[QUOTE="elkaholic, post: 988363, member: 13833"] I've had 3 300 RUMs and they are hard on shoulders and barrels!:D The brake is a good idea. I would go with the 3 groove Lilja if I were you. The wider lands lasted well for me and accuracy was great. You will increase velocity about 35'/sec. for each inch barrel length. Melonite treating your barrel is a little extra, but I think it is well worth it. They are supposed to last longer (jury is still out on that) and they do clean up nice and easy and are impervious to everything. I would go with at least a #5 contour and it might have to be that large to flute a 30? The light Palma would also be good. Even though a 10 twist will handle most bullets, my next build will probably be a 9 1/2. Bullets are getting longer all the time and the extra twist may even help at extreme ranges. (velocity makes VERY little difference in twist needed. good luck with your build.......Rich [/QUOTE]
