It’s worth commenting particularly about the penetration test which I found very intriguing. 22LR shot a consistent 1,071fps with resulting 101.4ft/lb energy from the 39.8-grain bullet. The Lapua bullet has a good pedigree from the target circuit and its subsonic. This had a very thick wax coating and nice hollowpoint design of relatively soft lead when compared with the other bullet types. The slowest velocity ammunition tested was the 40.3-grain RWS bullet with an average velocity of 991fps and an energy figure of 87.9ft/lb. The newer variety was fast for a subsonic at 1,077fps with 102.5ft/lb over the chronograph because it has a lighter bullet. The CCI ammunition has a measured 39.8 grains lead hollowpoint small cavity bullet, very different from the old hollowpoint copper washed bullet. The velocity and energy figures over the chronograph were 1,029fps and 91ft/lb. The Remington is a relative newcomer in the subsonic rankings, weighing in at 38.7 grains, and is almost a clone of the Eley, except it is shorter and it has three lubricant bands rather than two. There is a slight lubricant on the surface and the biggest hollowpoint cavity of all the bullets tested. Next I tested the Winchester subsonic hollowpoints, which weighed a measured 40.3 grains and gave a 1,065fps and 101.5ft/lb. Its actual weight was 40.61 grains and it produced a velocity of 1,032fps and 95.1ft/lb. This is intended to give superior stopping power. The bullet weighs 40.2 grains of hollowpoint design. 22LR subsonic ammunition availableĮley, Winchester, Remington, CCI, RWS and Lapua.įirst was the Eley Subs Xtra Plus, which has a newer, lighter wax lubricant covering. I also looked at each bullet design and weighed them to get a real bullet weight and measured a five-shot string over my chronograph to give a fuller picture of ballistics at the end of the testing. To ensure that each bullet would be equally compared, I matched the way the soap was mounted on the range for each test.įor every bullet, I shot two soap-bar tests and took the mean result. While of course soap does not mimic animal flesh, it is used by certain bullet makers to test their products and it should give a consistent basis from which to compare each bullet’s performance. The test was to measure the depth of penetration and the bullet expansion. The range test for these was 30 yards and the rifle used was a Ruger M77/22 rimfire.Įach brand of ammunition was sighted in at 30 yards and any differing point of impact noted and compensated for on the soaps, which were securely fixed. I purchased some soap bars measuring 2in x 2in and cut to approximately 6in lengths to test the penetration of each bullet. 22LR rimfire subsonic ammunition from varying manufacturers to ascertain accuracy and stopping power at normal vermin ranges. You also need to think how the bullet will perform when it reaches its target – to get the right results you need good performance of penetration or expansion. Getting good resultsĪ responsible shooter is always keen to achieve a humane shot and for this accuracy is paramount. To do that, you need to invest a bit of time and test out what is available in a methodical manner. This may not be best for you however, for getting the best out of your rimfire and achieving your rifle’s potential. Users often make their ammunition choices based on the cheapest manufacturer or on a friend’s recommendation. 22 often doesn’t have the respect and appeal given to stalking rifles and shotguns which results in a disinterested approach towards the calibre. 22 rimfire is largely considered by shooters who have used it to be an accurate vermin cartridge that’s budget friendly and straightforward to shoot with.
