[QUOTE="Calvin45, post: 3077297, member: 109862"] Awesome stuff man. But even there I see a bit of a verification of my point! The reason I say that is I have gotten the 120 grain Barnes tac-tx (300 blackout bullet originally) to 4050 fps out of my 26 inch barreled 300 Winchester magnum. Superformance powder, Peterson brass, a fed 215, and HBN treated bullets and bore. That's a hair faster than the 130 grain .30-378 load you mention and only 10'grains less bullet. The point is with these lightweights the monster 30s do no really outrun my boring old .300 Winnie in any way worth noting. With 180 grainers the gap is obviously getting much bigger. I also have a load with the the 225 eld m doing 2760…I bet your 30-378 would absolutely CRUSH that velocity with the same bullet weight. [/QUOTE]
