Bag-Boosting Trick for Prone Shooting

If you use these bags when shooting from the ground F-Class style or with bipod, you may find the rifle is too low to the ground for comfort. Yes you can suck in your belly and crank down your front rest, but it makes more sense to elevate the rear bag. Jason Baney has a simple solution that costs under $4.00 in materials.

Get a small 12″x12″ section of 1″ thick plywood and trim it to fit the base of your bag, leaving maybe 1/2″ extra on all sides. Then get some rubberized, waffle-pattern GRIP-IT shelf-liner from your local home improvement center, and attach it to the underside of the wood. Alternatively, if you want a more rigid base (with less ‘give’) for hard, flat ground, use high-durometer unlined Neoprene, available from industrial supply shops. Glue a layer of shelf liner or Neoprene on the bottom and top of the plywood. This will give good grip on your shooting mat and provide a stable, non-slip surface for the base of your sandbag. If you need more elevation, just use a thicker piece of wood, or sandwich two pieces together. NOTE: We’ve used the shelf liner with zero problems on a concrete bench, but some folks say the shelf liner is too squishy for serious BR work. If you’re concerned about that, use the hard neoprene instead.

If you need a riser with more mass, Dave Dohrmann sells high-durometer Neoprene riser pads in 1/2″ through 1″ thicknesses, starting at $22.00. Dave offers risers cut to fit both Protektor and Edgewood footprints. Call Dave at 864-884-0155 or email dbugholes[@]aol.com. With textured surfaces top and bottom, Dave’s heavy pads work equally well to elevate your bag on the bench.
