well...........I have owned about six rifles in this chambering, including a Ruger #1. The most accurate was a Ruger #3, and I owned it TWICE. The only one I have left is a Winchester Model 43 Deluxe, and it is a sweetheart.
Reloading (or loading) this cartridge has always been VERY VERY fiddly for me. And I have fairly small fingers....... The brass is definitely fragile, and loads are temperamental. In general, I would say that I lose at least one brass out of ten to a collapsed shoulder, and at least 60% of my "Dominion" brass split in the case neck on the first reload.
But it is a HOOT to shoot, and if you have time to work up a load it can be deadly accurate. I reckon I will pretty well always have at least one rifle in the locker chambered for this cartridge.
