Home Forums Reloading Big Game Rifles 7MM Mag Powder

IMR7828ssc, MRP, and R26 have been my favourites.

These all shoot well in my factory 700 BDL 7mm RM:
7 mm RM. Remington 700 BDL, 140 grain Nosler PT, 72 grains RE 26, 0.38 MOA (favorite load)
7 mm RM. Remington 700 BDL, 150 grain Nosler PT, 70 grain RE 26, 0.66 MOA
7 mm RM. Remington 700 BDL, 139 grain Hornady IL SP, 72 grain RE 25, 0.73 MOA
7 mm RM. Remington 700 BDL, 150 grain CT (combined tech) 68.5 grain RE 26, 0.82 MOA
7 mm RM. Remington 700 BDL, 168 grain ABLR, WLRM, (?,?) 0.97 MOA

Mine really likes Reloader 22.

I would also try some IMR-7828, H-1000, H-4831

Heard good things about VV165 in 7RM’s and 270’s. If I didn’t have a lifetime supply of H4831 I would try it.

I use Reloader 22 and have tried IMR 4831. The Reloader 22 works the best for me.

This^^^^^ plus RL-22 (Same as MRP) unless you're skeered to death of the temp issue

And while I have a good supply of both MRP & '22, I haven't seen either on the shelf since before COVID.

I've used a lot of bullets in the 7 Rem over the years but my rifle favors 3 bullets.
145gb LRX and H 4350 or
160gn Accubond or 175gn Partition using Retumbo for either and 3150fps and 3000+ which is both moving along and very accurate sub MOA loads for my Model 70 with 26" tube.

A very good back up powder for all bullet weights, I found to be IMR 4831.

RL26 and 145 LRX's are my current pick. Ton's of great 7 Rem powders though..











I called it good enough out of the current 7 Rem Mag..

I’ve been using 64 grains of IMR 4350 for the last 50 years, ain’t the fastest but plenty accurate in the 20 or so 7 mags I’ve owned through the years. I have 6 now (working on getting down to one), shoots great in all of them.

That a fine looking rifle beretzs

Yeah, Louisiana ain’t Montana.

I tend to use bullets of 160-168 grains in my 7 mags and powders that have given good accuracy and velocities have been IMR7828 (and SSC), H 4350 and Retumbo.

Dang! Wonder it shoots flat

Appreciate the suggestions. I can get Retumbo for $53 per pound locally, n165 for $300 per keg, IMR4831 for $49 per pound. Also Midway has Staball HD for $275 per keg right now.

I prefer to buy the bigger jugs for the savings but might just get 4-5 pounds of the Retumbo.

Exactly

Temp swings, not so much. Well, mood swings, maybe.

Not sure how it is at your house.

Ha!

I like Reloder 23. I used to use RL-22 but RL-23 is better as it's temperature insensitive and has a decoppering agent.

I have a couple of pounds but would like to find more which doesn't seem to be easy right now.

For sure.

If I missed the story on that rifle, refresh my memory.

That's a fine piece.

It was BobinNH's. About a year ago his boy who doesn't hunt offered it up to me and I grabbed it. It has become my most prized rifle. Love that sucker.

I carried it a bit in Wyoming this year, but when the weather turned sour, I switched to the Mashburn.

It will be a challenge to improve on RL-22. Yet the Reloader series haven't been on shelves for awhile due to a fire in the plant in Sweden a couple of years ago.
