[QUOTE="sj-pratt, post: 775932, member: 6953"] Sully2 The 260AI or a shortened version of the same will come up a little short in case capacity but would be a fine cartridge. Wildcatting today is a little tougher because there are some many cases and the voids have been filled. Making too little of change and getting just a little improvement questions if it is worth the trouble and expense. The change we looked for was case capacity half way between 6.5x47 and 6.5x284 and Rolland’s thought was maybe with a more efficient case design we could outperform or at least match the performance of the 284 and make it truly a short action round. We looked at 40 degree shoulder and leaving it .100 longer and using Wyatt boxes but instead stayed with 35 degrees and the shorter version, and when we first fire form a case the H20 volume was a little more than I thought it would be. Then Quickload said we could get to 3075 fps and I knew we had something that would attract a little interest and so far so good. I won’t have time to but the other 2 rifles together until this fall the work has piled up and I have to keep busy getting the customers guns out but we are happy with the results and we will see if we can put something together so we can build a few of these rifles for other people.
