6-5-300wby

[JP_Gunner]

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.

I've settled on the ABLR 142gr as my bullet. Tried the 127gr-129gr options but found bullets 140gr upwards carry more authority way out yonder for med/large game. Getting 1/2" groups with 0.0200" jump.

I think 400-600 rounds is a very conservative estimate on barrel life. You should get 800 or more in a hunting rifle!

Now if you shoot 10 round groups quickly you might get lucky to see 500 rounds of barrel life which is still around 20-30 hunting seasons worth.

6.5x300wby likes SLOOOW powders like RL33, 24n41, N570 especially with the heavies. N570 burns hot so you might want to avoid that one if you are really trying to conserve the throat.....which is pretty much a losing game in 6.5x300wby lol

If its a weatherby vanguard....have fun and shoot the heck out of it then take that Howa 1500 clone and rebarrel it into something else later on.

I seriously considered a 6.5x300wby for awhile. I read all I could find on the cartridge. And one thing I found is that even after guys were fully invested in the cartridge with brass and dies and everything else....few chambered a 2nd barrel in 6.5x300wby. I had a few VERY reliable sources tell me that the cartridge was finicky.

I'm not trying to knock the cartridge at all because it's a freaking monster! I'm just saying that it's definitely far from being house broke. YMMV

WBY occasionally has them for $1 each, but they are currently out of stock. You can request an e-mail notification when it is available. https://weatherby.com/store/once-fired-brass-20-count/
