CH312,
I don't have any experience w/ the guns you mentioned but I do have a .17 HMR in a Ruger VMBBZ. It has a matte grey finished stainless barrel and action and a grey laminated stock. I have a 4x12 power scope on it. I had it out last week to sight it in and got some 3 shot groups slightly under 1" @ 100 yds. even though the wind was a little gusty at times. The only thing I didn't like about it was the heavy trigger, so I ordered a Volquartsen sear and spring and now it has a nice, light 2# trigger on it. Can't wait to get back out and shoot it again. If you get a Hummer, you'll love it, I guarantee it!
