I did, I dont have the data wrote down because it was just a "lets see what happens experiment"

The 135 SMK is pretty long and I dont think you could seat it deep enough to have the same over all length as a normal 6.8 with out getting crimpin it on the ogive, for magazine fed rounds. You could load them as long as your rifle would allow and load them single into the chamber though, like shooting the 80gr out of a 223.

I still have some left, I use to shoot them out of my 270 but got rid of the 270 when my 6.8 came in to the picture. I could send you a few if you want to try them before buying a box.

Definitely should work for a subsonic,. but it is too long to allow for enough powder in the case.

1.17 is about as long as you can seat and still get good velocity.

My rifle cycles fine with 2.27 OAL

My guess is that 15-20 grains of powder would still be 2-3 moa accurate and should still cycle the weapon.

anybody tried any pistol powders?
