Today is accuracy day for the Crosman 100 multi pump and I had to get out the trime! If you have been reading the blog for more than half a year, you know what that means. If not, you will.

The test

The test was at 10 meters indoors with the rifle resting on a sandbag rest. I shot 5-shot groups today because the 100 is a multi pump. I pumped 4 times for every shot. I said in the last report I was going to pump 5 times per shot, but after examining the velocity figures I felt 4 pumps were enough. Because I only shot 5-shot groups, I tried 4 different pellets, and when you see the results you’ll be glad that I did! Five shots are a fair indicator of accuracy. They are not as conclusive as 10 shots, but in a pinch they will do.


This rifle has been apart for an overhaul and refinishing, so there was no telling where the sights were. The first shot hit to the left (yes, RidgeRunner — my REAL left!) and a little below the target. As you know the rear sight on the 100 does not adjust in a precise manner. Two locking screws are loosened and the peep is slid in the direction you want the strike of the round to go. It’s fiddly and took me 5 shots to get on target.

Crosman Premier Lights

Because this is a Crosman rifle, I shot the first group with Crosman Premier light pellets. Not that anyone in the company today knows (or knew) anyone who worked there when the 100 was being manufactured, but I do it out of respect, I guess. Five Premier Lights went into a well-centered 0.556-inch group at 10 meters, which I thought was pretty nice.

Crosman Premier group
The Crosman 100 put 5 Crosman Premier Light pellets into 0.556-inches at 10 meters.

Sig Match Ballistic Alloy pellets

Next up were 5 Sig Match Ballistic Alloy pellets. There was no way I was going to adjust the sights for them, so they hit where they wanted to, which was a little high and to the right. Five pellets made a 0.565-inch group at 10 meters, and I was starting to have confidence in this rifle.

Sig Match group
The Sig Match Ballistic Alloy pellets made a group almost the same size as the Premiers — but in a different place. Five in 0.565-inches at 10 meters.

RWS Superdomes

The next pellet is one I didn’t test for velocity. The RWS Superdome is very often among the most accurate pellets in air rifles. It’s certainly worth consideration. This time the gamble paid off, as the model 100 put 5 Superdomes into a group measuring 0.443-inches between centers. Notice that it is also very nicely centered in the bull. When I saw it through my spotting scope I thought I had found the perfect pellet. But I said I would test 4 different pellet this time, and as you will soon see, I am glad that I did!

RWS Superdome group
Five RWS Superdome pellets went into 0.443-inches at 10 meters. The way the target paper tore makes the group appear larger. This is impressive. You would think this is the best pellet — right? Wait for it!

H&N Baracuda Match

Drum roll, please! The last pellet I tested was the H&N Baracuda Match that was in the velocity test. When I saw this group for the first time I knew it was time to get out the trime! For those who don’t know, I usually place an American dime in my pictures of my groups, so you get a sense of scale. The dime I use is somewhat of an icon and even has a story of its own. But sometimes I shoot a group so small that I need a smaller coin. I searched for a widow’s mite — the coin mentioned in the New Testament of the bible (Mark 12:42) — because it has the reputation of being very small. But real ones can be expensive and there is not a lot of agreement on which small bronze coin it actually was. So instead I settled on the American silver three-cent piece. Coin collectors sometimes call it the trime.

Five H&N Baracuda Match pellets went into 0.145 inches at 10 meters. This is as good as it gets, folks! I probably can’t do that well again in the next 100 targets — which suggests a test I might like to do. No, I won’t shoot 100 targets, but I’m not opposed to shooting 10. Then we could see whether this is a representative 5-shot group or just a random great one. This is the reason 10-shot groups are better when testing accuracy.

Baracuda Match group
This group is smaller than it appears because of the way the paper tore. Five H&N Baracuda Match pellets went into 0.145-inches at 10 meters.


This test turned out much better than I anticipated. The Crosman model 100 is quite accurate. The loading difficulty and faulty trigger are things I can work around for accuracy this good.


I’m proposing one final test, which would be 10 five-shot groups of H&N Baracuda Match pellets at 10 meters, which we can then compare to the last group of this test. That’s going to take an entire report to present and it’s going to take me a lot of time to do, so I will only do it if you really want me to. Otherwise, this is the final report.
