I shot with a guy a couple times, he could make first round hits on gallon sized rocks at 300 yards with a Colt Single Action 45. He always shot one handed also. He did some shooting, I dont know if youd call it exhibition, but he shot cigarettes and other things out of peoples mouths, business cards etc, they held in their hands, he could hit stuff thrown in the air also, though that wasnt something he did at his shoots in the park. All one handed with a 7 1/2" Colt.
Once I asked him if hed been hunting yet that year, he said he shot an antelope. I asked how far, he said about 465 yards. Yes, with the 45. He shot way hot loads for hunting with 225 gr Speer JHP bullets.
