I have tried most every rest on the market. I can tell you that the difference between a $100 rest and a $300 rest is about a half inch, with a very accurate rifle. That is with me shooting. Your experience might differ. You might be able to shoot perfectly laying the rifle over the seat on a rolled-up coat of a running Harley, but I need something that will hold that rifle perfectly still as I caress that trigger. Some of the rests on the market will show an even greater difference. They look good, but have a bit of flex in the system. If you just want to get pretty good groups, to test your handloads and such, most anything will do. When I am trying to see just how accurate a rifle/ammo/scope combo can be, I always use a Target Shooting, Inc rest. I have found nothing better. I bought my first one years ago, and never regretted spending the money. There is something very satisfying about shooting tiny little groups.
