2600-2700 out of 115/110 gr???

As Richard said, 30-30.5gr 10X but only in 11 or 12 twist DMR or SPCII chambered barrels, start a little lower and work up.

Yea it will be an Extreme 16" and ER Shaw SPCII 1:11 twist 16" SS
I've got one of each coming. When I work these loads up I should be ok on CUP pressure? What should it be around? I shouldn't see any brass or primer deformation?

Is 10x a good powder for 68 overall? Can I get the same with H322?

Thanks

You will have a hard time reaching those velocities with H322.

The Xtreme will likely be the faster inch for inch. It will also likely handle the hotter load. Reason I bring this up is so you remember if you work up a good load top load in the Xtreme it maybe to hot for the other barrel. H322 is a bit bulky. It is a very accurate powder and a good beginner powder casue its alsmot impossoible to get too much in the case to be a real saftye issue. 10x is just as accuarte but will get you a godd deal more vel from it.

Right now expecially for barrels that have the specs to take advantage of the pressure curve the two powders I find best for most every load is REl 7 and Rel 10x For a plinking powder add in X-term to save money. If I had to go with only one powder for all bullets 10x woould be it currently. No other powder can do what it can with such a wide range of bullet weights and dimensions.
