I once found out after running numerous patches of abrasive polish down some newly nitrided barrels to clean out residue from the process, the black on my patches was actually steel from the bore. My smith scoped them and said they were the smoothest bores he had ever seen. Too smooth.

You have C4 (Bore Tech I'm guessing)on the way? Just wait for it. Bore Tech products are great.

OK

I just read his latest thread, APS 300 Raptor Preformance Report, and didn't notice any mention of Llilja barrels??

OK... and the 30 Nosler or 300 PRC can't?

A couple of good cartridges for sure, my vote is for the 30 Nosler which will be my next build. All very similar in capacity and design (as well as the 300 PRC), but the 30 Nosler has ADG brass which has excellent reviews. The Blaser has Norma which I have had good experiences with, but I lean...

WOW

Very true, I have seen a good amount of velocity difference using two different brands of brass, everything else the same. There are a lot of variables

I might get some flack for this but oh well, here goes. I don't use loading manuals. If you check out a few different manuals for same cartridge bullet and powder you will get different starting and max loads, fact. I once found the starting load in one online manual to have a higher charge...

Easy fella, just asking a question

What is your source on these capacities?

According to AmmoGuide capacities 300 WM 86.4 30 Nosler 95.9 300 PRC 91.5 300 Norma 101.8 300 RUM 107.2 The 300 WM has a shorter neck than the others so relative useful capacity is maybe 2 grains more

As has been said many times already, every barrel is unique. I learn what my barrels need and clean accordingly. If a barrel looses accuracy around 50 rounds, I will clean at about 40 - 45 rounds. If you wait until you actually notice accuracy dropping off, that is wasted powder, bullets...

To the OP, the choice is clear. If you're considering shooting elk @ 1K the 300 RUM is clearly the best choice. @ 1K you are approaching the edge of terminal performance and the RUM is going to hit with more authority, period. As for the other two, the 30 Nosler edges both of them out, close...
