FWB 300S

[Jason_Garvin]

Hi there,

I have had three of the high end models that look and shoot new.  My models with the heavy weight on the end none would smack the rear of the sled when shooting.  With my trigger hand I reach up with my thumb and push the action forward after each shot.  My brother has a mini and it slaps the rear probably due to lack of muzzle weight. 

You can pull the stock and oil the two pins on the front end, if I remember right it is one large dowel on the rear.  There are some good instructions out there on tear downs they aren't to difficult.

Take care,

💀

I watched both my 300S closely during the firing cycle and both of them bounce back but before they travel all the way back to a stop the forward recoil pulls the action forward on the loose gun, even locking it in about 50% of cases (shooting JSB 8.44 pellets). The less loose action does not travel so easily forward but rather comes to a stop from when it was going back, thus eliminating really only the rear (first) recoil.  As i suspected, something is wrong with it and i hope it only needs lubrication.

Thanks for all your help, i will keep you posted and also post a few more pics after i am done getting acquainted with them.

After firing, the action on mine slides forward smoothly and then locks in place.

Have any of you experimented with front sight inserts like these..

I shot several groups and tried 7 different pellets, will post some pictures later.

I also took the stock off the one that wasnt sliding properly. I have narrowed it down to the rear stock screw. When it is loosened 180degrees from being fully and lightly tightened, the recoil-less system slides freely just as the other rifle's does. But when the screw isnt properly tightened there is a slight give in the action-stock connection in the back and you can feel the play. I'll investigate further, but the isse lies there in the rear screw/threaded metal connection. I'll take pictures too if i remember.

I prefer the clear sights with a dark ring myself.  I am thinking around the 3.3 size.  There is a guy in Canada on eBay that will have them with cheap pricing.

The ebay link is a seller from Canada, chances are it is the same guy. He has metal sights too.

What is the optimal position of the rear sight to the eye? I am not sure i know how to use these sights properly and looking through them as intended.

Pic2 is of all the pellets tested.

Pic3 is five 5 shot groups shot with corresponding pellets.

Pic5 is 10 shot groups of what i thought were more accurate pellets.

Pic 7 is 10 shot groups of some more pellets. 

I wasn't really trying as hard as i could have, i was more interested in getting some pellets down the barrel and seeing how they would group.  JSB 8.4 and RWS Meisters and Crosman brown box 7.something pellets seemed to be most accurate.  I will be repeating the test with just those three pellets and will shoot more 10 shot groups.

Many shooters report that FWB 300's have a tight bore and shoot smaller head size JSB Exacts -- 4.50 or 4.51 -- very well.

"What is the optimal position of the rear sight to the eye? I am not sure i know how to use these sights properly and looking through them as intended."

As close as you can get without getting smacked by the action. Maybe 1 1/2". You don't look at the rear sight. You look through it. Because of the small aperture in the rear, both the front sight and target will be in focus. These sights are designed for round targets. Get a front sight opening or adjust your target size so that there is a narrow white ring/ margin around your target.

[stija]

I found out that Crosman's fit really snug, and i mean really snug. The others fit in more easily.

Thank you for that advice on using the sights. I was using them wrong and had about 6"+ between my eye and rear sight. When i retest JSB, Crosmam and RWS pellets i will try and use the sights correctly. I did instinctively try to position my eye so that i would end up with a white (target paper) ring around my target, but adjusting the front ring size or target size makes more sense

Congrats on the new rifles,
 
  Crossman will be too tight and slow as are the rws meisterkugeln offerings, which can be felt in the recoil alone.  The RWS Basic wadcutter is a bargain at the right place and will out shoot them, and many others, at 10m and provide at least 575 fps.  At 10- 20m it will be hard to beat H&N match rifle wadcutters, they are excellent and shoot to spec.  I haven't tried those excite pellets in mine yet, though I have some.  For 20m+ JSB RS, 7.3 shoot faster than all and are accurate like their other domed exact/express offerings. These are all 4.52. You will set the sights up so that you see small concentric rings off light, around the front sight housing to begin with and all the way down to around the black bullseye, with the clear front around it.  You don't have to go too small with the front, experienced shooters don't, as center is center and a larger one is more relaxing to the eye. Do enjoy.

