In my earliest airgunning days, despite being a novice shooter of only 14, I had a remarkable revelation one day. After spending countless hours with my beloved Crosman 760, it hit me: I could actually shoot better than my gun! I’d reached the point where no amount of practice would improve my groups with the equipment I had. Today, I’m pleased that I’ve graduated to owning a few guns that put me on the better side of those tracks, and the Crosman 2400KT is one of them.
When I wrote the blog on the Winchester MP4, I shot at least three groups with every pellet tested. This turned out to be a lot of work and also resulted in charges (never proven) that I was turning my wife into something she called a “blog widow”! With two guns to test in this report, time limitations didn’t make a repeat performance possible. I tested each pellet at least once from a bench rest using10-shot groups at 10 yards. Pellets that showed promise received further testing, with the best promoted to the 20-yard test.
Did you know that at the beginning of World War II, the United States Air Force had only 800 airplanes? And as the specter of world domination, and finally Pearl Harbor, thrust our nation into an era of unprecedented industrialism and engineering, something odd cropped up in that burgeoning Air Force: Gremlins! These gremlins were intermittent mechanical problems in aircraft that the engineers just couldn’t pin down, and they became legend among the pilots and crews of that era. Why am I telling you this? Because great-great-grand-gremlins have taken up residence in my pellet bin. My two Crosman 2400KTs shoot very well most of the time. But a frustrating number of my groups have a single renegade pellet that insists on thinking outside the box, really opening up its group. Much like their World War II ancestors, there seems to be no rhyme or reason as to when one of my pellet gremlins will show up. Sit back and observe!
.177 accuracy — Wow!
My eyesight’s still pretty good; but as I started measuring my group sizes, I found it helpful to lay the target over a colored sheet of paper that contrasted sharply with both the white target background and the black bulls-eye. This proved especially helpful with those Raggedy Ann domed pellet groups. As unmanly as it may sound, hot pink worked best! I decided to take my accuracy photos the same way to show you what I’m talking about.
There were several different ways I could have arranged my results for accuracy testing the wife’s .177 Sassy Sandy 2400KT with a 10.1-inch Lothar Walther barrel. Ultimately, an alphabetical arrangement of the pellets seemed the most organized — even though you’ll get the happy ending of this story right at the very beginning. With so many different pellets tested, we’ll concentrate on only the best performers.
Air Arms Falcon pellets
The Air Arms Falcon will get us off to a fine start with the .177 2400KT but will also spill the beans on accuracy in this gun. This pellet is one of B.B.’s standbys because it performs well in a variety of guns, and the Falcon does not disappoint here: 10 pellets went into 0.254 inches center-to-center. A pencil eraser’s width at 10 yards — very, very nice!
Ten Air Arms Falcons all squeezed into 0.254 inches center-to-center at 10 yards. We’re just getting started, and the cat’s already out of the bag: The Crosman 2400KT with the .177 Lothar Walther barrel can shoot! Here you also see how a contrasting color background made the groups pop.
Crosman Premier light pellets (boxed)
If B.B. has a standard .177 pellet, the boxed Crosman Premier Light is it. Ten went into 0.302 inches thanks to a single gremlin pellet at the top left of this group, but look closer: 9 went into 0.162 inches center-to-center. Wow! That’s less than a single pellet diameter and as good as we’ll see from this gun! This is one pellet that definitely makes this pistol shoot better than I can.
Gamo Tomahawk pellets
The economy-class Gamo Tomahawk really surprised me! A single gremlin made this group 0.530 inches big, but the other 9 pellets went into an itty-bitty 0.277-inch hole.
H&N Field Target Trophy pellets
The 2400KT liked the H&N Field Target Trophy pellets better than the H&N Barracuda Match, which I won’t show you here). Both pellets came from the same H&N Field Target Sampler pack. My group was 0.329 inches for the 4.50mm head size, and 0.246 inches for the 4.51mm head size — both very nice! The 4.52mm pellets shot widest at 0.368 inches. From my testing of all head sizes for both the FTT and Barracuda Match, I’d say that, overall, the 2400KT seems to prefer the smaller heads — perhaps, due to that choked barrel.
H&N Finale Match Pistol pellets
I shot two groups with the H&N Finale Match Pistol, with the first measuring 0.351 inches overall; and the second measuring larger at 0.426 inches, but with 9 shots landing inside of 0.278 inches. A group that small 90% of the time isn’t bad!
RWS Hobby pellets
Gremlins get into another one of B.B.’s favorites! Ten RWS Hobbys went into a respectable 0.347 inches, but 9 are in one itty-bitty 0.173-inch hole! This one’s a keeper!
The RWS Hobby shoots better than I can! Ten pellets make a decently small group at 0.347 inches; but if you ignore that gremlin to the lower right, and you can see that 9 fit into 0.173 inches center-to-center! That’s less than a single pellet diameter . . . I’m duly impressed!
RWS Superdome pellets
A popular field target pellet, the RWS Superdome, does very well here at 0.300 inches even.
Below is a summary table of all my accuracy results with the .177 Sassy Sandy. While most pellets shot well, space limited today’s discussion to only the cream of the crop.
Accuracy results from 24 different pellets tested in the .177 2400KT with 10.1-inch Lothar Walther match barrel. Eighteen (75%) grouped under half an inch. There were a number of gremlins in these groups, so where applicable I listed the best 9-in-10.
You’ll remember from part 1 that I was using a CV Life 3-9×40 economy scope that had already served me well on a couple other airguns. This was just a temporary measure until I could finance some better glass — specifically something with a parallax-reducing adjustable objective. I was looking for something close to the same weight to keep this gun as light as possible for my wife (the Sassy Sandy’s namesake). The lightest scope whose reviews I liked turned out to be the Hawke Sport HD 3-9×40 AO at 16 oz.
I hoped for a significant improvement in group size. However, for 15 different pellets, the CV Life groups averaged 0.578 inches, while the Hawke groups averaged 0.429 inches — an improvement of only 0.149 inches (26%) at 10 yards. Apparently, parallax was not as much of an issue with the CV Life scope as I’d feared. Note that out of those 15 pellets, however, the Hawke generated the smallest group for 12 of them — so it definitely makes a difference. Another big bonus with the Hawke was having my target in sharp focus instead of blurry, as it was with the CV Life — even at a low 3x.
Remember — smaller numbers are better! The Hawke Sport HD 3-9×40 AO shot smaller groups than the CV Life 3-9×40 for all but 3 of the 15 pellets tested (marked by arrows). Average group size was 0.429 inches for the Hawke and 0.578 inches for the CV Life.
As you can see, the Crosman 2400KT liked nearly every pellet I fed it. The choked Lothar Walther barrel does seem to help keep those groups nice and tight! Performance here was as good as what B.B. found when he tested the very similar Crosman 2300T and 2300S CO2 match pistols at 15 yards. My concluding statement for the 2400KT .177 accuracy test is: “Wow!” In addition to the power of this CO2 pistol in .22, the accuracy of this fine little carbine in .177 is the other most significant thing I have to report about the Crosman 2400KT.
Editor’s note: HiveSeeker’s report goes on to report his findings for his .22-caliber 2400KT, but the report is so long that I’m saving that part for another day. That one will end this series.
