I'm looking for a somewhat reasonable shooting rest for the bench for barrel break-ins and scope zeroing that might also work on the edge of a field for varminting. I'm fine working from a bipod but it isn't always the favored solution. What I've seen so far makes it look like there are inexpensive options, expensive options, and not much in between. The Sinclair Heavy Varmint Rest is heavy and pricey, and the Sinclair Benchrest Style Lightweight Rest seems to suffer faint praise as "being okay for rimfire." Any thoughts here or suggestions? Thanks!
