Review on Ramset Powder Fastening Systems 1524SDP by Matt Larsen

Has a 2 1/2 inch nail but wanted a little longer to hold more securely in concrete. My old .22 pistol goes into the cement, but not quite on a #4 load. Put another smaller charge in the gun, hit the same nail again and you're done. Completely submerge it without buying a new weapon that requires a red charge. Saved some money. I like 3 inches. It just helps a little more.
