Well, I've had my new virginia rifle for over a week now and have put over 100 round through her, I thought I'd give my thoughts on the rice 42" .58cal c weight swamped barrel and the left handed caywood fowler lock I chose to use on this rifle. 1st the rice barrel has the round bottomed rifling and my 1st impression was how much less resistance I felt when loading the rifle with a tight p/b, it was very noticable, there were no tight spots in the barrel and it shoots great. Even with the thin c weight .58 barrel, the rifle will shoot one ragged hole at 50 yards if benched. The barrel also cleans much easier than any of my other barrels, so I'm glad I spent the extra time and money on it. I was worried about my choice of locks because I'd heard no so great things about the trade lock from some highly respected and knowledgable guys. But I'm left handed and my only 2 choices for a l/h fowler lock was the l&r which I've used and not been very impressed with and this caywood lock. Well I'm happy to report that this caywood fowler lock works great, it showers lots of sparks is very smooth and the internals appear to be quite robust, and the fit is great. It is not too sensitive to flint position and has a good sized pan with a raised lip to keep rain out as well as rain gutters, I even like the way it looks. Overall quality is much better than L&R, truth be told I would have gotten a chambers fowler lock if available in l/h, but the gamble worked out for me. The real test is how it holds up over time, so we will see how she fares.
