6-5-300wby

My brother is asking for help on a DU Weatherby rifle in 6.5-300. He sat it back and was going to sell it but I think he's decided to shoot it. He doesn't reload and saw some ammo was over $100/box occasionally finding some for $60/box

I've loaded for tons of rifles just never messed with this cartridge and thought I'd see if you guys have any first hand advice?

Also if you've been able to find any once fired brass.

Also can you neck down 300 wby without having to turn necks?

Barrel life is about 400 rounds, maybe 600 if you baby it. So make sure you don't really mess around with too many combinations. I like H1000 because it's very temp stable, I like a bonded or a mono bullet. 127lrx, Accubond, or partition for hunting.

Midway has new brass also think Peterson ran some not too long ago so you might be able to find some of theirs. The necking down of 300bee brass might work but it depends on the reamer and brass used.

This is how I obtained my initial brass, no problems and I used a match chamber with .004" neck clearance. Mic'd at .0035" neck clearance on fired brass, .0005" bigger than my 264WM brass, no issues there either. My brass is Remington 300 Weatherby.
My 6.5-300 Weatherby brass is Weatherby, it is dearer than gold here…

Cheers.
