22LR shot a consistent 1,071fps with resulting 101.4ft/lb energy from the 39.8-grain bullet. LapuaĪ 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. This was the slowest velocity ammunition tested 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. This 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. It 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.Ī relative newcomer in the subsonic rankings, weighing in at 38.7 grains. This 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. This has a newer, lighter wax lubricant covering. 22LR rimfire subsonic ammunition available from Eley, Winchester, Remington, CCI, RWS and Lapua. 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. For every bullet, I shot two soap-bar tests and took the mean result. The trick is to mount the soap in the same way on the range for each test. Of course soap is not the same as animal flesh but it does give a consistent basis to compare each bullet’s performance. The test was to measure the depth of penetration and the bullet expansion. Subsonic ammo is more accurate than supersonic Testing 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. With these goals in mind I chose six types of. Poor performance of penetration or expansion can mean less than perfect results. Humane accuracyĪccuracy and the performance of the bullet are essential for achieving a humane shot. Every rifle has an ammunition type that suits it best – although people frequently choose the cheapest or some recommended by a friend. I think this is a pity, because in order to achieve the best from your rimfire and for the rifle to achieve its potential, it takes a little time and methodical testing. 22 is often ranked lower than a stalking rifle or shotgun – so sometimes the calibre suffers from being viewed with a casual attitude. 22 rimfire have found it inexpensive and accurate for vermin.
