[QUOTE="Broz, post: 649394, member: 7503"] .690" is a short mag box for a 30-378, is this a Mark V or something else? Anyway, 3.800" is what will feed through an Accumark 30-378 mag box. You still have a ton of free bore in the 30-378 so I would just give it a try. The 230's we shot in the factory accumark shot very well even with all the freebore. There are some reports of them shooting very well in the 300 RUM's too which also has freebore. Our accuracy was running 1/2 to 3/4 moa from that factory 30-378 at 500 yards using H-1000. I feel this larger bullet will help with efficiecy ratio of the large 30-378 case which in some loads shows deminishing returns for the volume of powder. Jef [/QUOTE]
