[QUOTE="J E Custom, post: 1863832, member: 2736"] After using the 223 WSM and achieving over 4600 ft/sec accurate groups and stopping, I had thought about a 338 rum necked down to .224 because of the case capacity. I have a 30 x 378 but felt it would be inefficient with to much powder. I had looked at other cartridges and decided that the 338 RUM's case capacity would be about max and if I improved it to 40o shoulder, the efficiency should also boost velocity along with more freebore. I also feel that a 28'' to 30'' barrel a more manageable length and is an optimum length for velocity and accuracy. Mono metal bullets would be mandatory and a slow twist rate for such high speed .224 Bullets. I had good luck with the 1 in 15 twist and to add barrel life a 3 groove barrel with wider lands would be my recommendation. More powder and longer barrels are not always the answer to get extreme velocity, and efficient cartridges that can get more from a charge of powder can make up the difference because it can enhance the total performance of a given powder charge. Just my opinion J E CUSTOM [/QUOTE]
