Helping a friend load for 160/162's in his 7 Mag. We continue to see somewhat surprisingly low velocities using Re-22 and IMR7828 (albeit sub-max loads). A look at QuickLoad (and the Hodgdon website) suggest taking a look at IMR4451. Anyone tried it in the 7RM?

Yes. Book max with a 160 grn Accubond is right around a inch at a hundred from a Ruger Hawkeye.

Worked up of course checking the chrono.
It is irrelevant what you think. What matters is the TRUTH.

I've not tried IMR4451, but I've have used R22 and IMR7828. Here's what I'd do, with a 160 grain bullet and R22 or IMR7828 I'd add powder until I got 3000fps+ Then I'd fine tune for accuracy.

I haven't used 4451, but I do use IMR4350 which is 4451's neighbor on the burn chart. I get great accuracy and over 3200 FPS with 140 grainers. Accuracy with 160s is excellent, though I do not have chrono numbers.

66.0grs of Reloader-22 has worked really well with 160gr bullets in every 7mag I've loaded for.Velocities ran between 3000-3100fps depending on the rifle.

You didn’t ask, but heck, I’m using 69.0 grains with a 162 ELDX for close to 3100 FPS and sub-MOA accuracy. https://www.24hourcampfire.com/ubbt...eloader-26-in-a-7mm-rem-mag#Post12181552One shot ruined this guy’s day last year. P
Obey lawful commands. Video interactions. Hold bad cops accountable. Problem solved.

I have had great luck in my Model 70 7mmRM with Accurate MAGPRO.
4451 has good velocity but I haven't been really impressed by any of the Enduron Powders that I have tried TBH.

I like IMR 4350 with 140’s, I have Reloader 22, I need to try it. It’s hard get away from 4350, it works so well.
