![]() ![]() 94) or even slower.Įdit: Just saw the post by Trailboss-he beat me while I was typing (yeah, I'm slow) but he is showing the same atmosphere model. But as an example, Volquartzen offers match-grade bull barrels in lengths like 16.5' as well. Some manufacturers offer Ruger 10/22 barrels at 21 inches in length. 22LR firearm, an 18' barrel does an excellent job of taking full advantage of everything the round has to offer. (These are weak, small shocks that generally dissipate within a few diameters of lateral distance.) If you want ammo that is more reliably subsonic you should look for stuff marked at 1050 fps (Mach. If one were so inclined to squeeze every bit of velocity out of a. 97) is far enough into the transonic speed range that one inch outside the muzzle a 22LR bullet would have local shock waves form around the nose and base. I would expect that even ammo with a MV of 1080 fps (Mach. A value of 1125 works just fine, for all practical purposes. My personal favorite is CCI Standard Velocity, perfect blend between price, accuracy and reliability (and it is cheaper than federal bulk pack if you buy a case of 5000 rounds). ![]() Moving out to 150, the gulf between the fastest. 0.303 Lapua Standard Plus 0.312 CCI Standard Velocity 0.319 RWS R 50 0.319 Eley Standard 0.328 SK High Velocity 0.339 Eley Club Xtra 0.340 Winchester T22 0.356 Federal Champion 0.362 Eley Subsonic HP 0.371 CCI Mini Mag 0.376 Federal American Eagle 0.377 Norinco Target 0.380 Sellier & Bellot Club 0.384 Eley Club 0.387 Eley Sport 0. The Stinger has about 50 more velocity and it only dropped two inches. At 100 yards, the subsonic loads dropped more than 7 inches. We zeroed our rifle at 50 yards, so that’s our starting point. The speed of sound will change slightly due to changes in temperature, humidity, altitude, and other factors. Also match ammo or so-called standard velocity ammo is subsonic by nature. So, for these six loads, we fired five-round groups from a benchrest at 50, 100, 150, and 200 yards. This atmosphere model is used by the aerospace industry, academic institutions, and many others. Standard Atmosphere, the speed of sound is 1,116 fps on a "standard" day conditions, at sea level. Most people shooting varmints around their property are killing them at less than 50 feet.Click to expand.Using the U.S. CMMG 22lr Conversion for AR-15 VS Smith & Wesson M&P 22lr Bog Deathgrip. It is ok if it doesn’t reload automatically ~ keeping the breech closed maintains a quieter shot. a 22 caliber AR or an AR with a conversion kit for training the S&W. Sub-Sonic Quiet-22 Segmented HP 22 LR in a 32, 27, 25 Grain or lighter weight fps? Looking at the specs, SV is 1070fps and round nose while Subsonic is 1050fps and hollow point. The CCI Stinger Ammos velocity is 1,640 fps, while the Remington Golden Bullets. 22 LR Muzzle Velocity: This refers to the bullets speed as it exits the barrel. 084, whereas the Remington Golden Bullet is at. Segmenting bullets are much better than solid bullets & preferred over hollow point bullets for a quick humane kill of predators. 1 In my search for CCI SV, I found a source of CCI Subsonic. 22 LR Ballistics Coefficient (BC): The ballistic coefficient indicates a bullets drag factor. Velocity was measured at 10 yards with a Competition Electronics chronograph. Testing was conducted with a Ruger 10/22 semiautomatic rifle and a Simmons 3-9x32mm scope. To dispatch a predator at point blank range in a trap, the speed of the fragmented segments should not be an overkill with damage to the trap and surrounding area if the segments exit the skull or ricochets 22 LR Square-Off We tested each load at 30 yards from a bench, firing five, five-shot groups per load and measuring groups with a digital caliper. Slower segmented fragments do not damage the trap and effectively kill the predator, even if the shot is slightly off-center to the head. I use segmented hollow point bullets to dispatch trapped predators usually (raccoons, opossums, skunks, coyotes etc.) that will attempt to climb my 7’ high chain link coop fence to kill my chickens.
