Best powder for 7 Rem Mag

[dennisinaz]

One more for R22. It is not a temp sensitive as everyone would have you believe- at least not at cool-hot temps. Have no idea about COLD weather as Phx doesn't seem to get much of that!!

I hunted with Re22, 180 gr VLD in 2010, but in 2011 I switched to H4350, 150 gr BT.

I do feel that 7mmRemMag is the best cartridge for me.

hi,what charge you using?

IMR enduraon powders especially 7977 showed promise in some work I did.

 

[loinhunter]

+1 on 7977. Cloverleafs at 100 . 71 graIns , cci mag primers and 140 gr. Accubonds. A little less copper wash but a lot more soot!

++1 for 7977. Exceptional with 168 weight class in 7RM.

H1000 is a great powder too.

Don't overlook RL19, especially in lighter weights.

Call me crazy but IMR 4064 w/139 gr is very accurate and turns your 7 mag into something in between 7-08 and 280. Pleasant to shoot if volume shooting ever becomes something you desire to do with your new rifle. MUST use a magnum primer with these.

Best of luck.

My best results are with Rl22 and lighter bullets and N560 with the heavies....

I forgot to mention that I prefer temperature stability as I'm looking for 1 or 2 loads to use year round for hunting. Thanks for the imput.

For hunting a very good choice is the 110ttsx barnes, out to 500yds. If you do a ballistic comparison you will see what i am saying. Speed overcomes bullet weight! Less flight time. More penetration. No lead fragments, less recoil. For powder i like slow ball powder that fills the case like ramshot (Magnum) or( LRT )

Just got a new rifle in 7 Rem Mag and I don't have any experience with the 7 Rem Mag so I'm starting from scratch as far as powder goes. I plan to use 160-170 gr. bullets, probably Hornady SSTs or A-max and am wondering if anyone has any recommendations for a load that works well for them with these or similar bullets? In doing a quick search of Hogdon's site, I noted that Rotumbo produces as high a velocity as anything listed but did it with considerably less powder. I take that to mean, perhaps incorredtly, that cases and barrels may last longer too and that's a good thing. Any thought/tips appreciated. Oh, the rifle is an Weatherby Mk V Accumark with 26" tube.

I have found that most 7rem mags factory barrels like imr 7828 with 160 grain bullets.

I've had phenomenal results with IMR7828 and 168gr Berger VLDs

Don't know about the temp stability thing, as I don't pay much attention to that. I have used Re 25 behind a 160 Partition, at 3000 fps, to kill a number of elk over the years. It is fantastic. Re 33, also works very well with the heavier bullet and I have gotten over 3000 fps, from my 26 inch barrels, using 175-grain bullets.

I've seen a little more velocity with other powders, but best overall accuracy has been with H4831 or the SC version.

I load for 10 different 7 mags all are remingtons. all loads are 68grs h-1000 behind 180gr bergers and we shoot them in 90 degree to below zero with zero problems.

7828 SSC or RL 25 both provide a great combination of velocity and accuracy in my M-70 Classic.

Remington's are also good if you need to jack up a car ! Ha, ha. You need a Tikka.

RL-22, for the longest time, was THEE powder for almost ALL bullet weights in the 7mm Rem. Mag. I used it almost exclusively during "the hunting season" with no problems. If you are really concerned with Temp-Sensitivity, the NEW Viht powders are supposed to be very temp stable and from preliminary reports, they are! I would seriously consider VV N165. Just about right on top of RL-22 in burn rate. VV N560 would be another excellent powder, that is very close in burn rate to H4831sc..

I have had perfectly acceptable results using surplus WC870 in the 7 Mag with the heavier bullets. 175 grains and up will sing with this powder and I don't think you can get enough in the case to get you in trouble, pressure-wise. 175 grain Sierra GK pushed by a case full of this powder is good medicine for just about anything in North America and it shoots very well out of my rifle. I took my 7 Mag out a couple of weeks ago to check zero - it didn't take long. The first two shots out of a clean, cold bore were 1.5" high at 100 and they cut a hole about .45" across. That should work for a long range deer and elk rifle.

I do not want to post my specific load information with respect to powder charge as WC870 is NOT commercial-grade powder (there are mountains of surplus WC870 out there) and there can be significant variation in burn rate from lot to lot. If you decide to give this powder a try, please work up to a proper load in your rifle. Unlikely that you'll encounter pressure on any load that will allow you to seat a bullet with reasonable consistency, but I stand by my caveat.
