Here's a new wrinkle in the .260 Rem-6.5 CM argument

This article is old but may help some of you decide which is the better choice, the .260 Rem. or the 6.5 Creedmoor.

 
Seems the aurthor discovered the same thing I did about RL17. It can boost velocities in certain cartridges as much as 200 FPS over other more conventional propellants. In the .260 it can show gains from 125-175 FPS which even with bullets seated deeper in the case than the 6.5 Creedmoor, makes it equal to or better than the Creedmoor. I found this out with my .250 Savage and I've read about other people having the same experience with a 6mm Remington. It's a 5 page article but very informative. Check it out.

Son that's somebody with nothing to do with his time but keep me in trouble with mom.

    I plan on messing with RL-17 in my 6.5 Grendel.  Quick Load is shoing it as my highest velocity powder.  Most loads are compressed though.  I am tempted to try it in my 6.5x55 as well.  I think a 6.5x55 loaded to the same pressure as a 6.5 CM would have better velocity, but since it was developed at a much lower pressure and used in guns not intended for todays higher pressures load book velocity is always a lot lower than 6.5 CM.
