I went out today to re-sight in my Epic One .25 with the 700mm unchocked CZ barrel. I have been trying varios slugs as this will be a slug shooter and today I shot the Griffin .25 60g boat tail HP slugs. My zero is at 30 yards and I have 4 1/2" horse stall mats stacked back to back with a piece of 2" mahogany behind them as the final stop. My regulator is set at 125-130 bar for now. My fps average was 768 for 10 shots with an SD of 3.1. I was able to retireve a couple of the slugs after shooting them I was surprised that they went through 3 of the 4 mats! Most of the pellets I shoot make it through 2 but not 3 with varing calibers and pressures. What surprised me is the muschrooming of the 2 that I found. The pictures are below. The grouping was very close to hole in hole with a couyple that went outside but not by more than about .39 inches. I have an opportunity to go coyote and hog hunting at a friends ranch. We went out the other night and saw 3 bob cats, one coyote, 25 deer, 2 skunks, 3 rabbits and one opossum. The bob cats and the coyote did not get within range that we wanted to shoot so we will go out next week and try again. I will certainly be using these slugs on the larger game!
