[QUOTE="Trickymissfit, post: 724581, member: 25383"] the "crown" is the area where the rifeling and bore meet the face of the barrel at the muzzel. I tried all three 4350's at one time or another, and felt that the ever so slightly faster burn of the AA4350 worked slightly better. There are some other tricks you could do but are near impossible to come by the parts. If by some chance you find some very old Winchester or Remington .257 Roberts cases, you will find that they hold about a grain to a grain and a half more powder (probably over 30 years old). These are good for another 75 to 100fps, but about as easy to find as an apollogy from an ex wife! Bullet tension seems to be critical with the 6mm case, and I found that .004" seems to be about right. Seating depth seems to be more effective in this round than most others. I played around with everything from .015" to .002" off the lands, with .005" to .002" giving the best results. Lastly watch what kind of bullets you select. I had some explode in the air with the nine twist barrels. Vmax bullets worked just fine as well as the Sierras. gary [/QUOTE]
