Any of you fellows found a caliber that this powder seems to excel in. I have only tried with 120gr Btips in my 6.5x55 and wasn't worth repeating. FS

Can't say that it excels over others, but in what I have informally tried it in, I hit the posted velocities per recommended loads in three different rifles, which is not a usual thing.

I also have to add that the accuracy in those were right there with similar tailored loads.

I have just had too many other things in the fire right now to dedicate time to much development. I will be putting it up front after the first of the year however and will know a lot more then.

I use it in my 260AI and it works very well in that cartridge. Not sure it is any better than older powders though.

I shot a pound of it through my .257R with 115grn bt's and 117grn interlocks, but never found a cosistantly good grouping load. I would get some great groups, sub .75, and then some 1.2" groups the next string (45.5grn H10V should have been right at 3000fps). I used my standard RL19 load as a side by side comparison (43.5 RL19, 2800fps), and the RL19 was far and away more accurate and consistant, .6-.7" 3 shots every time after months of comparison. I just couldn't argue with the results.

I haven't given up yet though. I do have another lb of H100V and a variety of 100grn pills to try next with my .257R.

If I can get a consistant load, it will bring the standard Roberts well into 25-06 territory velocity wise.
