An loads//// velocity//// accuracy?
They seem to fit right into the 30-378 and my opinion is they do away with some of the diminishing returns of the oversized 378 case when used with a 30 cal. The accuracy nodes we have seen are better than that of the 30-378 with 210's. The bullet works very well with the standard 1 in 10 twist too. Get some H-1000 and Fed 215's, seat em at oal 3.800" and work up a load. I think you will be pleased.

h1000 berger recommends 90.5 to 95.5...i read somewhere someone used 94.5 with good luck
