Good afternoon everyone,

Hope everyone had a great Christmas!

I have a Sako A7 chambered in 7mm Rem Mag and I'm looking to work up a load for it using the 175gr Nosler Accubond Long Range bullets.
I currently have 2lbs of Reloder 22 and 2lbs of Reloder 25 on hand. I have CCI Large Magnum Primers and AGD brass.
Does anyone know of a load recipe range (i.e. starting charge and max load) for each respective powder?

Thanks for the help!

Thanks!
I guess my other question is, will the nominal max load for RL25 vary/be different based on which 175gr bullet I use?
For instance, here's Hornady's reloading data from their 9th edition book for the 175gr Interlock bullet, which is obviously different from the Nosler ABLR 175gr I am loading for.

I should also note that this is the COAL I will be running (see 2nd attachment with the overall length using the dummy round), which is longer than the 3.290" for Nosler and Hornady book data. This is basically the max I can make the cartridge and still have it fit inside the detachable magazine.

I run RL25 in various belted mags, it is far superior to RL22 in my experience. Not as temp sensitive as RL22 either.
I run it in my 7STW with success, I have over 16lbs of the stuff, so I don't slow down using it.
As to max charges, I always look at both the powder company data and the bullet data.
Alliant lists 65.8g max with 175g A-Frame or 68.4g max with Sierra 175g or 65.8g max with 175g Partition.
I normally average these out as no two guns are the same and I do work up to the higher level if the rifle allows.
Another great powder is H1000, or if you can find it, Retumbo with heavy bullets.

Cheers.

A long as the cartridge doesn't jam tight into the lands for the most part.

Are the max loads you listed for 7mm Remington Mag or 7STW?

When I look at the load data listed on Alliant's website for 7mm Rem Mag, I only see loads listed for 175 Speer bullets. Don't see anything for Partitions or Sierra.

I think I should start with 63gr of RL25 and see what kind of velocity I'm getting, as well as any pressure signs. Then increase by 0.5gr increments. Would that be advisable?
 
Well there you are. Loading info. 🤣 Need to get some reloading manuals to start with. I would suggest 1 of each manufactor of bullets. Don't throw them out. They'll become referents later on. I update my manual as they come out. Lots of things are changing with faster twist rates. So that info may not apply in older firearms.
