OAL 2.250. Feed and function is good. Lock back is positive with Brownell's 5.56 20-rd mags. Primers look good. Fifty yard accuracy on the last five shots off hand was a 3" triangle.
Edit to add: that is with the MBUS sights.

It ain't rocket science, it's boolit science.
Wow! 123 posts, 10 that are actually from 4 apparent owners of 300 Ham'r, and 6 that are cast boolit related…..sad. Well, now its 124/11/5/7! All the recent talk about the ham'r is correct. It is exceptionally accurate with jacketed bullets. MOA 10 shot groups for me. Most loads shoot within 1 MOA of POI. Cast is still a work in progress though. The 1-15" twist is almost perfect for the cast boolit crowd. I have run the Lyman 115 GC carbine, the Lyman 130g Plain base carbine, and the 155 Lee GC bullets down my barrel already, all PC. So far all loads are 6 MOA or worse at 100, using a 24x optic to remove as much shooter error as possible. I will keep on trying, but I have had much more luck with the 300 BO shooting cast. Anyone else find a sweet spot of sub 3 MOA with cast in the Ham'r yet?

Mark1 - what load. I have BO 1:10 18" carbine and push 142gr PB PCd to 2100 and get MOA. What alloy? IMHO 1:15 may be too slow.
Whatever!
