Thanks especially to Paul and others, I found a wealth of reloading data that I did not get anywhwre else. I still have a couple of questions about powder selection. I just got my Stag model 7 (20", 1:11, SPII) and will start to load as soon as I shoot up enough factory stuff and get some brass. I will use this rifle for targets and am more interested in accuracy than velocity.
It looks like H322, Benchmark, 10X and H4198 are good choices. Unfortunately of the 12+ powders I have, H335 is the closest to those in burn rate , followed by RL7 which may be too slow. I know each rifle is a law unto itself, but if I am using 100-115 grain bullets at 100-300 yards, what would be the first two picksfor accuracy if you had to start buying powders? Right now, the rifle shooys SSA 110 gr prohunter and Hornady 110gr Vmax the best. Thanks for any help.

To answer your question directly, when I started buying powders for the 6.8, it was H322 and RL 7. H322 seems to be sort of the standard for this cartridge, though you read alot about 10X.

So the two powders you mention, H335 and RL7 are on different ends of the burn rate range for the 6.8. RL 7 is considerably faster and is most equivalent to H4198. H335 is slower than H322 by a smidgen. I have used both in the 6.8 and like both. As a rule of thumb, the RL 7 is one of the primary powders for lighter bullets such as the 90 gr. Speer. It is on my loading to do list to try it on 100 gr Rem. softpoints that I have for plinking (started with H4198 with good results). I have worked up loads for H335 for the 115 gr Rem fmj. Considering the bullet (not known for it's consistency or accuracy), I got pretty good results.

So in short, if I was using 100 gr. bullets, I would try the RL 7 first. If I was loading 110 or 115 gr. bullets, I would try the H335 first or go buy a pound of H322.

That's just me. Other will chime in to add their thoughts.

Although H322 and RL10X are both great powders for 90 thru 115 gr. bullets and work well in almost all 6.8's, with that 20"+ barrel your Stag 7 should really like the slower powders like H335 for the heavier 110 thru 130 gr. And, with that good, lower pressure spec barrel, you could use the faster powders like H4198 or RL7 to make the lighter (85 and 90 gr.) bullets fly!

I really like the specs of that rifle; it should have both accuracy and high velocity!

Since you have the 20" barrel and are shooting the 100-115 GR bullets, the H335, H322, RE10x, X-Terminator will be the best choices.

Thanks for the info guys. I fat fingered some of the post, including Mr. Santos's name (my apologies) and that I had RL 7 powder (don't know where that came from - I use RL 15 in my 6.5 Swede and .308). I am going to work up some loads with 335 and the 110 Hornady BTHP's I have. If anybody shows up with powder at the next show, I will get some 322 or 10x for the 100 grain Speer bullets I bought. No one I have found within 60 miles of me carries reloading supplie anymore, so I have to buy at shows or order and pay the shipping. Like ammo, I buy what I can find.

10x and H355 for universal powders with X-term as the cheap plinking powder that actually gets decent accuracy to boot.

When you go to light bullet for max you will want to steer towards Rel 7 4198 1680

As you go heavier you stay with 10x H335 H332. Case volume is a reason for different powders with different bullets etc. as well

Will AA 1680 work for the Speer 90 gr TNT Bullets? I have never seen it mentioned it was always AA 2230. I just aquired some AA1680 and was wondering if I would be able to use for 6.8 rounds.

Check the Speer manual. It shows 27 grains as max for the 90.

What would be a good starting load for RL 7 and Speer 90 gr TNT. I have a 16" SS barrel but it is a 1:9 twist with a SAAMI chamber. I know guys are having good luck with 29.5 so I was thinking of starting with 28 grs and working up to it.

27.5 GR. And work your way up.
