Oh, boy, did BB ever get angry today! This report will interest BB more than the rest of you readers, I betcha. Read on to find out what got BB so flustered.

Getting ready

Last time I tested the FWB 600 I mounted the new front sight I received from Scott Pilkington. But then the rear sight was too low on even the highest adjustment. My groups were all low in the bull. 

I received lots of advice, including the fact that my rear sight seems too low for the FWB 600. I noted that the sight doesn’t say FWB anywhere so I think it’s aftermarket. I thought I had extra FWB peep sights but if I do I haven’t been able to find them. I have plenty of Diana peeps, but the only other FWB peep is mounted on my 300.

I spent an hour looking around for the peep before conceding I just didn’t have one. Whatever to do?

The BKL elevation riser

First I tried installing the BKL elevation riser that was on the rifle before. But now it made the shots land too high, no matter how low I adjusted the rear sight. 

AirForce to the rescue

Fortunately the AirForce Edge peep sight that I have has a huge amount of vertical adjustability which is just what I need. I have one and it was mounted on my HW 50S, but now it’s on the 600. The first shot hit the target on the bull I aimed at but low and to the right. After many more shots I had the rifle hitting close to the center of the bull, which is all I cared about. Since I would be testing different pellets there would be no attempt to adjust the rear sight any more.

The AirForce Edge peep sight is ideal for my problem! It adjusts up and down a lot, in addition to the fine click adjustments.

By the time I had the sight on the rifle I was very agitated, so I didn’t think my groups would be anything special, and they really aren’t for what we know this rifle can do. But they did demonstrate that I still have a tiny bit of discipline going for me.

The test

I shot the rifle off a sandbag rest at 10 meters. I shot 5-shot groups with each pellet. And for the most part I shot pellets I have tested before, so we have a baseline for comparison.

RWS R10 Match Heavy

My first group was five RWS R10 Match Heavy pellets. They went into a group that measured 0.091-inches between centers. That earns a silver Chackrum — the smallest comparison coin I have. In Part 3 five of the same pellet went into 0.078-inches and in Part 4 five made a 0.119-inch group. I think this pellet is very consistent in this rifle.

RWS R10 Match Pistol

Next to be tested was the RWS R10 Match Pistol pellet. The 600 put five of them into a 0.118-inch group at 10 meters. In Part 3 five of the same pellets made a 0.179-inch group and in Part four they went into 0.085-inches. So we are hanging in there but not as consistently with this pellet.

Qiang Yuan Training pellets

Next up were five Chinese Qiang Yuan Training pellets. Today the 600 put five into 0.109-inches at 10 meters. In Part 3 five made a 0.113-inch group and in Part four they went into 0.148-inches. This pellet is fairly stable in this rifle and today’s group is the best so far.

H&N Finale Match Light

The fourth pellet I tested was the H&N Finale Match Light. In Part 3 five went into a 0.102-inch group at 10 meters and in Part 4 five made a 0.101-inch group. That was great but today five made a 0.177-inch group at 10 meters. It was the largest group of the test and the only one to earn the silver three-cent piece called a trime for comparison.

H&N Finale Match Heavy

The last pellet I tested today was the H&N Finale Match Heavy pellet. I didn’t test this pellet in either Parts 3 or 4, so this is out first look at how it performs in the FWB 600. Five made a 0.094-inch group at 10 meters. It’s the second smallest group of the test and it earns the silver Chuckram comparison coin.

Where does today’s test leave us? Well the FWB 600 now has a rear sight that allows the groups to be centered in the bull. But it’s not an FWB rear sight. However, there is no evidence that the rear sight that came with the rifle was original, either. For now this sight will do.

I’m of the opinion that this 600 will outshoot my FWB 300. So that’s a test I would like to conduct. I think what I’d do is research the 300 and select what seems to be the most accurate pellet or maybe two pellets, then shoot several groups with each rifle with their most accurate pellets to see which one comes out on top. If you have a different idea or think I should add something, please let me know. Just as long as it’s shot at 10 meters with the right (target) sights and not with a scope!

Now — why am I more interested in the outcome of today’s test than you, as I said in the beginning? Because it demonstrates that even when I’m upset I can still calm down enough to hold a good group. That’s why I like this rifle so much. Because if the group is very large it has to be because of me.


The FWB 600 is proving to be the most accurate target air rifle I have ever tested. The trigger is certainly superb and it would seem that I can still shoot good enough to conduct a test with this rifle.
