Home Forums Reloading Big Game Rifles Pick one only powder for the 7 mag

Another vote for Reloader 22 & 140's

Reloader22 or IMR 4350. I have four 7 mags, I load 140 gr. Ballistic tips with 65 grains of IMR 4350. That load shoots great in all four, all seated the same, full length sized.

Use this in your Kleinguenther?

I'm in the 7828SSC camp under a 160 Partition or Accubond, whichever your rifle prefers.

RL25 a close second.

RL22 works best in my two 7 Rem Mags. I really like IMR7828 as well, but it only works well with my heaviest bullets while the RL22 gives me the best "groups" with all the weights I shoot (140 to 175).

7828 with 160 AB out of model 70 is the tits! So put me down for 7828 as well.

Let’s narrow it down to lighter (120 grain) bullets. What say you?!

I would think something in the 4350/RE-19/4831 range. But those are guesses because I have never wanted to use a 7 mag and a bullet that light.

That is my load, too. 4350 also works good for 160s. Never run any 120s...

RL22 sends off a 110gr Speer HP at “red mist” velocity and shoots well.

Yep.... I’ve seen 3600+ with RE22 and a 120.... they’re not fur friendly.

H1000 gives awesome results in 7 mag

How many of you who responded have experience with more than one powder?




P

This guy.

Looking at loading 120 BARNES ttsx. Looking to minimize recoil, insure complete pass throughs and minimal ballistic bullet drop to 350 yards. I know the BC is lousy, but given the maximum range I plan on for this rifle, I am just looking to maximize point blank range.

Been loading for my 7mags since 1985. What do you think?

Off the top of my head..... I’ve only shot the following powders, with bullet weights ranging from 110 grains to 180 grains, out of about a dozen different 7 Rem Mags:

IMR4350
H4350
RE17
RE19
RE22
RE23
RE25
RE26
IMR4831
IMR7828
H1000
Retumbo
Ramshot Magnum

I’m sure there’s a few others.... they’re just not coming to mind.

Pretty good variety there Dogshooter. I first used one of those Lee hand loaders back in college, and loaded up 160 partitions over 4064 of all things. I guess it was either all I could find or all I could afford. What I do know is that that old Ruger topped with a Vari X 3-9x duplex reticle, would wallop the livin' schittttt outa aoudad and mule deer. I'd sight that thing in 3" high aat 100 and when I guesstimated something about 300 yds, holding that duplex on the top of the target's back, it was history. When I guessed 400 yds, where the bold duplex met the thin duplex wire I could hold spot on and could still wallop the schitttt outa game. I missed alot of longer shots though 'cause I evidently wasn't the best judge of distance.

My numbers and even the powders on my list are about the same...
