First I want to thank every one here the last year or so for answering a lot of questions I have had on long range shooting. I posted question couple days ago on getting a rest and looking into brand and model. One good thing I only live about 1 1/2 hrs from Brownells store / catalog and can see a lot of items in person. Question I use a sightron 10-50x60 scopes on my creedmoor rifles. They Are very clear scopes. Anything over 20x my heartbeat is moving my cross hairs on my scope. I am just shooting off front bag and now. Are the Shooters using rear bags because they keep butt stock off shoulder so heart beat does not move cross hairs ? Marty
