What's your go to powder for 7mm Rem Mag?

[Slug870]

Hey all,

Just wondering what powder folks are using for their 7mm Rem Mag. Having just picked up my first rifle chambered in 7mm Rem Mag, I am prepping to begin reloading for it. I've read RL-22 and H4831/H4831sc are favorites of many, but I'd like to hear from those on here who have experience. I should add, I'll be loading 150gr Nosler Partitions and 140gr Barnes TTSX.

Thanks for any and all feedback.

I have used R-22 in five or six different 7mmremmag rifles, and velocity and accuracy was excellent with the 140gr TTSX.

I use imr 7828 for my BILs 7 mag with Barnes 150 ttsx. Reloader 22 is great too. Use that with 175 partitions

4350 of either variety works for me

H4831sc gives the best accuracy for my 7RM

 

[threecentsolution]

Which one. I load for a few, don't think there are 2 of them that like the same load and quite frequently they don't like the same powder or bullet.

I'm currently using H1000 for Nosler Accubond 150 and 160 grain bullets. It's ok, nothing more. Great velocities, but the accurate nodes are the slower ones.

That being said, I wish I could give H4831SC but could never find a good supply.

61gr of IMR 4350/160 Nosler Accubond/Win or Fed brass and Fed mag primer....................................66gr of N165/140gr Hornady same brass and primers as the load on the left

RL22 behind whatever 160 gr -ish bullet it likes best. Has worked well for 5 or so different rifles, to date. - dan

Imr 4831 & h1000

I will have to say the IMR7828 for me, not only in the 7MMs but also in my 300s as well as my 6.5x55s.

I used H4831 for 140gr accubonds and retumbo for 160gr - 175gr, that worked well for me.

 

[Hitzy]

H4831 with 162-171gr do the trick for me, IMR 4831 ok as well.

cool thread- i could only really get RE25 for my loads with 162 eldx.
tried "2213sc" /h4831sc but couldnt get the velocity with the heavier bullets- 162 SST...
then could only get the RE25 an loaded the ELDX 162gr-

Am out of that now but have 500g of H1000 - i believe its a similiar thing as the RE25 , being aussie il try find more of it-


keen to see what keeps getting mentioned here-

It's long gone.....best in 264 and 7 mag....for large for caliber bullets is H870. Stopped making it like 20+ years ago.

4831 or rl22.

Started out almost 40 years ago with IMR4831,as it was the most readily available to me at that time,using 160gr Speer spitzers.

IMR 7828 was the original powder for the 7 Rem and made its reputation, way back before it was available to we mere mortals. Between Flintstone powders and the first commonly available chronographs Rem’s 7 almost singlehandedly created the idea that handloaders couldn’t match book speeds.

Getting “book” velocities from a 7mm Remington Magnum sure isn’t that hard.

It's been a few years, my go to was H870 for years. I loaded as much as I could fit into the case.

When H870 was discontinued, I sold my 7's.
