El Gamo 300
El Gamo 300 was a low-priced quality breakbarrel from the 1960s and ’70s.

Before I begin, blog reader HiveSeeker has asked me for some photography tips. Not that I’m a great picture-taker, but I do have some tips on how to photograph airguns. For starters, he wondered about photographing dark guns like his Winchester MP4. In the past, I’ve done several reports on airgun photography, but we may have enough new readers that it would be of interest, again. What do you think?

Okay, let’s get started. Today, we’re looking at the accuracy of the El Gamo 300.

This report covers:

• Poor man’s R7
• Trigger
• Firing behavior
• Accuracy
• First pellet
• Summary

A poor man’s R7
The El Gamo 300 was supposed to be my “poor man’s Beeman R7.” It was supposed to have the power and accuracy of the R7 (which is a modified HW 30S) at a cost that was far less. At the time, when the 300 was selling (the late 1970s), the R7 was sold with open sights, so the two airguns were comparable. The HW 30S still does has open sights today; so in that respect, the comparison can still be made.

As it turned out, the 300 is about 100 f.p.s. slower than an R7. The cocking is easier, but this rifle isn’t in the same power class, so any comparison suffers.

Adjustable trigger
Alas, the 300’s trigger is much simpler and only minimally adjustable, while the R7/30S both have the famous Rekord, which is one of the finest sporting airgun triggers of all time. I did try to adjust it, but the biggest thing that seemed to change was the length of the first-stage travel. The pull did drop, but only by a little. When the first-stage travel was shortened it did increase the length and creep of stage two; so I guess you could say it does adjust the pull to that extent, but the results were not very encouraging. It’s an acceptable trigger for an inexpensive spring rifle, but far below the Rekord for performance and adjustability.

One reason I wanted to get a 300 is because I believed it had the same action and trigger of the El Gamo 68 XP. That rifle’s trigger is very adjustable; and, while it gets unreliable when you take it down too light, it’s very crisp and positive when adjusted to a normal sporting level (3-5 lb. pull weight). The 300 trigger can be adjusted even lighter with safety, but it still retains some creep in stage two.

Firing behavior
The 300 is a buzzy gun. I could no doubt fix it with a little tuning, but right now the buzz is its most annoying feature. When this gun was new in the 1970s, nearly every air rifle felt the same and there was no basis for comparison. However, in the past 20 years, both airgun design and tuning tricks have improved so much that the vintage guns now suffer in comparison.

For today’s test, I shot this rifle at 10 meters from a rested position. I used the traditional artillery hold with the rifle rested on my off hand, back by the triggerguard. As you’ll recall from my earlier reports, I felt the rear sight notch was too narrow for the front blade. Well, when the target was illuminated by a 500-watt lamp, it was easy to see the whole front sight and some light on either side. That made aiming precise when I didn’t believe it could be.

The rifle cocked easily; and when the barrel closed, the detent locked it tight. One of our readers mentioned that breakbarrels with opposing chisels at the breech seem to lock up tighter and with more authority than do those whose chisel detent rides over a round pin. I have to mention that the 300 has the double chisel arrangement and the reader is right. When this barrel closes, it sounds like a bank vault.

Looking down at the open breech, we see the chisel lock (right) that engages the spring-loaded chisel detent on the baseblock. This arrangement makes the breech lock up more positively than if the chisel detent had to go over a round crosspin. That hole above the chisel lock is the air transfer port.

First pellet
The first pellet I tried was the RWS Hobby wadcutter. I used a 6 o’clock hold and squeezed off the first shot, which surprised me when I saw the pellet had hit the 10-ring almost in the center. After that, I just shot the next 9 rounds without looking again. When I looked after all 10 shots had been fired, I saw a nice round 0.588-inch group in the center of the bull. That was a good start!

Not only is this 0.588-inch group of 10 Hobbys nice and round, it’s also centered in the bull. That makes it appear even better than it is. This is the best group the El Gamo 300 shot at 10 meters.

Next, I shot 10 Air Arms Falcons. The first shot hit the 9 ring, and I didn’t have to look again until it was all over. Ten shots landed in 0.629 inches, but 9 of them were in 0.41 inches. While this group is slightly larger than the Hobbys, I would say the Falcons are probably more accurate, just based on those 9 tight shots.

This group of 10 Air Arms Falcon pellets looks amazing, though at 0.629 inches between centers it’s larger than the Hobby group. Without that one pellet at the bottom, there are 9 in 0.41 inches.

The last pellet I tested was the 7.9-grain Crosman Premier lite. I saw the first shot go into the 8-ring so I stopped looking until it was over. This time, though, the pellets spread out more, and the group measures 0.771 inches between centers. From the open appearance of this group, I can tell that Premier lites are not the best pellet for the El Gamo 300.

Crosman Premier lites scattered more than the other two pellets. Ten made this 0.771-inch group. The group looks larger than it really is because the pellet on the right tore the target wider than where it penetrated.

The El Gamo 300 is not a poor man’s R7. It is what it is — a nice, inexpensive spring rifle that offers a lot of value for the price. Even today, when the used guns sell for $50-100, they’re still a bargain. But they’re not in the same class as a CZ Slavia 630/631, which really is a poor man’s R7.

I’ve been fortunate to be able to test several air rifles in this same vintage class over the past few years. Some of them, like the Diana 25 with the ball-bearing sear, are superlative airguns that withstand the test of time. Their very design makes them perform at a higher level than most guns. Others, such as the Falke model 70, promise the moon but fail to deliver. This El Gamo 300 is closer to the latter guns, although its low price does make it an ideal candidate for home gunsmithing for the careful hobbyist.

No doubt the 300 can be modified and tuned to be a wonderful air rifle; and when it is, it’ll have the accuracy needed to carry it off. But there are other airguns that are inherently nice just as they come from the factory. A 300 is probably the cheaper way to go, but expect to spend some time and sweat equity to turn it into what you really want.
