I've recently gotten the long range shooting and in an effort to verify my elevation settings I've build a heavy wood portable shooting table and ordered one of Hart's varmint rests. I assume the pointed feet on the front bench rest is to keep it from moving on a soft surface allowing the rifle to recoil freely. Obviously I don't want to mar up my new coats of polyurethane so I'm contemplating mounting rubber feet on the ends of the spikes. Am I off base on this, or am I thinking straight ? Also what is the typical method of securing the front sand bag to the rest? I comes with 2 grommets on each side. Do shooters just put a shoelace through them and tie them on, or is there something special for securing them in place.
