.30 Nosler loads desired

[.300 Dakota]

I have just acquired a new .30 Nosler rifle and some Nosler brass. I know there is a little published data out there, but I'm looking for some data that real shooters have generated in their own factory rifles. (No modified throats, etc.) I am going to use my 300 Dakota data as a starting point, as the 2 cartridges are very similar, and I'm not worried about over pressuring since the 30 Nos is rated at 65,000 psi. I can honestly probably go a half grain heavier now, but wanted some input of which powders/bullet combos are working best. The kicker is, I think my FACTORY rifle is equipped with a 1:8 twist barrel (WHY??!!). So I SUPPOSE I MIGHT ought to look toward the 240 grain Hybrid bullets... I'm not sure anything under 180 grains that isn't monolithic or molecularly bonded would survive lift-off...

Thanks

A 1-8 twist will handle anything from 200-250gr bullets. I would shooting something in the 208-230gr range. Personally, I don't load for a 30 Nosler, but I would try some IMR 8133, Retumbo, and H1000 with the bullets weights mentioned above.

My favorite powder for my 30 Nosler is H1000. My chamber throat was extended to use Berger hybrid 215 where the boat tail shoulder is even with the base of the neck. I think I remember the reamer being about .180. I know you said standard chambering but to help in your load choice I use 79.5 grains for a 3085 FPS out of a 26' Brux barrel. 10" twist. .05 MOA average

1:10 has handled everything I've ever tried over 200 grains quite well, if they thought they needed a little extra for the new 250gr aluminum tipped bullet by Hornady, you'd have to take me to a range to convince me otherwise that 1:9.5" (1:9 FOR SURE) would do quite nicely in such a big case. No need for a 1:8 unless you're trying to shoot that bullet in a 300 Savage or 308 Marlin Express (do they still make those?). That twist is for an ultra-long range target rig, which the Browning HC LR is NOT with it's thin fluted barrel and lightweight stock. It's a hunting rifle. And hunting rifles ought to be designed to shoot hunting bullets. I would likely have core slippage if I tried to shoot a 150 grain Sierra out of this thing. I'd have to design significantly reduced loads to survive the centripetal force with a 1:8 twist. I think just for fun, I'm going to load up a group of 130 grain Barnes TTSX and run them as hot as they'll go just to see what happens to a monolithic bullet under that kind of force. Will be like the FMJ bullets used in the 5.56 with 1:7 twists back in 'nam. Shoot something in the shoulder and it comes out its foot.. Good grief! I love forward and progressive thinking, but it CAN go too far. I didn't realize the gun had this twist until I'd gotten home with it, but curiosity would have probably gotten the best of me anyway.

As for powder, yeah. I got a supply of IMR 8133, N570, Retumbo, RL 33, AA8700, Ramshot Magnum, and do have some H1000, Magpro, and even RL 50 and US869, but was just wondering how much of all those I could get away with stuffing in a case. Probably as much as I can in the case of the RL 50.

Thanks for the load with H1000. 0.05 MOA you say?? (Loosening my collar and turning my neck while gulping hard) Man, don't you LOVE those Brux barrels??!!! All I can say is that if this thing does 1/10 as well I'll be screaming for joy! I'll grab some Berger 230s and 240s and maybe some Hornady 225s. I have some 212s, but I don't think they'd be long enough.

I hope this thing proves me to be an idiot not knowing anything I'm talking about, but I WILL take some good old fashioned Missouri-style "Show Me!" convincing!

Thanks guys!

About .225 freebore will get the neck shoulder junction at the boatail of a 215 Berger. H1000 worked good in all 3 -30 noslers I loaded for. My data will not do you any good if you have the saami freebore. If you try and run the Nosler brass hard primer pockets will be junk in 3 reloads.

My nosler has 215 freebore, I agree nosler brass has short life on the primer pockets , have used h1000 and retumbo , currently using retumbo on the upper node 1/2moa at 1k is not a problem, 215s in a 10 twist works great. Good luck cody
