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

Okay, well that answers that.

Ditto as dog and Mr J said. I have also used h4831 and tried rl 33 with heavys as well. All around I still vote H1000.

RL-22

If I were going to start new load development today, RL-26 would get a trial.

I know this thread is about the lighter bullets, but Re 25 and Re 33 will both go over 3000 fps with 160 Partitions in my 26-inch sps and are very accurate. Elk hate them.

I use IMR 4350 with bullets lighter than 145 in my 7 mags. I like 7828 or RL 22 with heavier bullets. If using lighter than 145 I personally would use only premium bullets as lead core want preform as well. Hasbeen

Reloaded 23 is a pretty good one to try for some of the lighter to mid-weight bullets. I use it with 140gr Barnes T-TSX and get itty bitty groups and velocities in the 3,150 - 3,200 fps range with no excessive pressure signs.
Have a nice mature 25” wide mulie buck on the wall from this past October that didn’t like that combo to well. Shot was 300 yds. Zeroed 2” high at 100 yds, I held high on the shoulder and squeezed the trigger.....buck dropped at the shot.

Works for me,

Yes, 3/4 groups with my old eyes

I experimented with Re 23, when it was tough to find Re 22 for a bit during the Oblowme years. To me, it is a great replacement for Re 22.

Headed to the range today with my Kleinguenther loaded with 160 gr. Sierras over RL 22. If no luck, I'll give the IMR 4350 a try since I have plenty on hand.

I'm another fan of H -1000 in my 7 Rem Mags. I admit I don't shoot many 120 or 140 grain bullets out of them though those weights get primarily shot out of my 7-08's. H-1000 has always been very consistent and gives excellent ES and SD numbers.

RL26

'22...............

Well, opinions are like a------s, everybody has one ! I don't think the critter will know the difference what powder number propels the bullet that just killed them !

I've used both RL-22 and H1000 in my 7mm mags for years. I've found that over time that RL-22 is considerably more temp sensitive than H1000. But either will work with bullet 160 grains or above.

I've used Rl 22 and RL 26 with 150 and 160 grain bullets and both work well. RL 26 is less temperature sensitive.

I used the old Barnes X 120 grain with R22 as it developed the highest velocity with accuracy in my rifle. But if starting over I would try R16 & R23 for their stability and clean burning advantages. If I wanted to get exotic I would also try the VV powders: 165, 170 and N565 & N570.

I had good loads with the 120s and H4831 and H4350 but went with the slightly higher velocity of R22. But I would not do this now. I would pick any of the extreme or newer powders and go with that.

I’ve used both RL22 and 7828 in both my 7Mags, and had better results with 22. My load development focused on the 160 NAB and 175 Partition. Your rifle may be different, but those two powders seem to get an awful lot of attention from 7Mag shooters, and for good reason.

Accurate MAGPRO.
