What is bigger than 22mag?
The 17 HMR consistently offers a higher ballistic coefficient than the 22 WMR. This combined with its substantially faster muzzle velocity grants it a flatter trajectory. Despite this, the 22 WMR’s heavier bullet enables it to transfer greater energy at any point throughout the two rounds’ effective ranges.
What is a 5.7 x28mm compared to?
The original 5.7x28mm loads were actually designed to offer similar terminal performance as 9mm NATO ball. This really isn’t something to aspire to. When it comes to terminal performance the 5.7x28mm has velocity on its side, and that is about it. The projectile is small in diameter (.
Which is better A.22 Magnum or a 5.7?
At 50 yards the 5.7 is going to lose something on the order of 140 fps. The .22 Magnum is going to lose about 165 fps. And that is for 50 yards–far more than most pistol shootings take place at. In terms of terminal performance the velocity is probably not going to be the determining factor. Almost for certain it’s going to be bullet design.
Which is hotter 5.7mm or.22 Magnum?
But I have seen other 5.7mm loadings that have even lower muzzle velocity than the SS197SR round, but there are also loadings of 5.7mm that are hotter too. In terms of overall capability, I think Steve is correct to point out the 5.7x28mm outperforms the .22 Magnum.
What’s the velocity of A.22 Magnum round?
Kel-Tec PMR-30 pistol. Photo by Oleg Volk. Kel-Tec have stated [PDF Link] that a 40 grain .22 WMR round should reach a velocity of 1230 fps from the 4.3″ barrel of their PMR-30 pistol. This works out to 134.40 ft/lbs of energy.
How big of a barrel do you need for.22 Magnum?
Because they’re modular, all you’d need to do would be to get a 16 inch .22 Magnum barrel, a 16 inch 5.7x28mm barrel for the rifle length test, and then get a set of 5 inch barrels in both calibers for the pistol test. This way you can eliminate barrel length as a variable in terminal performance.
