Try RL22 in the 7RM with 160 grain bullets.I’ve never tried H1000 but hear great things. I’m convinced that those who like IMR4064, Varget, and H380 in the 7-08 don’t own chronographs.
My 7-08 gags on H380, Max’s out 2gr below Lyman #48. Varget and IMR 4064 max out 200fps below RL17. 100fps below max of IMR4350 which is volume restrictive. (Only 46.5gr will fit under a 139-140gr bullet. Only 45.0 under a 150, but it’s a splendid powder for the 7-08.
#2 behind the RL17 is H4350. Realistically they’re very similar. RL17 gives the accuracy of IMR4350 but velocity of H4350.
John Barsness says you can use up to 50.0gr of H4350 under a 139gr Hornady btspt . My gun wants 48.0 H4350 or 47.0gr RL17 for 3,000fps (20”bbl!!!). Accuracy about 1.25moa-three shots. But it’s a “killing fool”! A “Lucky” rifle that punches above its weight.
I use the same powders in the .270 for 3,000fps with 130grbullet. Usually 55.0gr of H4350 or IMR4350. However I’m working through a pound of MagPro and getting great results. 3,200fps from my 24” MkX and 3,100 from my 22” REM M700. Accuracy is excellent.
I’m in the early stages working with the 7mm RemMag.
I’ve gotten acceptable accuracy with some WC860 military pulled down from .50BMG. It’s the same as the discontinued Hodgons H870. (Lots of variability between lot#’s). 77.0gr with a PPU 174grSpt gives 2,900fps and 1.5” for 3-shots.
68.0gr of MagPro gives 3,000fps with a Speer FB Hotcore 160gr. Accuracy approaches 3-shot MOA. Probably my elk load next time I get draw for a permit.
Just last Thursday I shot some 139gr Hornadys I loaded over 64.0gr of H4831. It delivered 3,150fps and two sub 1” 3-shot groups. This is the best the rifle has shot to date. I’m satisfied with it! It’s a pre-bankruptcy Remington M700 CDS 26”bbl -synthetic I got on close-out at Walmart for $378.00
Much cheaper than a new barrel in 280AI for a Mauser or Remington action, installed.
But, I knew going in that it would only beat my 7mm08 by 175-250fps...
the 7mag lives up to the hype. But the 7mm8 is an over achiever! The . 270 is still the standard for a light, flat shooting “deer” rifle, but I prefer the near twin 7mm08.
you’re welcome.
