At 3250 fps, it produces 1,280 foot-pounds of energy at the muzzle. Since energy is the product of mass times velocity squared, a slower bullet has exponentially less energy than a faster one of the same weight. Is Subsonic Ammo Powerful Enough to Take Big Game? So while subsonic ammo does eliminate the downrange crack, and does reduce the bang at the muzzle somewhat due to its lower velocity, it won’t make your centerfire rifle sound like mouse feet on felt. Walney down the road into a fit of agita. It’s the latter bang that causes hearing damage, reveals shooters’ positions, scares game, and works Mrs. Most of the noise inherent with shooting a rifle, however, comes not from the bullet breaking the sound barrier, but from expanding gases rapidly escaping the rifle’s bore. When a moving object, such as a bullet, breaks that threshold, there is an audible shock wave that sounds like the crack of a bullwhip. What is Subsonic Ammo?Īt sea level, the speed of sound is roughly 1127 feet per second. Still, subsonic ammo does fill an important niche for many hunters and shooters. Your rifle will still go bang, and none of this quieter ammo is powerful enough for hunting big game much past slingshot range. Subsonic cartridges do produce less noise than full-velocity rounds, but there’s no free lunch-as usual. If find a take off Ruger hammer forged heavy barrel take offs for fair price (guy on eBay has them new, unfired all the time) they make good entry level tubes.The label on the ammo box says subsonic, so this stuff won’t spook every deer in the county like your earth-shattering aught-six does, right? Well, sort of. Have pair of 22s at every door and three at some. Need one at every door to house and work for subs and one for faster longer reaching shots. Don't care if you have a dozen premium 22 rimfire tack drivers its never enough. Guess after tomorrow's procedure will start combing all my usual haunts for clearance stocks and bargains on premium barrels. Just need barrels and stocks as purchased a pair of Tactical Innovation receivers with picatinny rail machined as part of receiver and the hole in back so makes cleaning bore from back to front easy if drop the bolt. Tune up kits with extractors, firing pins, spring kits, extended lightweight charging handles, action screws and more. You can lighten a bolt, done it before on my mill but don't think its necessary if use correct combination of springs.īeen stuck at home three weeks now and in lots of organizing while rolling around basement in my comfortable office chair found three Ruger factory 10/22 trigger groups and enough Kidd and Volquartzen parts to build at least five or six triggers. Alloy actually expands at low velocity, whisper quiet and deadly accurate in 1:9 twist or even standard. For small pests am mostly using Eley 38 grain subsonic HPs. but if its a specialty build design it around cartridge plan to use. Also have some general purpose builds that tend to shoot anything o.k. Same with my 22 Mag 10/22s, select twist thats best for ammo (weight, plated/lead, etc) plan to use most. Not always necessary but if want maximum accuracy matching twist to velocity in rimfires will make a difference. On opposite end by slower twist barrels with special chamber for hipervelocity builds use to shoot CCI Stingers. I use 1:9 twist barrels with Bentz chambers for subsonic 10/22s. Also think about twist, slower bullets need faster twist to stabilize well. Wolff, Kidd and Volquarzen sell spring kits to tune your bolts resistance to ammo used. Used a lighter bolt on both but not lightweight. Have two 10/22s built to shoot 38 grain subsonic that are 100% reliable.
