Great information. Where did you get the barrel treatment?
I have had a lot of luck with H1000, it would be my first powder for this chambering. Short barrel life is relative, with the sheer 3 of rifles I own 1000 rds of life would be plenty. This rifle would be a hunting rifle, not a target gun.
Please keep me in the loop, as far as your barrel and loads are doing.
When comparing the 2 they are very close. It is really difficult to beat a 140 gr @ 3300 FPS, However when shooting a 7mm I am inclined to use the 180. @ 3100 fps it carries well down range and gets there with quite authority.
That said I have one 7 LRM and going on 3 rifles in 6.5 unless I am after Elk I'll use the 6.5s on everything. Not to say the 6.5 is not enough, many elk and moose are killed quite dead with the 6.5 .
I dont think its better at all, the day I took the 6.5 out and stretched its legs, I also had one of our new 7 mags,it's pushing the 168 @3078 fps the two side by side the 6.5 won hands down! The 7 mag took16 moa to get to 825 and when I was shooting 1016 I held 1 moa left wind on the6.5 and 3 moa on the 7! The 7 does have better barrel life but if this meloniting does what I have heard it does, then that wont be the case anymore. I built the 6.5 for my wife but the more I play with it's the more I want one of my own!
Its sporting a break so the recoil is nil! -1000 is by far my favorite powder, I load for alot of calibers, from 243 up to 30/378 wby and I have found h-1000 suitable for all of them, with it I am able to get great velocity with no pressure signs, and more importantly low Es's and great accuracy its the Imr 4350 of its time.
Terry Scott, I got the barrel treatment done at MMI-tru tec, out of arkansa. cost 60 for the barrel and break +20 return shipping. talk to Rodney Lainer. It looks so good we ceracoated everything black but left the barrel alone, it blends into the ceracoat but nicer!
