Having spent a lot of time doing load development from a bench on a Kimber Montana, I'll pass on what I've learned. With the exception of avoiding free recoil techniques, I don't think it requires any special technique, but it does require attention to consistent technique. I have a cheap bag roughly under the mag box and another under the heel. Adjust so the cross hairs are real close. Then just hold as you would if shooting off-hand. Pull firmly, but not hard, into shoulder and keep cross hairs aligned with target and then squeeze. The hold and forces are the same as field shooting, just a little stability from the bags. You end up with good load development, sighting in, and it will shoot to same POI in the field.
