If you are in the market for a quality subsonic round, that at the moment, I would say is a close second to Eley SS HP, in both cost and accuracy, look no further than SK Subsonic.As I alluded to last week, the ammo situation out there is pretty sparse, and unprecedented. When I do I’ll be sure to report back here. I have to take the time this fall to test the cold weather theory for myself. I’d have to say after using this round exclusively all last squirrel season that it is an excellent choice in the realm of subsonic choices. 1053 (put this round in the group in frustration from making a great group not so good) This was my most consistent feet per second group, however I pulled one shot that made the group go from dime sized to nickle size.Ħ. Again without the chronograph, I would have been doubting my technique.ĥ2.1 grain group was another dime sized grouping. Who would have thought there would be a flyer in this group? Certainly not me. Remember the most consistent weight was 51.9 grains. Shot number four I call a flyer, but it was on the hot side of things. The 51.8 grain group didn’t turn out as I expected, but that is what testing is about. The 51.7 grain group was another good one except for one pesky flyer. It’s the kind of group you have hopes of firing every time you settle in behind your rifle. The 51.6 grain group was one of the most accurate groups I fired. In hindsight I probably should have re-shot this group as the adjustments made don’t give a true testament to the accuracy.Ģ. I made adjustments during this group (51.5) to bring the group to the center of the target. 1055 low right shot (bad technique on my part) I would expect a flyer in this group as the weights were lower, but I would have thought it would have been the 51.0 grain shot as opposed to the 51.2. For my first group I decided to start with the lower weights and I lumped them together, as there were only three rounds. Skies were overcast, 94% humidity, and a slight northeast wind of 3 mph. Weather for the time of shooting, for August, was unusually cool at 74° F. You’ll also see from this ammo test, to every future ammo test that a chronograph is a key element in those head scratching flyers! When the rifle is fired the vibrations that travel through the bipod need to dampened into something, whether that be the ground or something cushioned. I’ve learned this recently, and have been using a bipod incorrectly. If you are shooting with a bipod you certainly don’t want it on a hard surface. I’ve been having pretty good results shooting this way. I set up to shoot off of my table with a bipod and squeeze socks in the rear of the rifle.
As you’ll see that doesn’t mean it will be the most consistent, which still baffles me. It took 5 rounds to finally put that squirrel in the bag, and I think it had something to do with ammo temperature.Īs with the last testing, I weighed out a box of the SK Subs and found the most consistent weight to be 51.9 grains. I had a squirrel last season that I was firing at in sub 45° weather, and missed a 40 yard, rested, shot that should have clearly been a hit. This is why some hunters keep there magazine in there pocket while hunting to keep the temperature of the round warm, to keep accuracy consistent. All you squirrel hunters know that these temperatures are ones you will be hunting in. Somewhere under the 45° F your grouping can open up. I have heard, and plan on testing, that SK rounds are susceptible to colder temperatures. With warmer weather the lubricity increases, making the round very slippery, and with colder weather the lube has more of a “tacky” feel to it. SK Subsonic, if you’ve ever handled any SK, has an almost Vaseline type lube over the entire cartridge. So having another CZ 452 recently pillar and glass bedded, I chose it to get dope for the SK Subsonic HP. Now that my suppressed rifle has been bedded it prefers Eley Subsonic. The SK Subsonic Hollow Point brought plenty of squirrels out of the trees last year for me. That leads me to the round I had my CZ 452 American Suppressed rifle doped for last year. After testing the Eley Subsonic HP ammo and finding the results I did, it is only natural for me to continue to test my other preferred squirrel rounds.
