Nope no pressure signs at 77gr - maybe slightly sticky bolt lift, but nothing noticeable beyond thatAny pressure signs at 77gr? 2,700 seems reasonable from a 24" tube, especially if the barrel is new.
Yep - I was thinking that or trying another pound of H1000 @ 75 gr and seeing if it is right in the same range. If it is, then I will run with that. If not, ditch the old stuff and run with the new lot # lolIf it were me I'd pick an accurate load in that 74.5-75.5 range and run with it, you may gain some velocity after the barrel breaks in. Good luck!
Interesting, so my 2,704 may not be far offI used that combo in the past with a Weatherby Backcountry 26" tube and settled with 77 grains of H1000 and 2730fps was what I was getting. But this barrel is slower than most.
That's significantly higher than what I am getting - from various things I have read online, I should be around 2,850 - 2,900 with 75gr H1000I was getting 2925 in a 24” barrel at 76 grains (compressed)
So with a 2 inch shorter barrel, I would expect it to be around 2,850 - which is similar to @LivetohuntID's numbersThat seems low. I reload for a buddies 26" barrel and he's getting right at 2900 with 215's, 69.5 g H1000, Hornady Brass and Federal 215's.
20-50 fps slower per inch. I could go faster and be marginally hot but decided since I cannot be there for every round that not being hot at all while maintaining 0.5 MOA is the right thing to do.So with a 2 inch shorter barrel, I would expect it to be around 2,850 - which is similar to @LivetohuntID's numbers
Check that...just went back to my notes and it was 2830fps...thought that 2730 # was a little low but still slower than most.I used that combo in the past with a Weatherby Backcountry 26" tube and settled with 77 grains of H1000 and 2730fps was what I was getting.

Wow, I didn't not realize there would be such a differenceI’d put 150rd through that barrel before you really start load development, my 300wsm gained almost 150ft/s once it was really broken in. You may not see the increase I had but you’ll see something.
