Hi,
     Just tried a new (to me) powder today and got some surprising results... but first some background. I have been reloading for the .308 Win for some 17 years now, first in a Win 70 Featherweight which I foolishly sold and currently in a Rem 700 Stainless. The biggest thing I have found about  the .308 is that it's hard to come up with a bad load for it. My Winchester grouped virtually every load I tried into 1" or less. The M700 has been just as consistent as the Winchester, but not as accurate- every load I've tried has gone into 1.25" to 1.5" at 100 yds, 3-4" at 200 yds so I figured that was just the accuracy potential of this rifle. Today I tried Reloder 15 with 165 gr Hornady bullets and shot 1 group at 100 yds which measured 1". Then I shot a group at 200 yds that measured .75"! That was all the ammo I brought since this was an experimental load, but it sure shows promise. Incidentally, the reason I tried R15 was to get higher velocities, since it shows the highest in the Speer manual. But my velocities were actually lower than most other powders I have tried. Ah well.
      I guess the lesson is that every rifle is an individual and that we can never learn all there is to know. My personal experience has been that most powders within a reasonable burn rate range perform pretty much the same ( in accuracy terms, not velocity!) and the bullet has much more effect on accuracy, especially in the .308 Win. But this is certainly an exception!
                  Have fun and shoot straight!  ID

ID,

A couple of years ago I bought a 700 with a laminated stock and 26" bull barrel.  I read a lot on snipers and their history.  I read someplace recently that the military has gone to Reloader 15 with its M113? round(7.62 Nato).  Says it gives best performance over a wide range of conditions and temperatures.

In my 308 I use 45 gr. of IMR 4064 with a 150 gr. Nosler Ballistic Tip for a .311 inch group at 100 yds. and 2" group at 300 yds.  The 168 gr. Sierra BTHP Match behind 44 gr. of IMR 4064 gives about the same results with a pt. of impact.  The police and sheriff's snipers around here use Federal 168 gr. HPBT Match ammo which is just about a duplicate load of what I use with the 168 gr.

Just a little note about the Reloader powders. I started using Reloader 22 in my 338. I use 77.5g behind the excellant 225g Nosler Partition. This is a light weight synthetic stocked rifle, and I get consistant groups in the 3/4 MOA range. The more impressive aspect is that I get "just a tad" under 3,000 fps with this loading. Now, I have had a MagNa-Brake installed, which helps me on the bench, but accuracy like that from a dual core bullet is something to tell people about. I wish I could take credit for the load, but I read about it in one of the shooting magazines and tried it.

Gilamonster,
     I used to use R22 in a .338 also, although I used the 210 gr Partition. Didn't have a chronograph then, but it was a very accurate load, grouping 2.5-3 inches at 300 yards.
   I've been quite disappointed in the R15 velocity-wise though. It is the most accurate powder in my .308, but gives lower velocities than any other powder I've tested in 308, 257 Roberts (75 gr bullets) and 30-30 (170 gr bullets) and 30-06 (165 gr bullets). Acually it comes close in the 30-30, but is much slower in the other three, posting velocities 200-300 fps slower than published data and quite a bit slower than other powders in the same rifles.
    The other thing I don't like about it is the smell when it's fired! I know that has little to do with anything, but I usually like the smell of gunpowder!  I probably won't be buying any more of it.   ID
