Exactly the kind of input I was searching for, ATCDoktor. In looking further into the internet, there are some good vidoes and various articles/threads in which the opinions mirror what you and Bart have provided.
I have a varmint barrel 22-250 that is deadly (when I git'er done) and I am thinking maybe that is a better candidate for the can. I don't have a bunch of dollars to invest in this project, so the YHM 3200 looks affordable, and from the feedback on the internet they seem to be good units. Not the best, but good.
Whatever decision I make, you and Bart provided great info. Thanks to ya both!
