It’s been awhile since we looked at the FWB 600. In Part 3 which ran early last December I discovered that the rifle had a Running Target front sight. That made the rifle shoot 5 inches below the aim point when the rear sight was adjusted as high as it would go. I had to put the rear sight up on a BKL riser block to raise the impact near the bullseye, but that made the rifle shoot too high with the rear sight adjusted as low as it would go. Today I see if I can correct that. You’re going to see some good shooting today!

FWB 600 front sight
This is a front sight for a running target rifle. This is the sight that came with the rifle when I got it. The regular 10 meter front sight would be down level with the silver muzzle cap.

FWB 600 rear sight riser
The BKL rear sight riser fits the FWB 600.This is what I had to do to get the pellets up in the target with that tall front sight.

I contacted Scott Pilkington from whom I got the rifle and he agreed that the front sight I had wasn’t the right one for the rifle. So we swapped and he sent me a replacement front sight.

Where we were

In Part Three I shot five-shot groups with six different pellets. In all that I got four gold dollar groups that were smaller than 0.15-inches between centers. The other two groups were silver trimes — groups smaller than 0.2-inches between centers. I told you then that it was the first time I had even shot a 10 meter rifle and gotten no groups that used a dime (groups that measure 0.20-inches or larger between centers) for comparison.

Where we are

Today I shot five 5-shot groups, using all but one of the pellets from the Part Three test. Four groups were gold dollar groups and one was a Indian silver Chakram — a group smaller than one-tenth inches between centers.


Yes, there is a however today. This time I couldn’t get the groups high enough to hit the center of the target. The rear sight was adjusted as high as it goes and the groups are still too low. Oh, well — that means I have to change something and shoot it again. Oooookay — if I gotta!

The test

I shot from 10 meters off a sandbag rest. I used the target sights that come with the rifle. I shot 5-shot groups.

Sight in

I sighted in with Qiang Yuan Training pellets. The first two shots were about 5 inches low and off to the right. So I cranked in a lot of elevation and, after three more shots, ran out of vertical adjustment. All my groups will be low today.

Qiang Yuan Training pellets

The FWB 600 put five Qiang Yuan Training pellets into a group that measures 0.148-inches between centers.

The trigger

I have to comment on the 600’s trigger. It is superb! It’s better than the trigger on my FWB 300S, and that’s saying a lot. The beauty of the 600 trigger is I can hold at stage two and wait until the bull is perfectly centered and then wish off the shot. This trigger is as nice as the one on my TX200 Mark III, now that I have adjusted it.

H&N Finale Match Light

Next to be tested were five H&N Finale Match Light pellets. The group they made looks larger than it is. There is a large tear at the bottom of the group that was not made by a pellet. The actual group is little more than two pellet holes wide. It measures 0.101-inches between centers.

I enlarged this image to show what I’m talking about. That large triangular hole under the two upper pellet holes is just a tear in the paper. Examination of the back of the target reveals it. Only the two upper holes constitute the 5-shot group that measures 0.101-inches between centers.

RWS R10 Match Heavy

Okay, the RWS R10 Match Heavy pellet  gave us a 0.078-inch group in Part Three. That’s good for a silver Chakram today, but I wasn’t using that comparison coin back then. It was the smallest group in the Part Three test.

Today five of the same pellets went into a group that measures 0.119-inches between centers. Not as small as last time and you can thank BB for that — not the rifle.

Sig Match Ballistic Alloy

The next pellet I tested was the Sig Match Ballistic Alloy pellet. In Part Three they were the second most accurate, producing a group that measured 0.09-inches between centers. The comparison coin would have been a Chakram if I had been using them. Today five of them went into 0.127-inches at 10 meters. It was a very good group — just not as good as before.

RWS R10 Match Pistol

The last pellet I tested today was the RWS R10 Match Pistol pellet. In Part Three five of them went into 0.179-inches at 10 meter. Today they cut that in less than half, going intro 0.085-inches at 10 meters This is the smallest group of today’s test and the only one that’s smaller than one-tenth inch.

What got me writing about the FWB 600 was the Haenel 312 that I worked on yesterday. I wondered how it would compare to a world class 10-meter rifle and that’s when I discovered that I hadn’t reported on the new lower front sight on this FWB 600. And even with what I have done here I’m still not finished.

I want to get those pellets hitting the center of the bull — at least with some of the pellets. That’s what these rifles are for, and I don’t want to miss it. At this point it seems like I have to reinstall the BKL riser to do that. We shall see.


We talk a lot about the FWB 300. Well, I’m here to tell you that the 600-series single stroke pneumatics (models 600, 601, 602 and 603) are every bit as accurate and maybe even moreso. I know some of you own these rifles. Time to speak up!
