7mm Magnum powder choices

todbartell · Dec 30, 2022

I'm glad I bought enough RL26 in 2016 when it came out to last my lifetime of shooting. It's a wicked powder

Here's a load I did for a friend's Tikka 7mm Rem Mag, 160gr Nosler Accubond over 68.8grs RL26. Often shoots half moa

Doesn't bounce off moose

That some good speed from a 160. I haven't achieved that with my 150. I went to the range yesterday to try 65.0 65.5 and 66.0 grains of IMR4831. My velocity has plateaued at 2975 fps. Groups were similar to last time in the .8 to 1 inch range. According to my Lyman manual, 66 grains is the max charge. I gained about 50 fps for every grain increase from 63 grains up to 65, from 65 to 66 I got an extra 28 fps.

when velocity increase starts to taper off per grain of powder, it's a good sign you're at or just over max

I agree.

thatmikeguy · Dec 30, 2022

I'm seeing mixed thoughts online about H1000.
What are your thoughts on H1000? Some say it's great. Some say it's too slow....
My local gun store has H1000, H4831SC,H4350.

todbartell · Dec 30, 2022

H1000 is better suited for heavier for caliber bullets in the 7mm Rem Mag to get higher speeds, but I did develop this load for another friend's 7mm Mag Tikka T3 SS with the 140gr Barnes TTSX and 73 grains H1000 , 3.313" OAL / .085 jump :

I was also thinking the same thing. (H1000 for heavies 160+)
A 140 grain ttsx will be long for the weight so in that regard it may behave more like a heavy bullet and prefer a slower powder. In my logic anyways...

In other words, I want to use what I have

I'd start with the IMR4831.

Already began using it. Thanks. I'm not quite getting the speed I hoped for but it's working well enough.

I'm getting 2920fps out of a 26" barrel Model 70 Classic with 61gr of IMR4350 under a 160gr Accu-Bond 1/2"or better groups and 40" of moose.

That's pretty good.

I get 2880 out of a 26" barrel Browning A Bolt Stainless Stalker with 64.0 grains of H4831SC and 175 grain Nosler Partition.

The long barrel helps. That's some good speed.

I recently had a Sako Finnbear Deluxe rebarreled to the 7mm Rem. Mag. I haven't had the opportunity to get to the range, however, when I do, I'll be starting off with RL-26 and IMR-7828SSC. The bullet is: Sierra Game Changer 150 grain, my first secant bullet that I have ever reloaded.

I think I will keep an eye out for those powders at my local gun store. My LGS also has some Speer 160 grain pills for an excellent price. It's tempting to pick some up.

I've used those in a friend's 7 RM. His preferred bullet. With RL22 it is very easy to get good accuracy right around the 2900 fps mark. - dan

Win model 70 26 inch barrel
150 g eld x

67 g RL26 @ 2986 FPS

Tryed 3 different loads and groups were terrible.

Should I try a different powder ? H1000 ,US 869 or try a different bullet?

From what I've been reading and learning here, H1000 is best for the heaviest 7mm bullets but If I had some I'd definitely try it. What's the twist rate of your rifle? The eldx will be very long for its weight due to its all copper construction.
