Many of our readers have said they’ve had good luck with the Logun Penetrator pellet, so I thought I would give them a try. I’m always open for a good pellet. I had them in .22 caliber in both 16 grain and 20.5 grain weights.
Logun Penetrators are lead-free, which usually raises a red flag with me. Over the years I have tested a great many lead-free pellets and usually found their accuracy wanting. The best were okay, but for real hair-splitting accuracy I have always found that pure lead pellets are tops. In fact, the most accurate .22 caliber pellet I’ve ever used is the 15.9-grain JSB Exact domed diabolo. For consistency from one gun to another, JSBs are the best – hands down!
Both Loguns are a modified diabolo shape. The domed head tapers to a very straight and long waist, then flares back out at the tail. It’s a unique shape that won’t be confused with any other pellet.
The Logun Penetrator has a different shape! It’s a diabolo, but a very distinctive one. This is the .22-caliber 20.5-grain pellet.
AirForce Condor was the test bed
To test a pellet, you need an airgun of proven accuracy. I have several to choose from, but when the test is in .22 caliber I find myself picking up either an AirForce Talon SS or a Condor more often than not. One reason is because there is no repeating mechanism to get in my way. I can load the pellets directly into the barrel, which produces the best accuracy with any pellet. Another reason is the huge number of shots I get from the removable air tank. I can take a spare tank or two to the range and never have to bother with a scuba tank.
Because the Condor has a power adjustment wheel, I don’t have to run it wide open. The two Logun Penetrators are medium and heavy weight, but in a Condor they are still too light to crack the throttle open all the way. I started the test with the 16-grain Penetrator pellet, which I sighted in at 20 yards before moving out to my 50-yard target. Three pellets got me on paper at 20 yards and I shifted to the for target after that. Group after group at 50 yards went into 1.5 to 2 inches for five shots. I tried a number of different techniques, but the groups stayed the same. The best group with the 16-grain pellet was 1.25-inches, and I have to call it luck because I was never able to repeat it. I shot at power settings 4, 8 and 12 and the groups did not change size. I sighted through an AirForce 4 to 16-power scope mounted on B-Square ultra-high adjustable rings.
I then switched to the Logun Penetrator in the 20.5-grain weight. The first group at 50 yards printed about 4 inches low but measured just over one inch! Things were looking up. The second group measure about one inch and then things improved considerably. The third group was 3/4-inch and I knew I was on to something. One remarkable group doesn’t mean much but a string of them is a good indication that you have an accurate pellet. I was shooting on power setting 8 with should shove a pellet this weight out the spout in the mid 900s, or so.
Once you get dialed-in with a PCP and a good pellet, it’s like eating peanuts – you just can’t stop. Group after group was in the 3/4 to one-inch size and then I got lucky. I was rewarded with a five shot group measuring just 0.406-inches! Those don’t happen often, but the way these pellets were performing, this was the sort of day for it. I tried to repeat that group and got a couple in the 0.600 range but no others under a half-inch.
Using a test standard
After I was satisfied that the 20.5-grain Penetrator was thoroughly tested, I shot two more groups – with JSB Exacts. I know how good they are, so I’m establishing that the rifle is shooting well if I get good groups with them. The two groups measured 0.750-inch and 0.615-inch. No doubt about it – the Condor was shooting well that day!
The 20.5-grain .22-caliber Logun Penetrator works very well in a PCP at about 40 foot-pounds. It’s very accurate and repeatable (holds its zero well). The Condor has a 24-inch Lothar Walther barrel, and I would expect this pellet to do as well in other PCPs with premium barrels.
I did not test the penetration ability, which is a main claim of this pellet. However, nothing else matters unless the pellet is accurate, and the Logun Penetrator 20.5-grain certainly is.
The 16-grain Penetrator did well in the test, though it did not perform to the same level as the heavier pellet. You should make no assumptions about its performance, except the obvious fact that it is not the best pellet for the Condor when it’s operating in the 20 to 40 foot-pound range.
