Load for 7mm Rem. Mag.

Might be loading for a 7 mag and will probably use a 154SST. Would like to use H4831sc. Any other suggestions welcomed, Thanks. Jay

It,s one of the most popular for the 7mmMag in the 154gr bullet or the 139gr. I find it works well for mine,no complaints and love that weight bullet,and Hornady is the only one whom makes those as you probably know. Go for it! van

H-4831 From 53.8 grains to 69.0 grains
CCI-200 Primer

But I preferred:
N-560 From 53.0 grains to 65.7 grains
CCI-200 Primer

Actually fellas, just got back from a bike ride to Gander Mtn. and they didn't have any H4831sc in stock, and VV powders are out of the question around here. So I decided to go with RE22 instead, (3 in stock) and I love the way it goes through my Hornady measure. Besides, the can says "The powder of choice for 7mm Rem Mag and 300 Win Mag". I know it works great in the latter, confident it'll work in the 7 Mag. Anything bad about this powder? Jay

Jay over the years my favorite powder for my 7MM Mag has been IMR 4350 it always seems to shoot it's very best right at or very near MAX/

Nothing at all wrong with RL-22. In fact it's the best powder for many 7mags.

The 69.0 H4831 with a 154 Hornady is a classic 7Mag load from the beginning. This will be near max in most, over max in some. You can shoot about one grain more RL22 than H4831, and will produce a bit more speed in my experience. Shoot whichever shoots best. I like RL22 and a 175 NPartition for my 7 Mag, haven't shot anything else for years.

Probably one of the best powders ever for the 7 Rem Mag. I have had excellent success with this powder.

I have had great results with r-22 and federal 215 primers in the 7mmremmag.However,I prefer 140gr bullets,especially the 140gr tsx.

26" barrel, 68 gr. H4831SC 162 gr. HNDY SST #28452 with moly, 3.34" OAL, measured 3000 fps, .73" 5 shot @50y

Wise choice, R22 is hard to beat in a 7RM. The H4831 has given acceptable accuracy but, not near the velocity of R22 before maxing out. The above 69 grns max listed is well above max in some rifles.

The best accuracy load I've come up w/ for 7RM was 150 NBTs, 65-67 grns R22, Rem Brass, Fed 215 GMMs. Very accurate and produces 3120-3150fps from a 24" tube depending on the speed of the lot and the speed of the barrel at hand.

I've also had good luck w/ the new 140 ABs in two rifles w/ H4831. Good accuracy and descent speed.

I would load a few of the 154s at 64, 65, 66 grains of R22 and see which gives the best accuracy and lowest sd.

Primers can effect your accuracy a good bit w/ the above loads. Wins did ok, CCIs terribly, and Federal Match 215s give the best accuracy in my experience w/ this cart.

Good Luck

My exp. ia the same as reloader's, H4831sc gives exc. accuracy but a bit short on vel. RL22 & IMR7828 give sim. accuracy & 100fps more vel. w/ sim. pressure. I prefer IMR7828, it seems a bit more uniform from lot to lot. H1000 is in the same burning range I just ahven't tried it. H4350, might as well get a .280? You may also try a diff. bullet if accuracy isn't up to snuff. I have had little luck w/ the HIB or SST in my rifles.

I'm still using my original deer load in my 7MM Magnum 139 Gr. Hornady interlock with 68.2 gr. of IMR4350 MV is over 3300fps in a 24" barrel. WW brass and CCI Mag primer. Accuracy is very good. See Hornady Vol. II.

What I want everyone to do now.

Define: Best

This, that and others are always described as best for some particular cartridge.

No one has defined best yet that I've found.

Any old powder that works in the '06 will work just about as well in the 7mmmag, there ain't a nickles worth of differecen except the '06 IS BEST because of the more extensive bullet weights. 7mmags are limited to 175gr max. '06's can and are loaded up to 220grs and many yrs ago they were loaded with 240gr even. I had some.

Ok, guys, what's best??

Best load, the one that gives the best accuracy w/ highest vel. for that bullet weight.

JayJ, you need to rethink your load & check your old data, especially before posting it. Your load is at least 6gr over max. per Hrdy.#III & the IMR site.

Even if your book says it's ok, I doubt that though, you should never use old data for new powders. There are variations from lot to lot, year to year. You still have your fingers & eyes but you've got to be running over 60Kpsi! BTW, have your run those over a chrono?

