We were transitioning to the M107s in EOD from the M82s as I was departing and can't say that I ever got to shoot one before my separation. I do know I could hit small bombs with them at a good distance (HB876s) with the M82A1s. I think we sighted them on an airfield using concrete blocks that day for a quick and dirty zero. They are actually too big of a projectile to be shooting at these little things and we couldn't achieve a reliable detonation. I shot one across the desert three times before saying "fuck it someone else shoot them". We needed something smaller and more along the lines of a 7.62AP round, we were shooting .50BMG API but the point of impact was too large compared to a smaller round to achieve a detonation on the mines.
