I've just created two loads which shoot very well (maybe 1/4 moa at 100m), one with AR2206H and one with AR2208 and the AR2208 is 115fps slower.
I was wondering if there is any advantage of the slower speed load?
Would it make much difference to brass life? Is the slower powder less "harsh" on things in general? Will the 115fps make much of a difference? Balistics calcs seem to indicate only an inch difference either way at 500m which doesn't seem too much to me.
Any thoughts to assist me choose one over the other will be greatly appreciated!
Below is the load details with chrono results.

I would go with whichever is more accurate.
Less heat and pressure is easier on the firearm and the brass, but that's a slight enough difference I doubt it would matter. If I don't need the velocity to knock down a silhouette or beat heavy winds for example then I prefer to load lower.
I also prefer AR2206H generally for its versatility but if you're only loading one cartridge it doesn't matter.

Yep, nothing in it. Go AR2206H unless your already using AR2208 for something else.

Are we talking a custom built target rifle and top tier scope or is this just a lucky group of 3 shots .
If a custom I apologise but generally slower burning powders give you lower pressure for the same speed put more 08 in the case see where it goes.
If it is a 308 or 22-250 based case you should be using 2209

If by "208" you mean .204, I use AR2206H in the .204, .223, and .243. I don't own the Creedmoor but I also use it in the 6.5x55mm's and almost everything else I own.

Given these boundaries, TR shooters aim for MAXIMUM velocity; giving them the best chance to buck a fishy wind. ash_hendo, this brings into question your exact question; 06H vs 08 - both get used by national and international level TR competitors. As you have identified, 06H will technically yield a slightly higher velocity, thus should be the obvious choice. Nonetheless, in this context, 08 is still largely preferred over 06H. The reasons being that anecdotally it yields a slightly more uniform burn, being a slightly slower powder. Thus (anecdotally) it's ever so slightly more consistent on paper. It is also (as you mentioned) easier on the brass and action.
Me personally, I used AR2206H in my 30cals for both TR and SR(Service Rifle) for a long time. And I did really good things with 06H. But I still was left searching for accuracy; and after switching to 08 (in my contexts), my scores seemed to go up ever so slightly. Whether this was due to my skills improving vs the powder change, I'll probably never know for sure. What I do know is that AR2208 in my 308s and 303s seems to work really well, and I'm getting excellent case life out of my reloads (I even FLS!). So I'll be keep using AR2208 in my 30cals, and save the AR2206H for the smaller callibers, like my beloved No4-223 service rifle.

damn, typo - 308.... If you use it in the 243 and 6.5x55 then maybe I in the 308, I can then just "standardise" on 2206h. looks like I need to work on that....

10-15 on average in the front lockers. But correct and frequent annealing is critical. Getting back to the 6.5mm, if you really want the optimal powder you should be using AR2209.

I did look at the ADI website first but they only went up to 140gr. I took a very safe load based on the figures there and worked up looking for pressure signs. Although this works for me with my brass and rifle and bullet seating, there is no guarantee it will work in another.
Oldbloke wrote:Don't stress.
AR2208 & AR2206H are both very versatile powders.
IMO 2206H has the edge.
Powder will keep for many years.
Perhaps put the AR2208 into storage and come back to it in a few years if required.
If your not into competition both will do well for heaps of cartridges and AR2206H is recommended for "light" loads. So has that advantage.
It's just splitting hairs.
PS. I'm using AR2208 for both 30.06 and 223.
AR2206H will do the same. Fantastic stuff.

Not for a 147 gn bullet it doesn’t mate.

Anyway, as I said, I just worked up from a bit below the minimum for the 140 in .5 increments watching for pressure signs.
