DS - the barrel is, indeed, choked 0.035" and the right is choked 0.025".
Ran handling numbers with the velcro-on Galco leather pad and 1/2" thick wood spacer I use for extra LOP. Pat and spacer weigh 7 oz!! I hadn't thought of them as that heavy. Numbers with pad and spacer: 9# 2 oz, 5 1/2" to SS trigger, 2.96 unmounted, 11.74 mounted, and HWR of 12.26. That pad hangin' on the end of the butt moves the CG back by an inch, slows the unmounted swing by 20% and slows the mounted swing by 12%. As I said, this is a gun that requires some muscle.
