just wondering if any one uses it in a 7mmRM?
Ive tried it today over a crony just to an average speed of 2980 for 59 grains under a 175smk, where as im only getting 3060 for 65grains of RE22 which im being told is getting hard to get.
I know its not an completly optimum powder, but Im just wondering if its worth continuing load development etc ?
plus im not trying to hotrod it that much
Too fast a powder, try 2217 or 2225 with the 175.

What about ADI 2213SCQuote:

This a generalisation of course, your rifle may be different.
I get 3030 average for 180 VLD Berger over 73gns 2217, 24" barrel, I would expect pressures at the very high end using a fast (comparatively) powder with heavy bullets.
Practically, achieving 3k+ with a 175 SMK in a standard 7mm Rem Mag, you are already about as fast as is sensible, if you really need to go faster, you better go talk to Greg Duley and get him to build you one of his 7mm specials like the 7mm Fatso
Ive got a hold of some 2217 to try,
My barrel is 28"
Great length to get the most velocity from a 7mm Mag, Gunworks Canterbury do ADI sample packs of all the ADI powders, might be worth trying 2225 in your barrel.
i use 2209 , 65gr behind 150gr corelokt does 3150 fps out of my 26 inch browning
Reloader 25 my mate uses for 7mm
Hi, I have 2 7mm Rem Mag that I reload for, they are bothe Tikka's but one hunting and other varmint HB. I use 2217 at 69.5gn behind the Amax and SST 162gn and I get 2960f/s average. My accuracy at 100mt is about 1/2 - 3/4". But I am not a "good" shooter yet. A friend did shot few of my rounds thru his sako 75 finnlight and got pretty much one hole. I hope it help's.
Definitely give 2225 a go in a 28" barrel.
I dont know mate?? Are you sure its safe for others to be allowed to use 2225?? Or is it just a powder that you and a few other tightly controlled individuals should be allowed to use?Quote:

Hey,
Reviving an old thread I know, just had some queries on reloading for the 7mm RM (Sauer 101, 24in Barrel) as per this thread.
I am about to start reloading for this rifle, using once-fired Remington brass. The projectiles I am using are Hornady 120gr SP (no longer made). I have AR2209 ready to go.
I am curious if anyone has any loads for lighter bullets using this powder. The ADI data for all 7mm loads seems a lot lower then what most people are using for 2209 or H4350. I will of course be starting at the middle of the ADI start/max, and working up, just wondering what loads people are running.
I will also be loading 139gr SST using 2209, doing the 120gr first to get some practice withe the rifle.
Also curious if anyone has actual chrony data for factory loads in this calibre? Seems like they are listing them rather fast....
Thanks, Russel.
Try this data as a start. sierra-reloading-data
Im still running 2209 with 175smks and having great results, slow yes but accuracy over speed any day.
the sierra data is pretty close for the projectile weights/speed etc in my experiance YMMV
Thanks Striker, I did find that thread with the data the other day when looking for info.
My experience reloading is limited, only ever done it for my 308 - I didn't think using the IMR 4350 data they list would be close enough in burn rate to use as a guide? From what I understand the H4350/AR2209 is actually the same powder, made in AU, but the IMR 4350 is made in Canada or the USA?
To be certain
7mm+Remington+Magnum
its like all reloading start off low and work your way up. can have variations between powder lots etc
I havent noticed a difference in 2209 being all the same lot so far, cant say the same about RE22 and differnt powder lots when i used to use it
Yeah of course - as per normal, planning on starting at 62gr and doing 5 cartridges each grain up to 65gr, start shooting at the bottom and keep an eye on the cases, and hopefully see whats accurate ETC.
Any signs of pressure in your load, shows as a bit above max? I'll never be shooting a projectile that big, just curious.
I have two loads/rifles
one at 58grain for a factory chambered barrel for 2830fps
and the other 59grain in a custom (bank vault) action min sammi spec chamber 28inch barrel doing 2980fps
no pressure in either
Nice, good speed even for a 28in barrel.
Ever measured factory loads in either barrel? (preferably the factory)
