Fitting a Scope to a 300S and 601.

[zooma]

I have found a problem with fitting this sight to my 300S.

As I "settle" on the cheekpiece of the rifle I see the cross hairs in the sight moving up and down, as well as left and right with every slight movement of the head.

I believe this is called parrallex, and there is no adjustment for this on the Whitetail 1.5-5 x 20mm, so it looks like I need to find a sight more suited to the closer distance of 10 metres, or find one that can have it's parrallex adjusted for use at this relatvely short distance.

Perhaps this is the job of the "distance" ring on a scope when fitted ?

The air rifle Running Boar shooters must have found suitable scopes to work at this distance - any ideas what works best at 10 metres?

I shoot a FWB 300s SU at 20m bench rest with a Bushnell 4-12x40 scope. I took me a while to find the right scope for the rifle and I may not have found the perfect one yet, BUT tonight I had to shoot 4 cards. 95.96.96.97.

Put it this way the rifle shoots better than me.

I have found with all my bushnell scopes there seems to be a sweet spot, it takes a while to find but when you do its worth the time you have Spent.

It's still possible to adjust the parallax free distance. 10m is close range, but it should be possible to significantly reduce the parallax error you are seeing, if not fully remove it.

Here's a link showing what is involved. It's one of those jobs that is easier to do than write an explanation of.

Thanks for the link.

The scope I have does not have a removeable end section to hold the front lens - only the threaded lens retaining ring inside the scope outer case, so I am guessing this will make it a whole lot harder to adjust as some form or spacer will also have to be inserted behind the lens.

I will take a look and see how practical it wil be to do this. Maybe I have the wrong scope and it would be better to sell it or exchange it for something more suited or more easilly corrected for 10 metre use?

That 601 mount as I mentioned earlie has a somewhat 'Sportsmatch' appearance to it - have you tried asking Sportsmatch if it was something they might have made?

I sure I reparallaxed one of these and it had a "normal" locking ring on the front objective. It was probably 10+ years ago, so possibly a Mk1 version of the scope?

It might be worth asking the question in the regular "Airgun Section" to see if anyone has recent experience/knowledge. Don't give up on it yet.

[Bing!]

Have you thought about putting out a shout for the folks with access to milling machines etc? They may be able to modify something for you.


Bing!

I have a running target 601 all I have is a set of very high scope rings. the loading port just barely clears the scope. I got the rifle second hand and it came with the scope and rings. The scope is a normal leopold 4 power with modified posts for running target

Nice!

I have a C60 now but it will stay in its native form

As its not in my "interest " I never bothered to look at this thread in 2012, but for some reason have just read it (only 4 years late!), as a 10 mt Running boar shooter back in the old days (I sold my RB Walther LGR to Rockdrill a few years back, do you still have it?) the 10 mt scope correction for paralax was always a problem, many did not understand and just put up with it, us perfectionists corrected it! The simple way was with a 0.1 diopter lens in the front of the scope, clamped by the front ring and put in between a couple of "o" rings.

And before you say there is no such thing as a .1 diopter lens, we had then (many years ago!) a tame lens grinder who also had a stock of plain lens's, he would go through them and often find one with 0.1 tolerance which he would put to one side for us, and next time we wanted one he had a stock from which to draw and grind the dia to fit our scopes.

The Walther LGR Running boar was suberb, a proper factory rifle built in very small numbers, it used a thumbhole stock and wooden buttplate so it slid in nicely. I used a fixed 4 power scope from Nickel (or something like that), with a single post (you needed a mortgage to buy the twin post RB scopes), 4 power was the max allowed in the rules for 10 mts, and the dia was limited as well.

The target was a scaled down 50 mt Running boar, affectionately called "running rat" by the officianado's, I still have one, they are a little work of art, now its boring round targets (politically incorrect in the ISSF to shoot even paper animals!), its a very difficult event, but great fun.

Good shooting

Very interesting post again, Robin. Running boar has long fascinated me but my experience extends only to staring wide eyed at the Walthers, Original etc Moving Target rifles in John Walters "The Airgun Book". They are look superb, the Walther in particular.

In a later version of the book a FWB C60 moving target is depicted with a scope held by a strange, large diameter front mount which sits well forward and clasps the bell of the scope. The rear mount looks pretty standard, if high, and clasps the scope tube in front of the turrets. BOTH MOUNTS ARE FIXED TO THE BARREL.

The loading latch on this gun looks shorter than that on a standard 600, though.

I know nothing of the C60 or 600 RB's, none were around when I shot it, for my Walther I had a very high alloy mount machined up by a mate that I used to clear the loading port on the LGR, but more importantly to get an upright head position which helped balance and quick sight location, no problem as the rifle had an adjustable cheek piece which could also be set up high. All that was vital as you started from the rifle butt held to the hip and could not move until the target appeared, and then had 5 secs on a slow run or 2.5 on a fast run, very demanding, very technical, but great fun.

I also used a 12 times scope but the ISSF changed the rules whilst I was doing it to limit to 4 times and limit the lens size as they thought the bigger ones gave a bad image of the sport because they looked too much like sniper rifles!! And they also changed the 10 mt picture boar (running rat) target to a boring dot also for OTT PC reasons. The ISSF have worked hard over the years to wreck our sport and are still doing it!

I have pictures of my rifle, scopes, and mount but I don't have a means of posting on here if you PM with your email I'll send some to you.

Have Fun,
Robin

Well, here's the Feinwerkbau's take on the RT/RB sport. The scope is a Leupold M8 with a custom reticle (a single vertical line with a dot in the middle) factory fitted with a Premier booster/reticle which has additional vertical lines with dots in the middle. The middle dot is adjustable by Leupold's own towers and the side dots in the Premier unit are independently adjusted by the four towers in that unit. Note that the Premier unit is attached slightly canted in regard of the Leupold scope to compensate for the cant the rifle sets on the shooter's position. So, when you lift the rifle, all three lines are vertical, but if you put it on a bench rest, the lines are canted to the right. There also is no horizontal lines whatsoever

G'day,

While browsing ads for used air rifles I found this FWB 601 for sale over here. I remembered that there was this thread about mounts for FWBs and Zooma's comment: "It is great to see this thread is still alive after 5 years - and hopefully the wait will be worth it if you have un-earthed a mount that will fit the 601."

Hopefully this will be of interest - if my rather basic computer skills work: http://www.melbournefirearms.com.au/images/17628.jpg

and: http://www.melbournefirearms.com.au/images/17628b.jpg

It appears that the scope mount has been tapped into the side of the barrel mount at the breech and is shaped to allow the breech to rotate and close. I don't have a clue as to who made the mount, but could try to find out if someone wished to know.
