I bought a Hornet last spring with the intention of having it rechambered to K Hornet. I didn't spend a lot of time on load development, but had it shooting dime size 3 shot groups at 100. Sent it to David White (in Pearl, Mississippi) early August to be rechambered and got it back 9 days later, a couple weeks before Katrina hit. I've only been able to get to the range once to fire form cases but I have no reason to believe it won't be a decent shooter in the new chambering.
