Look....I have been shooting since I could walk. Literally. My dad bought a 22LR for me when I was 4. It was mine. I could shoot it almost anytime I asked. He loved to shoot. I got pretty damned good with everything he had. He was KIA Vietnam when I was 8. I continued to shoot (mostly practice for hunting) and learned how to reload sort of on my own. A good neighbor and another guy that owned a sporting goods shop who became my good friend helped me along when they could. USMC didn't really teach me shit but I was Supply so... I thought I was a pretty good shot and taught my brothers to shoot. One of them made the Army shooting team for several years before he married and had kids. Mid-late 90's.
However, I really didn't get into this real precision stuff until about 2005. I was shooting my sorta tuned up R700 BDL 300WINMAG at a range near Boise. They would let us shoot for about 20 minutes then call a cease fire and everyone would walk to inspect their targets. I wouldn't walk because I could see my shots. The guy next to me had a rifle in a MacMillan stock and also didn't walk down there. When they let us start shooting again, I looked at his target. I was impressed! I had a real nice 1MOA group going on with about 20 rounds. His was about 0.5MOA and he had obviously changed aiming points a few times. When the cease fire called again, I asked him about his rifle...300WINMAG. He asked if I wanted to shoot it and I said, "YES SIR!!" I shot a very nice group where I had 5 rounds literally in one hole. It was only slightly larger than .308". I realized I needed better equipment and that has cost me thousands of dollars. Rifles, stocks, barrels, triggers, bedding equipment, scopes, reloading gear, practice, repeat. The mathematician/engineer in me was HOOKED. The science is there without any doubt but there is still art/skill at holding a rifle still enough, repeatedly, in order to make shots go where you intend.
I can say honestly that ONCE I shot a nice 10 shot group at 550 with my favorite 300WINMAG that measured right at 0.75" I attribute that to no wind and all the gravity of all the planets were pulling those bullets into that one little spot. I don't brag about that. That was as much luck and good gear as anything because I have never done it even close again. I'm feeling good when I get 5 that I can fit inside of a closed fist at that range and the shooting team brother is impressed then, too.
5 inside of 1/2" at 600? Sure. Maybe. Once. Or else you should quit your day job and live life large shooting free ammo and custom rifles with a fucked up looking shirt with the name of some ammo or rifle company emblazoned across the back, the sleeves, and stupid looking buttons that look like headstamped cases. You should have a callous on your trigger finger.
But I don't even own a monster truck.
with a straight face and I couldn't
