7 Rem Mag powder

[gunluvr]

A friend asked me to help him get set up to reload mostly for his 7RM.
Keeping in mind what may be available, what powders would you recommend to try?

[trigger7mm]

After loading for my 7MM mag for 35 years, I’d say H4831 for lighter bullets, and IMR7828 for heavier bullets.

[marky_mark]

How heavy of a bullet?

[buckman]

I use reloader 25 with 160 grain NP. Can get 3100 fps with max book load.

[shakeyleg02]

Take a look at H1000 also works well in mine

[obsessed1]

At this point if you don't have powder... make a list of all of them and buy whatever you find first..

[Rusty50]

175 gr fusion soft point - 64-68 grains of reloader 25 (all loads very accurate)
68 gr coming in at 2770 fps

175 gr sierra spitzer boat tail - 49.5 -51.5 grains of IMR-4320 (again all loads very accurate) 51.5 gr @ 2600 fps. I am going to work up a load using R-19 for this bullet but haven't got around to it yet.

[stob]

Imr4350 for the 140 to 145 ... imr 7828 for 160 to 175 and fairy dust aka rl26 for 160 to 175 ... with the right gun you are able to get up to 3300 with the 140 ...3200 with the 160 and 3100 with the 175...all around powder is imr7828 which is what the original rounds were built on and originally the off the shelf 175gr round nose was loaded to 3100fps with imr7828...I have tried h1000 and retumbo but it did not work well enuff 4me...work up slowly

[Pioneer2]

With 160gr IMR 4350.............with 140 + 160gr N165

[gunluvr]

My friend will be shooting 160- 170 gr bullets.
Incidentally, he just called me from LA... Said the only bullets available there are monometal...no lead. He's headind to Pheonix in a couple days. Apparently stuff costs less there. I don't know what the selection will be like so I wanted to suggest powders he might be able to find here. Can't wait to hear from him in Phoenix.
He bought a set of Hornady dies in LA for $52 us.

Does he realize that he can't legally bring bullets across the border without an export permit from the USA? I he is caught they will seize the bullets, and he will either be prohibited from entering the USA for a period, or he will be put on a watch list, for future visits.

He says he asked at the border and was told he can bring anything he inquired about including powder. He plans to bring bullets but not ammo.

Which customs,Canada or USA? Canada Customs doesn't care, it is Homeland Security on the USA side that enforces this, as it is USA law.

[brewster29]

Canada border services is ok with bringing in reloading components but US Homeland and Border folks are not ok with individuals exporting those materials from the US without export permits. Good luck to your buddy if he gets checked…

You stop at Canada Customs when you re-enter Canada.

[elkhunter11]

You stop at Canada Customs when you re-enter Canada.

But Homeland security does checks in the USA, catching people before they leave the country. A foreigner can't even possess controlled goods in the USA without the proper permits.

I just texted my friend. We'll see what he says. I know he checked into this.

Make sure that he checks with BATF, or Homeland Security, while in the USA he is subject to their laws.

[270person]

66gr (+-) of RL22 with 150 Barnes TTSX works well in my 7mms. Not screaming but great groups.

He says Canada Customs told him its all ok with them but US Customs occasionally set up a checkstop on the US side. So hes not sure yet, just shopping.

You have been told by people who know. Your friends opinion doesn’t change anything.

[brewster29]

Back to 7mm loads... I got good accuracy and great velocity with 7828 pushing 160's back in the day. Other powders did not yield the velocity that I was seeking. I am sure 7828, RL22 or 26 would still work great but all are hard (impossible?) to find. Check out Vit N165,170 or 560 as these are more readily available.

If I was shooting a 7Rem these days I would be shooting 145 LRX Barnes pushed as fast as possible - like 3300 fps+.

[pintailslammer]

I use H4831sc and H1000
I used H4831sc with my 140 grain Nolser Accubonds
H1000 for my 160 Nosler partition

[Pioneer2]

BTAF and Homeland Security are not even remotely on the same page or same book for that matter.

[fps plus]

You stop at Canada Customs when you re-enter Canada.

The us customs will sometime set up a check before you exit the USA and enter Canada . I have been stopped at a couple and asked about gun “stuff”.

