Do you have any actual data to back that up? It's the old myth that continues to be repeated. "The 7 is ballistically superior to the 30". Fact is, it is not. The 300 SAUM will push a 215 Hybrid almost the same velocity that a 7 SAUM will push a 180 Hybrid. External ballistics is almost identical. Neither is "superior". The 300 delivers a larger cal bullet with more mass down range and therefore it IS a superior hunting round.

I'd like the brass. Will you let me know the price please?

Re: Any reason not to build a 300 Rsaum?

He did write, "in just about every category." Not 100%. I never debate those differences between the 2 because at the end of the day it doesn't matter. Each hunter/shooter is going to (hopefully) learn his ammo's trajectory anyway. The animal dies either way with good shot placement.

I agree with you about the continued discussions between the 7mm and 30s though. It's another parallel to the 270 v. the 280. Who gives a crap when you are shooting at a deer at 350 yards if there's such a huge disparity between bullet selection? I know guys downing deer annually with flat base Speer bullets inside of 500 yards from a 270.

That is simply not true. At one time there was a better selection of 7mm higher BC bullets but that has changed. There is nothing inherently superior about the 7 over the 30 ballistically. The fact is a 30 cal will push the same weight bullet (lower BC) faster than the 7 and it will push a bullet of equal sectional density, form factor and BC about the same velocity. There is no external ballistic superiority. The terminal ballistic superiority goes to the 30.

I don't disagree with you but the whole argument is problematic in that the premise relies on what each cartridge WILL do, not necessarily what it will do with precision and satisfactory accuracy.

Case in point: I have a 7 SAUM and a 300 SAUM, all else identical in every way possible, take the bullets you posed, the 215 and 180 respectively. If everything goes right and I want to shoot a target at 1000 yards, you are saying the 300 wins. Probably true, I don't know, never did the test. But what if the best accuracy comes from the slower speed on the 300/215 combo? Losing 200fps or more? But the 7mm/180 combo shows supreme accuracy at the top velocity achievable....seems to me the 7 is going to win now.

All of the repeated debates on this issue seems to fall on best case scenarios day in and day out. Unfortunately, I haven't experienced this to be reality. But I'm not that experienced either.

Sure will, but he's in KY on his place hunting for a few days. I'll try to remember to call him Monday or Tuesday. You want all of it?
