Sniper rifle has short range penalty. I just checked. Do not care what is in the item specification. On short range I have 45% chance to hit with my 120 points in small guns. On long range I have 95% to hit as expected. As for Bozar Cassidy can use it but it changes absolutely nothing. As said. Ammo expensive and unavalable before NCR. Casidy has strength of 6, meaning he cannot handle it properly without drugs (which he cannot use for most of the game) or without power armor (which he will not get until San Francisco). On top of that he has an impressive Big Guns skill of 0 (checked it with save game editor). Edit: Ahahaha.... Bozar also has short range penalty. Just checked . And as for Cassidy he can equip Bozar but in a fight he does not shoot with it. Stands still with it or runs away.
