Re: 6mm remington reload data
You may have a bit of trouble getting the 115s to 3,000 with the standard 6mm. I am currently shooting a 1-7.5" twist 6mm Ackley slinging 107 SMKs to 3,400 with outstanding accuracy. Tried the 115s but didn't see any advantage over the 107s other than the JBM ballistic printout looked better. The 107s even shot far better than the 115s.
Try some Reloder 22, H1000 or even Retumbo and see how that works out for you on your quest for 3,000 fps.
