Today’s report is the continuation of a guest blog from reader HiveSeeker about his Crosman 2400KT. I actually took what was his Part 1 and broke it into 2 sections, so this is the second half of the original Part 1.

If you’d like to write a guest post for this blog, please email me.

Over to you, HiveSeeker.

Crosman 2400 KT
The 2400KT CO2 carbine is available exclusively from the Crosman Custom Shop.

This report covers:

• No tipping, please
• Trigger tips
• First shot

Let’s pick up where I left off. I’ve just introduced you to the Sassy Sandy and HiveSeeker carbines — two 2240KT carbines I set up for my wife and me. My wife’s carbine has the CV Life 3-9X40 scope, which is light enough for her.

The scope I mounted was a Leapers 4-16X40. Although a similar scope is available with 11mm dovetail airgun rings, that version was out of stock everywhere at the time of my purchase. I ended up ordering the version with Picatinny rings (otherwise identical as far as I can tell), and buying UTG Accushot high profile airgun rings separately. This is a large scope! It has to straddle the breech opening, and high profile rings give a little more finger room for pellet loading in addition to accommodating the large objective. Having to straddle the breech, there’s also less horizontal wiggle room for positioning the scope for best individual eye relief.

To hedge my bets, I also ordered a set of narrower, 2-screw UTG Accushot scope rings in case my scope needed a little more horizontal leeway. I didn’t end up needing them, but other shooters have. Keep this option in mind if you purchase this gun and choose to scope it. [Editor’s note: The 2-screw Accushot rings are no longer available.]

Narrow 2-screw scope rings allow more horizontal leeway if needed to correctly position the scope for best individual eye relief. Though not as secure as 4-screw rings, they’re quite adequate for the low-recoil CO2-powered 2400KT.

The first time my wife saw this very full-sized scope on my 2400KT, she exclaimed “Your scope is bigger than your gun!” At 22.3 oz., this scope almost does outweigh the pistol and stock! However, this setup was very similar to what my acquaintance had who originally recommended the 2400KT to me, and it worked very well for him. At the time, I didn’t realize that I was entering already-charted waters, but if you want to see a similar setup, check out B.B.’s evaluation of the Crosman Outdoorsman 2250XE.

While my combination looks unwieldy, it shoots like a dream — though I would definitely recommend that you avoid going any heavier on the scope. Women and youth shooters and those seeking a lightweight carbine will want to track down different optics, like the Hawke scope mentioned in part 1.

“Your scope is bigger than your gun!” my wife exclaimed the first time she saw this Leapers UTG 4-16×40 mounted on my 2400KT. It looks cumbersome and you would definitely not want to go heavier, but this combo shoots like a dream.

No tipping, please
I’ve already mentioned that high-profile scope rings provide a little more finger room for pellet loading in the 2400KT. This is very helpful, because pellets absolutely love to tip nose-down or flip backwards in this breech! This is a quirk of the entire 2XXX family of Crosman CO2 pistols, and it occurs with both plastic and steel breeches.

While researching this blog, I came across a multitude of specialized techniques for loading these guns. Ultimately, my wife and I found that a pellet pen is a great help, though not a complete solution. Certain pellets are still quite prone to sit skirt-up, or flip backwards (skirt-first) as you try to load them.

I found that by resting a properly-oriented pellet on the flat surface to the right of the breech channel, and then rolling it gently into the channel with my fingertip, I could usually get it to stay correctly oriented until loaded. For pellets that like to flip backwards as you load them, I found that tipping the muzzle of the gun up would often cause them to flip back into nose-first position ready for loading. This wouldn’t be too difficult while shooting offhand, but repeatedly having to tip the barrel up was a major inconvenience during all the benchrest shooting I did.

Short, “fat” nose-heavy pellets were the worst offenders, especially domed pellets like the .22-caliber Crosman Premiers, with that nice round nose to roll on. Longer-skirted pellets were much better behaved, especially flat-nosed wadcutters. This problem was much worse with the .177 pellets than it was with the .22 pellets. My wife and I both got better at pellet loading with time, but I was still tipping the occasional renegade pellet back into position up until my very last test shot.

This is the way the pellet is supposed to be loaded into the gun.

Short, nose-heavy pellets like the otherwise good Crosman Premier have a remarkable tendency to flip skirt-up or backwards in the 2400KT’s steel breech.

