Standard 300 Nancy Should be close to or a little more than a 300 RUM so 1000 ish if ya take care of her
Thanks
I'm planning on running 225's with H1000 in the mid 2900's to 3000 fps.
Barrel life isn't the first concern, but I'd like to practise with it a lot so 1000 to 1500 rounds is what I'm hoping for.

H-1000 should be a pretty friendly powder and if you keep the carbon ring in check and keep shot strings to 3 or less you will get the most out of it. I assume you using a 1.250" barrel shank and an action with a larger tenon thread?

I wont run a the Lapua's or Norma's on a 1.062" barrel thread any more.

I'm using a Mesa Arms Crux ti Lapua action,
I don't know the specs but it is designed for a 338 Lapua.. I'll check on those specs.
What's your preferred method for removing carbon rings in the throat?
