Hands down my .243. My dad bought it used when I was 7 years old. I shot it and the scope hit me in my head and made me bleed. I was afraid to shoot it for a whole year. The next year we were driving down a sendero in Laredo when we saw a doe and a yearling about 500 yards down the road. We walked into the brush and kept looking out in the road to see if they were still there. Eventually, we walked out of the brush at about 25-30 yards. Unbelievably, the deer stayed there. My dad told me to rest the gun on his shoulder. One shot right in the neck that old doe dropped in her tracks. I've shot every deer with that gun except one I believe. Greatest gun I've owned. One year my dad dropped it when we were getting out of the blind messed up the scope really bad. The scope stuck on 3x power. I shot an 8-point with that gun and scope on 3x power at 220 yards. Dropped right where I hit him. Probably, the best shot I've ever made. Like I said my favorite gun.