I have one and I really love shooting it, it is just so steady.  Nothing else is like it!  It's quiet, smooth to operate and when I shoot, I just keep looking thru the peepsight and see that the point of aim doesn't change during the shot cycle.  It is a much smoother shooter than the Air Arms 200T PCP target rifle, IMO.  The "Swiss watch" simile mentioned above is right on, these are gorgeous machines.

My lovely gun here was used well by a local gal to shoot competitively with her father back in the late 1970s and early eighties.  I am very fortunate to be its third owner.

You made a great find!  Please fix them up and free up their potential.

If you find that the one bangs its sled against the stop during the firing cycle, and the sled starts in the full forward position, the spring is too powerful.  Please replace the spring with something that won't ruin your hardware in the long run.  You might check if someone placed a spacer to get more compression out of the spring and if so, removing it may bring the power level down. 

Enjoy!

Thanks for the advice guys, i appreciate it.

Neither rifle bangs it's sled but i noticed that one of the sleds binds somewhat when the rear stock screw is fully tightened. If tightened and then loosened by 180degrees the sled slides freely. I'll have to investigate more what is going on there. So far there seems nothing else to fix on them since the person i bought them from resealed them and i can see the seals, one is green and one blue.

I am thinking about sanding down the lacquer off the stocks and then treating it with pure tung oil, after appropriately preparing and sanding the wood of course. I'll definitely do that to the one i decide to keep, which so far seems to be the one with the stock double spring configuration and worse aesthetics and wood.

    yes looking thru the site after the shot is following thru and I shot almost one hole groups at 25 yds with mine using that style

[stija]

I am assuming that is using open/peep sights mista meener? I havent yet been able to shoot that well but i also just realized i wasn't using the sights properly.

Soon to come more pellet tests with properly set up sights, most likely tomorrow.

[stija]

I tinkered with the one whose rail was binding and in the end i had to loosen the rear stock bolt about 50 degrees after it was tightened snug. I can barely feel the play in action, up and down, but it's because i know about it. Rifle shoots superbly now that i have followed advice on proper sight placement.

The first two were sighters. The fifth pellet expanded the second group, but I'm definitely capable of shooting ragged holes at 18yds, and i wasnt really trying either. Shot with JSB 7.7 pellets with front rested on bag and my elbows on the shooting table, as usual. 

I didn't have much time today to shoot but i had to experiment a little with it after i helped it slide freely. This rifle is the one with the JM kit instead of OEM double spring setup.  It sounds a bit more metallic or sproingy than he OEM setup which sounds like a quiet pcp rifle.

[stija]

I let a few pellets fly today at 16yds rested on the bag, no hand. Rear elbows on table and no rear bag.  This was shot with the oem spring setup rifle, the other is just as accurate but sounds a bit sproingy. The ease with which these shoot is unbelievable. I was shooting my break barrel before it and the difference is night and day. Shot with JSB 8.44gr.

Now you're properly hooked. I have a Walther LGR SSP 10 meter gun that has greater perceived recoil than the 300s! It is also a beast to cock compared to the FWB. The fun thing with the 300s is that you know a lot is happening when you pull the trigger, but the only thing you notice is a brand new hole in your target.

Stocks off, give the metal works a good cleaning with particular attention to the sled mechanism.  If you see any scuff marks on the wood, something is binding to keep the mechanism from sliding freely.  Shave the wood scuff marks a bit to make it move completely freely and you should be good.

Mine is so smooth that I have shot groups at 50' that rival the test target that FWB sent along with the rifle.

Mine Like H&N Finale Rifle Match 4.50 or 4.51 head size the best.  4.50 is what i use most.

25 consecutive 10 shot groups that were all 1 hole groups with a maximum size of 0.400" center-to-centsr was my last campaign to get it zeroed and tinkered with.  (didn't need much)

By the way,  sometime ago, I tested over 40 different pellets in both my RWS54 and FWB300.  The data are here on the site somewhere, if you want to hunt for it.  This is how I got to the H&N Rifle Match Finale pellets.
