1- go to a shoot, where live .50's are being fired. You'll find that a LOT of .50 owners are very friendly, and open to a newbie cranking off a few shots..
2- pick a LONG range target. 2000 meters, or more.
3- Aim, then fire. Quickly remove hearing protection, and listen. You should hear the echoing boom of the muzzle blast, then if the hit is solid, a definite splat as the round hits.
4- Realize why these weapons are sometimes called "The Hand of God".
Doing this with a tripod mounted ANM-2 is HIGHLY reccomended, and the opportunity to fire the M-85 quad mount should be jumped upon.. A near religious experience..
