BSA Scorpion 1200 SE PCP air rifle: Part 2
by Tom Gaylord, a.k.a. B.B. Pelletier
We’re back to the BSA Scorpion 1200 SE. My hand has finally healed, and I can now work the Hill hand pump, but I stopped part of the way through the first fill and made the necessary changes to the carbon fiber tank hose, to attach BSA’s proprietary fill probe. I gave up because I just got tired of pumping! Those who encouraged me to do this from the beginning have won me over, I guess.
This PCP rifle takes a fill to 232 bar, which is 3,365 psi. We’ve looked at fill pressures for pneumatics a lot over the past month, and today we’ll see what this BSA rifle manages to do with its fill. The advertised number of shots is 25 per fill.
Because of the power potential of this rifle, I switched my backstop to the tough one blog reader Jim Contos made for me. If you want to read about this fine homemade quiet pellet trap that’s strong enough to stop the most powerful smallbore air rifle, here’s the link.
Familiarization with the magazine
After 10 minutes of trying (and failing) to load the 10-round spring-loaded magazine, I was prepared to blast BSA for creating a magazine that’s impossible to load. What we had, instead, was a B.B. who refused to learn new ways. The magazine loads easily once you do it the right way! I took a photo of the correct hold, so you won’t have the problems I did. Hold it like this and realize that BSA has designed this mag so the last pellet loaded holds the spring-tensioned drum in place until you’re ready to load the next pellet, and everything will be fine.
The magazine accepted all 3 of the pellets used in this test without a problem. They’re among the heaviest and longest .22-caliber pellets on the market, so I think you’ll be satisfied no matter what you try to shoot.
Pellet 1 — JSB Exact Heavy and the shot count
The 18.1-grain JSB Exact Jumbo Heavy pellet averaged 883 f.p.s. in the rifle. The velocity ranged from 875 to 888 f.p.s. over 25 shots. And 25 shots proved to be the limit, exactly as advertised. After shot 25, the next 5 pellets went this fast.
Clearly, the rifle has just fallen off the power curve but in slow motion. So there are actually 30 safe shots on a fill, and that equates to 3 full magazines. I’m so glad BSA publishes accurate figures for these things, as many other airgun companies seem to have no clue what’s right!
At the average velocity, this pellet produced 31.34 foot-pounds of muzzle energy. And I bet this pellet is also accurate, though that has to wait until I get out to the range, because this rifle is too loud for shooting inside the house. I took a risk by chronographing it for today’s report, but that’s as far as I’m willing to go.
Pellet 2 — H&N Baracuda
The second pellet I tested was the 21.3-grain H&N Baracuda Match. These are longer pellets that sometimes have difficulty feeding through rotary magazines like the BSA’s, but there was no problem today! They averaged 815 f.p.s. and ranged from 811 to 819 f.p.s. At the average velocity, they produced 31.42 foot-pounds of energy at the muzzle.
The Baracuda is another pellet that should prove very accurate in this rifle. They should be the best pellet at 50 yards, but that remains to be seen.
Pellet 3 — Eun Jin
The third and final pellet I tested was the 28.4-grain Eun Jin dome. This is a very long pellet and may be the longest that will work safely in the BSA magazine. But they did fit perfectly and had no hangups once I learned how to load the magazine correctly.
Eun Jins averaged 718 f.p.s in the test rifle. They ranged from a low of 713 to a high of 726 f.p.s. At the average velocity, they produced 32.52 foot-pounds of energy at the muzzle. In other rifles, these pellets have never been the most accurate at 50 yards, but they have often been accurate enough to use as hunting pellets. However, as close as H&N Baracudas are in power, I would choose the most accurate of the 2 pellets after we test them at distance.
The velocity remained very tight throughout the entire fill with all 3 pellets that were tested. That means BSA has balanced their valve to work with exactly the amount of air they recommend using. And the fact that they got exactly the number of powerful shots they advertised was a welcome bit of news. Also, 25 shots is a good number for a rifle in this power class.
Adjusting the trigger
I mentioned in the first report that I would be adjusting the trigger in this report. To do that, the action is removed from the stock. The sear is a direct-contact type, so care must be exercised to not get the engagement surfaces too small, or the trigger will be in danger of jumping off from a bump.
The owner’s manual is a single sheet of paper printed on both sides, but the instructions for adjusting the trigger are good and thorough.
The screw on the left adjusts the trigger-pull weight of the second stage. The nut and screw in the center adjusts the sear contact area and then locks in place. That adjustment affects the length of the second-stage pull. The screw under the trigger blade on the right adjusts the first stage and should not be touched, according to the manual.
I adjusted the trigger as light as it would go and set the sear as close as it would go and still be safe. The trigger still has significant creep in stage two, but it’s light and breaks at 2 lbs., 4 oz. I can work with it set this way.
50 yards next
Because of the rifle’s power, I’m going to skip the 25-yard test and go straight to 50 yards. If I’m successful, we should see accuracy that will override shooting at 25 yards, anyway. If I discover that’s the wrong way to do the test, I’ll change at the range and shoot at 25 yards first.
