I'm getting ready to make an order to start loading for my 7mm Rem Mag and I am trying to figure out the best powder that would give the best bang for the buck (pun intended).

Most my manuals have Retumbo for accuracy and that's kind of what I was looking at.

What's a good powder that I can use in several rifles but also works great in the 7mm Rem Mag?

Currently the only powder I have that I have used in rifles is H4895. Other powders on hand are: Unique, Titegroup and Autocomp.

Thanks in advance for any advice.
 
The only powder I've ever used in my Rem 7mm mag has been IMR4350. 40yrs ago there was not a lot of options.

I don't get the best bang for the buck. Your not going to be shooting 1000's of these.
 
I shoot only Retumo now. I have used and also like both H and IMR 4350, as well as IMR 4831, but ive switched mostly do to the added velocity. Accuracy has been about the same between all of them in my rifles and with me shooting.
 
I had always thought that either IMR or H 4831 was the best, but since have come to like IMR7828 in the several 7mags I've loaded for.

When I loaded and shot 7mm Remington Magnum I used Hodgdon-4831 which we purchswed in a 100 lb keg for $50. At that time it was a military surplus powder. I believe that Hodgdon now offers a short cut version which meters more uniformly.
 
Looks like I need to try that 62.5 gr. charge of IMR7828 and the accubonds. I tried IMR7828 before, but with different bullets and was not impressed.

My standard loading for the 7mm Mag is 60 to 61.5 gr. of IMR 4831 with 150 Ballistic tips which has shot well in 3 different rifles.

Next up is RL-22 which I am shooting with 160 to 175 gr. bullets (Nosler and Sierra) and gives me good accuracy.

I used and liked IMR-4350 with 130 to 150 gr. bullets and it gave good accuracy also.
 
sit down and figure out what calibers you are loading then pick the best powder you can load all of the calibers you are using.then buy bulk,same lot,same pressure differential.less powder types means less mistakes.then all you have to worry about is grains.
 
True. Right now I just have the 7mm RM and .223, but have planned to get a 30-30, .243 and .270. :)

Maybe a .308 and .338 down the road. I love shooting rifles. Maybe a .50. :D
 
I use RL22 for 7 mag., but it seems a little too slow for cartridges like .270 win or 30-06. The latter two shoot very well with IMR-4350 and RL19 for me. It really depends on what velocity, and accuracy your trying to achieve. Regarding bang for the buck, that is not part of my reloading goal, only the best performng powders get to make into my empty cases.

I started with rl19, then to rl22. Now I use H4831. 64gr with a 162 amax and a chi 200 primer will impress you. I'm getting right at 2900fps and can shoot it all day long.
 
Last fall I started working on my 7mm loads. My goal was to load a 139 grain soft point bullet to around 7mm-08 velocity for deer hunting. I tried IMR7828, R22, and H4831sc powders. H4831sc was the most accurate on target and R22 was the most consistant as far as velocity. These were with WLRM primers. I am planning on trying regular LR primers to see what happens.
 
I don't know about the other powders mentioned, but if you try RL22 don't expect very good results with standard LR prmers. I tried standard LRP's a couple years ago and got blasted with hot particles, and accuracy and velocities were all over the place.

I'm another fan of IMR4350. My 700 BDL loves it. I also load my 264 WinMag with it. I use it at times for the 30-06 and 270. I haven't tried it yet but I have load data for it for my 30-30 and 303 Brit.
 
I use IMR4064, for both my 7mm mag & my 22-250, I may not get the very top velocity out of it but both rifles are very accurate with it. I shoot 150gr ballistic tip from the 7mm & 50gr ballistic tip from the 22-250
