30 Nosler 2023

I have a #3 bartlein barrel on a kelby action for my 30 Nosler. I throated it for the 245s at 3.75 but for break in, I just threw some retumbo and 215s together and got sweet load without really trying. I haven't even played with the 245s since it shoots the 215s so good but now that the weather is cooling, I am going to try them out.
 
I knew I shouldn't have opened this thread, now I want one! What reamer are you guys using? My understanding is that the SAAMI freebore is suboptimal. thanks

I'm using one I had made by JGS with a 0.200" freebore. Perfect for the 215-230 range. A little short for 245's but it works well with them also as you can see from my velocity. If I was strictly shooting 245's I'd go with a freebore of 0.230". 215's at 3,130 or so and 245's at 2,962.

Awesome!! Thanks.
 
Just purchased a REM 700 pre-fit barrel in 30 Nosler. You guys sold me. Got it 130 bucks off at Carbon Six. Got sendaro profile, 24", 5/8" threads for muzzle brake. No custom throat, but .720 counter bore for m16 extractor. I normally run mack brothers bolts. They are sweet.
