First of all, thanks to all that recommended me to get the Be Still breach plug. He set it up for .299 primers and the W209 came out as clean as they did going in with no black residue on the primer at all and the bolt came back as smooth as butter. I had to stop at shot 20 due to weather but it did not lock up on shot #7 like the factory plug did.
Now, I have MMP12, MMP24, MMP reg black, and the Harvester crush rib black. I did all shots with the MMP24 using the 265 Lehigh CF. The MMP24 were a bit tough to get started (using a spinjag loader with the spinjag bullet starter), but once 1" down the barrel they slide down very easy. Is that what you want? I know some recommenced the 3 petal MMP or crushed rib for tight bores, but is this considered a tight bore or just how loading a sabot with bullet works?
I shot at 100 yards off a rest and did 70gr wt, 75gr wt, and 77gr wt. 3 shot groups.
Both the 70 & 75 weights were exactly 1moa, and the 77 was 1.5 moa.
The first 70gr wt. had 2 bullets close to the same hole. I think I will do my next testing with 67/70/73 and see what it likes best.
