On the question of........
center of mass(COM). When I had the Deuce Mag, I had a 3-9 Leupold(LEE-ah-POLD, to go along with lah-POOH-ah ammo
)) that was sighted in about 2.5 inches high at 100yds. I discovered that it then put the bullets 1/3rd the distance UP from the intersection @ 100, 2/3rds the distance up from the intersection @ 200, and 1/3rd the distance BELOW the intersection @300. As a result of trying to hit a hog at 475-500(split-image rangefinder, averaged) I fired at a stone that looked as though(through the scope) it was 1-1.5 inches wide by 3 inches long, sitting pretty much vertical on the side of the mound. When the first shot didn't hit it, I placed the point of the 6 o'clock post on it, and it was soundly hit(I figured if I ever saw that hog there again, I'd have him). Whenever I tried a hog at 100, I aimed for the belly-button, at 200, I'd aim at the grass in front & hit him in the chest or the neck-shoulder-junction, at 300 I'd hold on the top of the head and hit it center of mass. I tried to always hit them there, as that always anchored them; and I only had a couple get away bad-hit as a result of shooting just when they decided to go on feeding. I've had people tell me they, "..only take head-shots at OVER 4 hunnert...". Well, that's all well & good, but based on the shooting I did, & where I did it, there was always the time of flight thing that could be detrimental, & that's why I stuck w/COM shooting. It may be a pest, but it deserves my consideration. That rifle was an L461, & not being bound by the magazine of the L46 or L469, I backed the bullet(Hornady 55 SX & 53 Match) off the lands & the cartridge would feed through the Mauser-type magazine, fine. But I also found it would shoot best as the charge weight was increased in increments until I was about 2gr.(IN THIS RIFLE) over the book limit w/H335. This will NOT work in the detachable magazines unless you develop it, & use the rifle single shot, I KNOW!! But, I never had any cratering w/my loads, whereas I did w/Rem. factory ammo. Hope this helps someone starting w/this great cartridge. Oh yeah, in that vein, with all the GOOD .204 Ruger brass out there, you could probably push the shoulder back, and either neck it up, or blow it out. The good part is, the .204 is cheaper & better quality than the Rem. .222Mag. brass.
