![]() 22LR bullets heavier than 50gr (and there are only a tiny number of other specialty loads heavier than the standard 40gr). And yet they are the only company that makes. 223 rifle, many of which have 1:9 twist threaded barrels.)ĭo some more research and you will also conclude that Aguila does not enjoy the most stellar reputation in rimfire ammunition. (The closest you can come is to buy an aftermarket specialty barrel from a place like Green Mountain, and then pay another $100 to get someone else to thread its muzzle. 22LR barrel with faster rifling that is also threaded to accept a suppressor. In fact, I have looked long and hard to find anyone who makes a. 22LR barrel is made with 1:16” rifling, and that is not adequate to reliably stabilize those longer 60gr lead bullets. Based on all of the preceding observations, you might justifiably exclaim, “Ah ha! There’s a great idea! I’ll put those in my rifle and enjoy all of the benefits of subsonic shooting for pennies a round, but with improved ballistics!”Īnd you would be right, except for one problem: Virtually every. 22LR ammunition with some odd-looking 60gr bullets. 22 marketplace: Silver boxes of Aguila-brand subsonic. Extra mass at the same speed also increases energy, which enhances terminal ballistics.Īt some point you’re bound to notice a peculiar offering in the. With all that extra room in the cartridge, why not add some more mass to the bullet? After all, holding all else equal, mass is your ballistic friend: It increases ballistic coefficient, which increases a bullet’s effective range by helping it retain velocity and resist atmospheric disturbances. ![]() It takes less than one grain of powder to propel the standard 40gr. 22 bullet has probably been surprised at how much empty space is in the case. 22LR cans are so light, cheap, and efficient, there are a lot of suppressor owners opting for subsonic ammunition to keep shooting sessions as quiet as possible.Īnyone who has pulled a subsonic. Anyone who fires a well suppressed gun will note that even if the muzzle blast is fully contained in the baffles of a silencer a supersonic bullet makes a significant amount of noise of its own: As it travels down range the supersonic pressure waves in its wake produce a “sonic crack.” Since. 22LR ammunition is typically designed to leave a rifle barrel under 1000fps.Ĭompetitive rimfire shooters aren’t the only ones who have discovered advantages to subsonic ammunition. 22LR bullet make it remarkably aerodynamic at subsonic speeds. It turns out that the round nose and stubby heel of a typical. The pressure dynamics around the sound barrier can upset a ballistically efficient bullet on its way to the target. Precision shooters know that keeping bullet speeds out of the transonic region preserves accuracy.
