GAP recently finished up my 300NM hunting build. This cartridge is freakishly accurate. This is a 5-shot group at 102y I shot this afternoon during load work up. 88gr of N570 under a 215. The wind was howling today - 25-30mph - so a little bit of horizontal. Time to stretch her legs!
Those are some pretty good ES and SD numbers. How clean is the N570 for you? I saw someone else said it was dirty. How long is your barrel and I assume you are using 230 gr Bergers?
What kind of brass life are people getting? I've heard reports of 4 reloads on non-max loads.
anybody have the bullet length of the Hornady 225? shorter or longer than the 230OTM?
1.656"
That's 2000 yards of fun right there! Make sure and report back after you've shot her.
I just had a 300 NM built. West Texas Ordnance completed the build and load work up yesterday. I have a 28" Krieger 1-10. I will use the 225 ELD Match with it.

Update to my post: After a trip to Colorado the barrel has settled in and this load is averaging 3120fps with an SD of 9.
What are the specs and weight on your 300 NM hunting rifle?

OK, I'm coming back to this thread as Manners mailed out my new stock on Friday! I can post a pic when I mate them this week, (PRE Cerakote) but I am settling back to the 210 Berger for Hunting
and looking for favorite loads and powder choices and speed at which the 210 Likes to sail at in 300NM of course..
26: rock 10.92 tw
guessing @ 3100fps or so?
any pet loads and speeds for the 210 Berger ?
I'm running standard length mags. Had the barrel cut for Berger 230 hybrids and can load them to where the boat tail sits right at the bottom of the neck and have no issues fitting them in the mag.
My gunsmith has been working on the 210 hunting VLD's for me for the upcoming hunting season.
I think his best accuracy load has been 86 grains of Retumbo and im guessing seating depth very close to lands. Our velocity is around 3100.
Nothing has changed about twist rate has it? Barrel inbound was supposed to be 1-9. Received 1-8. Figured Id check on the latest intel before sending it back.
would there be any issues building a 300nm on a Rem 700 LA action?
Allready have a barreled(300wsm) rem 700 LA action(bluprinted) with a PT&G bolt, and it's time to test something new. the 300nm and 7mm practical is what interests me the most at the moment.
would save a few bucks, if i could reuse the action i allready have. planing a custom 6.5cm build this fall too, so saving some cash would be really nice.
