Jerry was having the time of his life when he got to shoot the .50 at the range.
Steve was pissed when he missed the buck of his life when he missed with his .50 caliber black powder.
I'll know that I have made it when I can blow $1,500 on a DE .50AE show gun.
The bear was pissed and chased me until I opened up his chest cavity with 6 shots from my .500.
