Actually I purchased some Aguila Hyper velocity that says;
Aguila Super Maximum Hyper Velocity (1750fps).22lr caliber rimfire ammunition. Features a 30grn solid point lead bullet. It comes packaged 50rds to a box, 500rds (10 boxes) to a brick and 5,000rds (10 bricks) to a case
1750 fps is nothing to sneeze at. I have not been able to try it out yet in the CMMG uppers that I purchased it for but am looking forward to the experience. We do have some 14" steel targets at 325 yards.....hummmmm
Well, if that is true, no need for the 5.7! 30gr. at 1750, that is the 5.7, no?
I had a friend killed by a .22 to the chest. He was a 7' 300lb Samoan, could do the 12mi. road march in a little over an hour. Simply a machine. DOA.
The thing about the .22 is that it is easier to fire accurately, but let's be honest, the .22 is not the best choice for defense. Many defensive shootings happen with the target in a defensive or aggressive position as well. You COULD ask him to keep his arms at his side while you take the shot, but don't count on it. Many times you have to shoot through hands, arms, or take oblique shots.
For assassination, yes, the .22 is probably sufficient. If you don't see it coming, a well aimed shot fired from a hushpuppy is very deadly. But you aren't an assassin.
Firing it at 300m...
Yes, you can do that too. Jerry Miculek shot a balloon at 230+y using a Smith 617, 6", a red dot, and fired upside down with the pinkie double action. He hit it on the third shot. I've shot steel sillhouettes at 300m using a 686+ 6". The thing about them both is that they don't have enough retained energy to do much at that distance. Hitting something and dropping something are two different things.
I used to shoot small targets with my 10/22 at 100yards. Been awhile since I took it past 50 though. I just don't use it for much past that anymore.
For 0-300m, it is hard to beat most M4 platforms. 5.56, 300blk, 6.5, 6.8, you name it. All are good, and most are good past that. The Beowulf is very accurate and very deadly out to 200m (where it falls like a brick after that). .22 is not there. If it were, I'm sure SF would use them for CQB.
If you are hunting deer with a .22, you have problems. I hope you get caught by Fish and Game. I think those shots are BS BTW, maybe TS given the source.
