THE MUZZLE CLAMP REST
I've had good luck using a muzzle clamp on a front rest with a flat surface and a conventional rear bag.. Any rifle tested with this setup shoots as accurately as with conventional sandbag rests front and rear.
It seemed reasonable to extend the muzzle clamp to eliminate the need for the front rest completely. I measured a set of rifles and found that when supported on a rear bag and level, the bore was from 7-1/2" to 9-1/2" above the bench. This gave me dimensions to work with in the design of the "muzzle clamp rest".
On a visit north I got my brother the cabinet maker to make the first try out of wood, then got my son to weld together the second try. Because I have absolutely no design or fabrication skills, my method of attack in a project like this is to badger others into making samples and then throwing each try away until a satisfactory model is made. The second try followed the first into the trash can, but Experimental Model #3 was kept, and seems to fit various rifles well. This is fortunate, since I sensed patience wearing thin in the north.
Here are pictures of #3.
I'm working on the design of a device that, coupled with the muzzle clamp rest, will eliminate the need for sandbags and rest completely.
