I shot a Vintage 50 target Lewis shoot today. I used a 1897 Black Diamond Trap gun, It was a lot of fun, and old school full choke from 16 yards. It was a 3 man squad and I could see the heat coming off the gun in the second round. My fingers got a little hot with that small forend. I shot a 45, missed a straight away from station 3. I was pleased with that, but it could have been better. I can see what the vent rib is so important. It makes you appreciate what the guys had to deal with on the "old days".
