Finished another project I've been tossing up weather to do or not. This one is a 22 hornet k conversion. I imported a reamer from the us. I have 3 hornets and I picked my single shot nef as the first candidate as I could take the barrel off and see what's going on as I reamed the chamber easier than a bolt action. I reamed the chamber using plenty of lube and going slow. Its turned out well and I had it out fireforming brass for it over the weekend. Happy with it so far..
After a bit of playing around with some handloads it looks like this rifle isn't going to benefit from the extra case capacity. It still likes the load that It was running as a standard hornet. It will still have the benefits of less brass stretch due to the shoulder that forms after fire forming it.