Some pellets fit very tightly in the barrel during chambering. Domed pellets, even if tight, would usually slide straight in. But sharp-edged pellets such as wadcutters or hollowpoint noses with similar sharp edges would sometimes catch on the edge of the barrel as they were inserted. For easier pellets, backing the bolt up slightly and then pushing it forward again would smoothly seat the pellet. For pellets that tended to  catch an edge, I found that touching the top edge of the pellet skirt as the probe seated it into the barrel could help center the nose and provide a smoother insertion.

Trigger tips
The single-stage trigger on the 2400KT has very little travel, which I really like. It does not feel crisp out of the box. I think this is partly due to its heavy pull, but the release is positive and clean. The trigger-pull averaged just under 5.50 lbs. (or 5 lbs., 8 oz.) on the .177, and just over 5.50 lbs. on the .22. Although the difference was small, the heavier pull on the .22 was noticeable.

The 2400KT trigger is not crisp out of the box, but the release is clean and creep-free. The trigger-pull was on the heavy side at just under 5.50 lbs. (or 5 lbs., 8 oz.) on the .177, and just over 5.50 lbs. on the .22. If you order, be sure to include a trigger shoe. An adjustable overtravel screw helps the trigger feel crisper.

But guess what? This trigger is adjustable! The Custom Shop website won’t tell you. The included manual, which is actually for the Crosman 2240, doesn’t mention it. And you can’t tell by just examining the gun. But remove the shoulder stock, and there it is!

You adjust the trigger by turning the knurled dial to move the spring retainer up (increasing trigger-pull weight) or down (decreasing trigger-pull weight). I initially began adjusting this trigger in very small increments, but eventually turned it down all the way to the minimum spring tension setting. This resulted in a pull of 2.40 lbs. (2 lbs., 6 oz.) on the .177, which I actually found a little bit too light. On the .22, the low trigger-pull setting yielded almost exactly 3 lbs. This still seemed slightly heavy to me, and I wished that I could have dialed it a hair lower. However, this was still an improvement on an already-good trigger.

When B.B. checked trigger pulls on Crosman’s two CO2 match pistols, he got a range of 2 lbs., 14 oz. to 6 lbs., 12 oz. on the 2300T, and 2 lbs., 6 oz. to 5 lbs., 8 oz. on the 2300S (see Crosman’s 2300T, and Crosman 2300S target pistol). The 2400KT appears to have the same adjustable trigger. Sweet! The Crosman 2300T and 2300S manuals list adjustable trigger-pulls from 1 to 4 lbs.; but as you can see, the actual field measurements are heavier. Those manuals also include trigger adjustment instructions, and the 2300T manual might have been a better manual to include with the 2400KT than the 2240 manuals that came with my two guns. However, the trigger adjustment is simple and intuitive.

The Crosman 2400KT CO2 carbine comes with a 2240 manual that has a “2400 Custom Shop Airgun” sticker over it. Check the Spanish or French section of the manual, and the truth is revealed!

Neither the Custom Shop website nor the included manual hint at an adjustable trigger. You have to remove the shoulder stock to access it. Here it is!

Adjust the spring tension by turning the knurled dial to move the spring retainer up (increasing trigger-pull weight) or down (decreasing trigger-pull weight). On the left, the adjustment dial is at the factory setting. On the right, the dial is shown screwed downward to the lowest tension setting (and lightest trigger-pull).

The trigger includes an overtravel screw, which you can adjust to stop the trigger blade immediately after the hammer is released. This is a great addition to a target pistol. Like the trigger shoe, the overtravel screw does nothing to actually improve the trigger itself, but it does help the trigger feel crisper and cleaner by eliminating excess travel. I adjusted the overtravel screw in about one-and-a-half turns. This, combined with the lighter trigger-pull, makes for one nice feeling trigger! It’s still not quite as crisp as I would like, which is why I still recommend the trigger shoe. Overall, though, this trigger is a pleasure to shoot.

First shot
While researching for this blog, I repeatedly came across references to this family of pistols stating that the first shot on a new CO2 cartridge is always a dud. It’s not! I’m a manual reader, and the manual tells you that you need to cock and fire the gun once before actually loading a pellet in order to puncture the CO2 cylinder. During velocity testing, I found that the first “real” shot was usually much slower than subsequent shots, so I’ve gotten into the habit of firing off a second shot of CO2 before actually loading ammo. Finally, remember to put a drop of Crosman Pellgunoil on the tip of each CO2 cylinder when you install it to keep all those seals healthy and happy.

I’ve spent a lot of time telling you about the Crosman 2400KT CO2 carbine, without telling you anything about how it performs. In the next part, we’ll be looking at shots per fill and velocity. Prepare to be pleased, and — perhaps — mystified!
