Darryl,
I don't have any experience cutting off the hanger on a Ruger # 1, but do have some experience shooting Ruger # 1's in matches for the past 5 years and tuning them for accuracy.
Like you I have noticed that on a bench when dry firing with an empty cart. in the chamber some 1-V's do jump a bit, and the lighter # 1's jump even more. sometimes as much as an inch or so at 100 yds, this is not easy to see with a low power scope but very easy to see with a 20 X or more scope, I use a 24 X so the jump is easy for me to see. What I did was install a light weight Speed Hammer, after that all the jump and vibrations seemed to stop, or at least I could not detect any movement, and as long as I could not detect any movement I stopped doing any thing else in that area.
I've been playing around with # 1's for more than a few years and I've never heard of anyone cutting off the hanger to reduce jump and vibration. Maybe I don't hang in the right places.
My thoughts on hammers is that in my experience you should not lighten one below 350 Grs. if you go much below that you may end up with poor ignition, and that's not good for accuracy.
One important thing I learned in all my shooting of # 1's is the # 1 barrel is subject to some weird barrel harmonics, and anything that you may hang on it can/may up-set things in the accuracy dept.
I would like to learn more about the cutting off of the hanger and how much it improves the shooting of the # 1, hopefully someone that has done this will let us know the before and after results.
