![]() 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. I take my squirrel hunting way to serious to let a round like this ruin a good day in the timber.A. At best, it’s some fun, fruit busting fodder for a range session. Maybe, just maybe, it works at 25 yards and under, but that’s not how I hunt squirrels. I can’t, in good conscience, recommend this ammo for my squirrel hunting followers. After this big of a disappointment at such a short range, my testing was complete. I at least expected both groups to stack in a clover leaf fashion, but only one out of the two, five shot groups accomplished that. Well that was an unfortunate failure also. ![]() What’s even worse is I attempted two 25 yard groups, expecting the results to be somewhat better. I can’t tell you how much that aggravates me….! I certainly want another round on the market comparable to my coveted Eley Green Box Subsonic, and even Eley screwed that up with the White Box edition. Best Group out of the ten groups I shotĪnd finally all the groups together, just so you know I’m being honest about my results, and not trying to trash CCI Subsonic. I certainly had my hopes up for this ammo, as it’s quite cost effective ($6.50/100), and has a great hollow point cavity. It’s not gonna be a contender for the eastern gray squirrel out of any of my rifles…. I will say that for larger targets like groundhogs, past 50 yards, you could use this round. However I didn’t let the groups stop there. Sadly, from the results of the 10 shot group, this round doesn’t appear to be a contender for squirrel gettin’ duties…. A 10 shot group at 50 yards to start, warms up the barrel and gives me an idea of how this ammo is going to perform. I started with cleaning the barrel with a Hoppe’s #9 soaked patch with one pass, and then putting a dry patch in behind it to start with a unseasoned bore. Here are the results for the first 10 shots: You’ll see in this list of speeds that the 1099 FPS speed barrier was broken, and the auditory report was such that even with a suppressor I was able to make out the supersonic crack down range. I’m a bit of a freak when it comes to squirrel hunting, and I will attempt a shot longer than 50 yards if I have the clearance, and the stability to make such a shot. Knowing this I always want to start with chronograph data so that I have data to plug into iStrelok for holdovers in the woods. These are only what I look for, and may not match how you evaluate your ammunition selection. Must place five shots inside a penny or.My standards for subsonic hollow-point are: I do all my testing at 50 yards for groups that pass my standards. I picked this CCI Subsonic up at to test out to see if it was a worthy contender for squirrel in the fall season. My current favorite is the Green Box Eley Subsonic, which has sadly been replaced with the less accurate White Box Eley Subsonic. Alas, the search for a accurate, subsonic, hollow-point continues on for us squirrel hunters that want to be quiet, accurate, and lethal in the same combo.
