![]() ![]() This ammo grouped consistently and decently at 50 yards with the best group at 0.385”/0.736 MOA. I attribute this to age of the ammo and not necessarily the brand. Two of the three did fire on the second go and one would not fire at all even after 5 attempts! This was the only batch of ammo I suffered any malfunction with during testing. Of the 200 rounds fired, there were three duds-rounds which did not fire on the first go. This particular batch of ammo was about 10 years old, pulled from way back in my ammo stash. Again, I believe this was mostly due to the 5–10 MPH wind. I have no group data to report for this ammo at 100 yards other than it was bad. The “groups” were so bad, they all blended together such that I was unable to confidently discern which shots were which. This ammo was the 50 yard winner with the smallest average groups and the best group of 0.320”/0.611 MOA! However at 100 yards, it was a completely different story and one of the worst performers. (Speed of sound is according to the () is 1126 FPS.) Annoyingly, the FPS is not printed on the box and so I had to consult their website. Interestingly, despite the “Standard Velocity” branding, this ammo is actually just slightly supersonic at 1135 FPS. **Armscor Standard Velocity 1135 FPS, 40gr** ![]() Of all the subsonic ammo, this performed the best at 100 yards. At 100 yards, the groups on average opened up quite a bit-best group was 0.649”/1.241 MOA. This ammo didn't group as well as I'd hoped at 50 yards, though it wasn't bad-best group was 0.579”/1.106 MOA. **CCI Segmented HP Subsonic 1050 FPS, 40gr** Only the Winchester wasn't shot at 100 yards. * "Winchester Hyper Velocity" 1435 FPS, 40gr (Supersonic)Īll of the subsonic ammo (ammo with less than 1126 FPS) was shot at both 50 yards and 100 yards. * "Armscor Precision Standard Velocity" 1135 FPS, 40gr (Supersonic) * "CCI Segmented HP Subsonic" 1050 FPS, 40gr There’s a couple quirks in the program and so if you have any tips on using this software, please share! TBH, this is actually a bonus as it allows you to see some other data not included on the grouping labels. One note, OnTarget's image export options leave A LOT to be desired and so I decided to use screenshots of the program, which is why you'll see the OnTarget interface. Going forward this is how I will present my groups. It's a very neat program and makes simple work of calculating group sizes and inputting data. Also, I just purchased a copy of OnTargetTDS (()) which I am still learning. supersonic debate.ĭespite the less than excellent results, I wanted to post everything here so that perhaps you may see something in the data I've missed. And certainly not enough usable data points were collected to draw any meaningful conclusions on the subsonic vs. I managed to squeeze out a few favorable groups when the wind let up, but mostly it was a wash. ![]() My groups at 50 yards were generally acceptable, but 100 yards was a very mixed bag. In another unfortunate twist, wind conditions were a big hindrance the day of the shoot approximately 5–10 MPH. So I had to make do with similar but not exact ammo. My local shop was sold out after having had plenty just a week before. In this case, I was regrettably unable to test the load I had high hopes for: (). (Maybe I'll do an FFL03 some day.) I am limited to what I have on hand and what I can source locally. Match ammo availability near me is zero and because I live in California I cannot have ammo shipped to my home. And with the winds cooperation, very good results at 100 yards with CCI Mini-Mags. If so, it should stand to reason subsonic is also more accurate at 50 yards. I was trying to test the theory that subsonic ammo is more accurate than supersonic ammo at 100 yards. ![]()
