Today we look at the HW 30S with a peep sight mounted. This will be a different sort of report, so grab your coffee cup and come along!
I say things like that (the report will be different) a lot, so what makes today different? Well, I shot the entire test angry and I didn’t do as well as I might have. Many times the rifle fired before I was ready and I am sure that didn’t help the groups any.
Why was I angry?
I was angry because when I went to mount the Weihrauch target peep sight I discovered it didn’t fit — not even close! Then the words of reader RidgeRunner started echoing in my mind and I was sure he had warned me of this.
So I went to Plan B which was to use the Mendoza sporting peep sight. It did fit, but when I sighted the rifle in at 10 meters it didn’t adjust low enough — not even close. Grrrrr!
The Mendoza sporting peep sight fit the rifle well but it had problems. I know it’s not all the way to the rear but it still couldn’t get close enough.
What problems with the sight?
For starters, the Mendoza sight doesn’t come back far enough on the rifle. So I end up peeking through the peephole and unconsciously trying to align the peephole with the front aperture and the target. That’s wrong of course, but unless that peephole is set a lot farther back it’s what’s going to happen.
Next the Mendoza sight doesn’t adjust low enough to center the shots in the bull. That is aggravating! When I shoot a scope I plan to miss the center of the bull because I want to preserve my aim point. But with a peep sight I can shoot the center out of the bull all day long, and I want to!
That set me off and the rest of the test was a struggle against my emotions. The rifle did fine. BB Pelletier didn’t.
I shot off a bag rest at 10 meters with the rifle rested directly on the bag. I was supposed to shoot 5-shot groups so I could shoot a lot of different pellets, but of course that went out the window on the first target.
JSB Exact Heavy
The first pellet tested was the 10.34-grain JSB Exact Heavy dome. They were one of the best pellets in that last accuracy test, and I wanted to establish a baseline for today. But I forgot about shooting 5-shot groups, so I shot 10 shots.
Ten JSB Exact Heavy pellets went into 0.463-inches at 10 meters. During this string the rifle fired twice before I was ready because the trigger release is set too light.
This group is actually pretty nice. I just knew I could have done better.
After shooting this group I realized that I wanted to shoot 5-shot groups, so that’s what I did from this point on.
JSB Exact 8.44-grain domes
The next pellet I tried was the 8.44-grain JSB Exact dome. The HW 30S put 5 of them in 0.416-inches at 10 meters. There was at least one shot that fired before I was ready.
I’m complaining, but do you notice that the dime will easily cover the group? The rifle is shooting fine. I’m the problem.
H&N Finale Match Heavy
I hadn’t shot any wadcutter pellets in the 30S and since I was using a peep sight I wanted to try some. So the next pellet I tested was the H&N Finale Match Heavy. Once again the rifle fired one time before I was ready. Five pellets made a 0.516-inch group at 10 meters. It is the largest group of the test and a dime still covers it almost completely.
RWS R10 Match Pistol
The next pellet I shot was the RWS R10 Match Pistol wadcutter. Five of them went into 0.418-inches at 10 meters. This is also not that bad, but I knew I could do better when I calmed down. This time the gun didn’t fire until I was ready.
It seems the rifle was shooting fine, but I was upset by the problems I was having with the peep sight and I felt that my mood was skewing the test. And there might have been a way to prove whether I was right. I shot a final five shots with the first pellet in the test — the pellet that grouped 10 shots into a group almost as small as the best 5-shot groups with other pellets.
This time I concentrated on not aligning the rear sight peephole with the front aperture and the target. In other words — just shooting like I was supposed to. The peep hole was so far from my eye that I had to make a conscious effort to do this, but I can do anything for five shots.
This time five JSB Exact Heavy pellets made a group measuring 0.233-inches between centers. This is not just the smallest group of the test, it is significantly smaller than all the other groups — and it came at the end of the shooting session when I should have been starting to tire. I believe it proves, or at least suggests strongly that the peep sight does work well on the HW 30S. But I have to admit, in the last test with a scope the rifle was shooting groups just as small with twice as many pellets. So today’s test does not thrill me about using a peep sight. Perhaps if I get a sight mounted correctly that will change.
I know for certain that I will increase the weight of the trigger let off. No more surprises for me!
Like I said at the beginning — today was a different day. I allowed myself to get angry and that threw me off somewhat. But I’m far from done. Next up will be a complete disassembly and a second lube tune, with a look at what the first tune accomplished without disassembly. After that I hope to install a Vortek PG3 SHO kit to compare to my lube tune. And after that, who knows?
