9.3x66 Sako Data

I've always been interested in this cartridge and recently acquired a 9.3x62, with the intent of punching it out the x66. (I even ordered a x66 reamer, head-space gauges, and picked up dies.) However, after some additional research, I have decided against this planned conversion, at least for the time being. It just doesn't warrant the added head-aches.


I have two 9.3x62's and have no desire to punch them out. If I had a 9.3x66, I'd shoot it, just don't think the difference is worth that much trouble. I do have a .375 H&H and am building a .404J, so if I want more punch than the '62's, it's in the gun safe.

IMHO.
