Cutting edge .375 MTH_L04

With my rifle I have used the MTH L10 which is the 350gn pill not the 320gn pill. It gets the same velocity as the 350gn SMK, with 1.5gn less powder (Retumbo). So you may be able to use that as a guide to work up a load with the MTH L04.

The L10 gets 3130fps with 133gn Retumbo in my rifle and is the max load that I tried with this projectile although pressure was fine. Accuracy was excellent.
 
shooting a cutting edge 320 gr, only 980 meters, I've to found yet a good load, at 100 m the groups is not so good 1,5 MOA, SMK 350 5 shots in one hole, but a 908 meters the vertical stringing of the cutting edge is good..