George, the 06 is almos perfectly balanced, the 7mag is overbore. The best powders for one are not the best for the other IME.

I really like the 7mm RM as it does do exactly what it has been said it will do. It isn't limited to 175's by the way. Berger makes an excellent 180gr and Wildcat Bullets makes them as heavy as 200gr. ( yet to try these)

The Berger 168gr. Match VLD has a BC of .643 listed and the available 180 has a BC of .684! When you start talking about the performance of a .300 WM shooting 180's and 200's it's really not much of a stretch over the 7mm RM is it?

All that said, there are lots of loads that work well. The rifle will have to decide what it likes best. Just match the bullet to the conditions and the game. Nate

Velocity ain't all it's cracked up to be, and for me, the Nosler 160 or original 162 SB, pushed with 79 grains of AA 8700 or similar (as in H870) is hard to beat. Only about 2950, but shoots to one hole, and that is plenty good for what I intend to take with it. If I need more velocity or more bullet, I will go with something bigger...

In a 7mag Encore handgun with a 13" bbl I use 72 gr. of RL22 with 140 Sierra bt's @2800fps and 71gr. of RL22 with the 150gr. Comb. Tech. silvertips @2750fps and get great accuracy from both.

Data for the 7Mag has always been all over the place. My brother always loaded 66 grains of 4350 with a 140 Sierra, bought a new rifle of the same brand and his reloads had brass flow into the extractor slot. The Hornady will take more powder than the Sierra or Nosler bullets. I load 66 grains of RL22 with a 175, chronos 2907, it works in mine. A good many load manuals will show a max of 65 grains with a 160. All this proves is that every rifle is and different and need to be loaded accordingly. The 7 Mag will show more variation than any other caliber I have ever fooled with.

Magnum Hunter1

The perfect load for my 7mm is the 160 Nosler Partition, 80 grains of H-870 in front of a Fed. 215 primer in Remington cases. Sub MOA load at 3100fps. Hard to beat.

24 June 2006, 04:17

fredj338

MH1, you are right on the 160grNP @ 3100fps being "the" load for the 7mag. I think there are cleaner powders out there now that work a bit better than H870.

I've never really figured out why guys buy a 7mag & still shoot 140gr bullets.

24 June 2006, 09:06

Woodrow S

Fred, do you need anything heavier than 140/150gr bullets for 125-150 lb. Whitetails? If I was hunting something Elk size I would use a heavier bullet or a larger caliber gun, as would most hunters. I would think that there are darn few people using the lightweight bullets in the 7mag. for the bigger game. Some people use the 140's for the flat trajectory which comes in handy when taking smaller game at longer ranges. JMHO

24 June 2006, 18:39

fredj338

No woodrow I don't but then you don't need a 7mag for 125# whitetails either. The flat trajectory is not really there. THe diff. between a 140gr @ 3250fps & a 160gr @ 3050fps @ 400yds w/ a 300yd zero is less than 2". The PBR diff. is less than 1". So while I don't need a 160gr bullet, even for pronghorn, they kill very well & I don't have to fiddle w/ a diff. load for this animal or that. If I want to shoot 140gr bullets, I drop to a lighter rifle like my .280. The big 7mags are at their best w/ heavier bullets IMO. I use the 160grNP for an all purpose bullet & drop to a Speer for deer/antelope only. It may even give me a wee bit more barrel life down th road.

I shot 160 Sierra bts in front of H870 for years. Never thought there was a problem till I read soemthing about 870 being dirty. 77-78 grains. Sub MOA. One shot kills on mule deer. This rifle had bad juju for elk. Never got a shot at one. Have killed 7 with my 375. Good juju. 66 grains of 7828 and speer 160 gs gave MOA accuracy.

My favorite bullet for the 7mmremmag is the 140gr tsx.It will penetrate better than a 160gr partition.

Steve, I love the way you narrow down the load! LOL!!

You know stubbl, one of these days I'll have to give the TSX a try. I could never get the 'X' to shoot half as good as the partition in any rifle I have owned except for a #1 in .375h&h. I think that one liked the extra long throat most factory #1s have.

The tsx is an entirely different bullet than the original x.It is much more accurate in most rifes,expands more reliably,and doesn't build up copper like the original x.
