Sheridan Blue Streak: Part 4
by Tom Gaylord
Writing as B.B. Pelletier
My Sheridan Blue Streak dates back to 1978 when I bought it new.
This report covers:
- The test
- H&N Baracuda
- Crosman Premiers
- H&N Field Target Trophy
- H&N Baracuda
- Adjusting windage on a Sheridan Blue Streak
- 10-shot group
- Sights moved the wrong way
- Final group
Today I move back to 25 yards, to test the accuracy of the Sheridan Blue Streak for the last time. I used the information that was gathered from the accuracy test in Part 3 to select the pellets for today’s test.
I shot from 25 yards while seated with the rifle rested on a sandbag. I shot 5 shots at each target but one and I will explain about that one when we get to it. I pumped the rifle 4 times per shot for every shot in today’s test. I will comment on the sights as the report progresses, but when I started the sights were where they were for the 10-meter test in Part 3.
I told you in part 3 that the .20 caliber H&N Baracuda is a lighter medium-weight pellet, unlike all other caliber Baracudas. I shot it first because of that. I was back at 25 yards and I wanted to still be on target and roughly in the center of the bull. And I was!
Five Baracudas hit the bull at the right height, but slightly to the left of center. There were still two other pellets to shoot, so I left the sights where they were. The 5 pellets landed in a group that measures 0.71-inches between centers. Three of the pellets are in the same hole, with the other two some distance away.
The second pellet I tried was the tried-and-true Crosman Premier dome that’s no longer made. Both this Blue Streak and my Sheridan Supergrade like this pellet. In fact my Supergrade put 5 Premiers into 0.397-inches when I tested it a year ago. So I was hopeful, but had no idea this Blue Streak was about to do even better!
The Blue Streak put 5 Premier pellets into a group that measures 0.325-inches between centers at 25 yards! Now, that is some shooting! This group is also left of the center of the bull, though the elevation is right on.
Five obsolete Crosman Premier pellets went into 0.325-inches at 25 yards. This Blue Streak can shoot!
I want you to remember this group because something happened in a minute that changed the test. Just remember that old BB can shoot when things go his way.
H&N Field Target Trophy
The next pellet was the H&N Field Target Trophy that did so well at 10 meters in Part 3. I wondered what I would do after the Premiers had done so well. So I just put my head down and shot my best. I didn’t look at the target until I walked down to change it. If the group had no measurable size whatsoever, would you believe me that there were 5 shots in it? Well, there was no cause to worry.
The five pellets landed in an open group that measures 0.771-inches between centers. Of the three test pellets, this one shot the worst! It also landed to the left and slightly higher than the other two pellets. No worries there, though, because I wasn’t going to shoot it again.
After these three targets had been shot I wanted to shoot a 10-shot group with the most accurate pellet. On this day that was the Crosman Premier — no doubt about it.
I also wanted to refine the sight picture to hit the center of the bullseye, so I went to the Blue Streak manual that’s still online on the Pyramyd Air website. As you may know, the Sheridan rear sight adjusts in both directions. There is a screw in the center of the leaf for the vertical adjustment. It’s pretty obvious what you need to do. But the windage adjustment is a different matter.
Adjusting windage on a Sheridan Blue Streak
The rear sight leaf has a screw on either side. Both have to be turned to adjust the sight. But what do you do? That’s why I went to the manual. And, guess what? Whoever wrote this version of the manual didn’t know, either. Here is all the manual says about adjusting the rear sight on a Blue Streak.
Yeah — they didn’t know, either!
So I did a search and found people discussing Blue Streak rear sight adjustment on one of the forums. The guy told someone to loosen the screw on the side he wanted to move the sight toward and tighten the screw on the other side. If you want to move to sight to the right, loosen the screw on the right and tighten the screw on the left. My pellets were hitting to the left of center so I needed to move the sight to the right because you always move the rear sight in the direction you want the shots to move.
After adjusting the sight I started shooting the 10-shot group. By shot number 5 I noticed my hands were shaking. Was I really that stressed about this group? Then I felt it — a warning sign that my blood sugar was too low.
I inject insulin 5 times each day to control type one diabetes. I check my blood sugar level before doing this, plus I have to factor in any food I’m about to eat. After 8 years of doing this I have gotten pretty good at it, but every once in awhile I make a mistake. That’s what happened this time and my blood sugar was dropping too far. It starts with the shakes and then I feel super hungry. After that I start a cold sweat and within minutes I will black out. I don’t know what happens after that, because I have only gone that far twice, but I don’t think it’s good.
I persisted shooting, thinking I could just tough it out, which is what I always do and it never works. As the symptoms advanced the shakes got worse, so after shot seven I stopped shooting and treated my situation. Believe it or not, the fix is to eat a candy bar! What a disease!
It takes about an hour for the symptoms to go away, but I didn’t want to wait that long. After a 20-minute break I resumed shooting and shot the final three shots. This wasn’t going to be my best group.
When I saw it I was surprised it was as good as it is. Ten Premier pellets went into 0.942-inches between centers at 25 yards. It looks smaller than that to me, but that’s what the caliper says. HOWEVER…
Ten Premier pellets went into 0.942-inches at 25 yards. But the group went the wrong way!
Sights moved the wrong way
So much for listening to people on the forums! The good news is I can fix it, which is why I’m writing this here. From now on this will be a reminder to everyone who wants to adjust an original Blue or Silver Streak rear sight for windage.
To move the sight to the right, loosen the left screw and tighten the screw on the right. That pulls the rear sight leaf to the right. I watched the leaf move this second time and could actually see what it was doing. I knew how much the sight had moved the first time, so I doubled it and added a little extra. What I mean by that is how loose I made the left screw, which is what allows the sight to move to the right when I tighten the right screw. It was a guesstimate, but it was pretty close.
To check that the sight was adjusted correctly I fired a final group of 5 Premiers. I was still feeling bad and the group was almost as large as the 10-shot group, at 0.862-inches between centers, but it was now centered very well.
It’s not a tight group, but the Premiers are now hitting where I want. Five shots in 0.862-inches at 25 yards.
This series has been refreshing for me. I think a lot of you have enjoyed it, too. We took a rifle that was made as an inexpensive replacement for the Sheridan Supergrade and we showed that it is every bit as accurate and as powerful as that icon of American airguns.
I will now put the Blue Streak away with two pumps in the reservoir and the hammer uncocked.