[Pioneer2]

BATF checks parking lots for Canadian plates at gunshows /stores ie Cabelas and forwards them to the Border.Bring a toothbrush ........you might be staying a while.

[Steyr Luxus]

IMR 4831, H4831, IMR7828, H870, H1000, R19, R22 with various bullet weights from 120 gr to 190 gr.

[possum]

Max charges of RL22, RL25 and RL26 works best for me in my 7Rem Mag. But with powder availability the way it is; Whatever he manages to find will be the key.

Man those are Real Missle Loads ! :bad_boys_20: lol RJ

[WinFwt]

Loading IMR 4350 with Barnes 140gr. TSX's in my brothers 7 Rem Mag. Decent speed, very accurate.

Bet his buddy is using taxi cabs

[7magtime]

I've used IMR4831 in my 7mag's with 120's to 160's for years with great results. :)

[Dr. Phil A]

IMR 7828 with 175 deep curls (discontinued) between 2700 and 2800. Elk was 450 yards thru and thru the ribs this year.

H1000 with 162 ELDX hornady

RL 22 and nosler partitions 160 gr

[madatter]

Been using IMR4350 for years....Nosler Partitions,Sierra game kings,TTSX,Hornady SSTs and Interlocks.
140 to 162gr bullets.
Im happy with how it works.
Finding powder....and bullets is the problem.
Pretty much just using Hornady SSt and Interlocks now and Viht N160 is one of powders(along with N165) they recommend.
Viht seems a bit more available so Ill be grabbing some when I see it.
Beggars cant be choosers nowadays.

[elkhunter11]

If you can find them, my go to powders for the 7mmremmag, are R22, and IMR 7828. Powders and bullets are in very short supply, but 7mmremmag brass is pretty much extict in Canada right now.

[colt45]

H 4831 with 150 gr barnes tsx
Been working for me for many years , if I do my part

[Outbound]

I'm using IMR 4350 with 150gr Nosler Partitions.

[goldscud]

IMR 4350 with 145gr Sierra

[DiabeticKripple]

H4831sc but I can’t find any!

I’m wanting to try RL26 and get more speed

[tranq78]

My friend and his son hunt with 7-RM's using Varget and Barnes TSX or TTSX. They hit deer to moose just fine out to 300 yards. I'm sure Hornady GMX will work just as well.

Varget would be way down on the list of good powders for a 7 RM, as it’s far too fast for best velocities with mid weight or heavier bullets. However, if it’s all you have I guess it could be made to work. It’s not a good plan to use fast powders in magnum cases.

I would trade the Varget for something in the 4831/7828/rl26 league.

They might as well shoot a 280rem, or even a 7mm-08 if they are going to limit themselves to 280rem, or 7mm-08 velocities.

On the other hand, after a friend spent days trying to find a suitable powder in stock, to load for his 7mmremmag, I found him an 8lb jug of R-23. We should be able to come up with a good load for the 145LRX or the 140TTSX with the R-23.

Beggars can't be choosers these days. My friend did get a nice buck last year and he had the head mounted.

And how did you score 8# of RL23? That's like a unicorn these days.

Both my sons use 7mm-08. We're using TTSX + Varget for hunting this year. I'm sure other powders may be more accurate but Varget is the least temperature sensitive powder we have.

Varget is a great choice for 7mm-08, but not for 7RM

A simple google search found it, while trying to find R-22. I was skeptical about them actually having it, but a phone call verified it, and my friend gave them a credit card number, and he was in his truck and headed straight there. As far as temperature sensitivity goes, many people put far to much emphasis on it. A difference of 100fps means very little at the distances that most hunters shoot at animals.

Good Point.
Just fir the heck of it , I found a couple of acceptable alternatives to one of the
most popular powders.. . H 4350. Here are a couple that can replace 4350 quite readily..but may be nearly as difficult to find.

All loaded to the same pressure.. 50,000 psi. Compliments of QL

6.5-06 147 ELD-X

CHGE. MV. CASE FILL

IMR Enduron 4451. 47.5 2936 91.4 %

Ramshot Hunter. 57.7 2906. 90.4

H 4350. 50.2 2858 92.3

IMR 4350. 50.2. 2862. 90.8

Note that the Enduron is very temp stable and appears to be somewhat more readily available.
