All:
Finally got my Leapers 3x9-50 Mil-Dot scope in the mail and changed out the broken RWS scope for it. Zeroed it from about 8m then again at 13m (inside basement, late at night). Then shot a five string series starting at about 1700 lbs. This is what I got 0.375 ctc, would have been 0.25 ctc but I had a small flyer. I had front and rear sand bags for support. I did the Lower Link mod on the trigger mechanism a week ago and this really helps the accuracy since I do not have to pull so hard against my thumb behind the trigger now.
I highly recommend the low link mod (drill new 1/8" pivot point hole, 1/4" further out on the lower link) as mentioned in other posts on this forum.
If you have not used the Chairgun software, I highly recommend it too.
See pic if I can figure out how to post it.

Wow, that's some good shooting!!!
-
Thanks, now I have to put a level on the scope rails, put a 4ft level at 35 yards, then level the scope. I noticed yesterday that I have some kant issus and my groups at 35 yards are only 0.75" ctc.
Anyone know if the Benjamin Discovery has a choked barrel?
If not, who can choke it for me?
-
Do your self a favor and do one thing at a time . Get the chant out of the way first . I dough you have a barrel problem at this point . You have not cut the end off as of yet . Also you did not mention how long of a shoot count the 3/4 group was . Pay attention to your fill pressure and sweet spot and shoot count . Marvin

Thanks Marvin, it was a 5-shot string, my standard for testing.
As of yet I have not Chrony'd my shots, I will be doing that.
The crown, on 3x magnifier looks OK, but this is the first I have looked at in detail. Seems uniform width all the way around.
I think next will be a Super Sear to see if I can get the trigger pull even lighter.
But, as you say, one step at a time.
Thanks Marv.

My wife and I are back from Washington State, we saw Mt Rainier, The Beehive and Levenworth over a long weekend visit - worth going to if you get the chance.
I will probably be starting to work on the Discovery tomorrow to see what happens.

Hey TinBender, see the Discovery 0.22 Tuning Thread I created after this one for the tune results - I think everything workied out pretty well for me.
Scott

Yes Scott I did:)
Glad it went well sincerely. Did not know someone could post in some elses name. Learn something new every day. As a busted up old tinbender I would never have thought to do that.
To the person that has the savy to use my name " I bow at the ankles to you sir"

WoW you were in my neck of the woods.

Great place to live!
And go figure, Seatle was sunny and warm the whole time!
-
I just bought one although it has'nt arrived yet. What do you think about it. Do you like it or regrett the purchase?
Thanks. PS were under about 12" of snow right now:)
-
Great for the price. I like it a lot. You can lower the fill pressure and up the number of shots over a narrow pis-range if you tune it a bit ala. the BAM B-51 tune tips on the yellow forum.

Hey guys pardon the question but I'm a new guy to the adult airgun sport. I just orderd a Leapers 3x9-50 Mil-Dot scope for by rifle and forgot the mounts. Which ones shoud I get?
Bryan

Bryan,, no need to be too fussy bout mounts for the Disco. like on springers, (No recoil). Even though I dislike high mounts on any of my guns,, I would sgest you get some medium mounts at least for the Disco.,,, gives Ya more "finger room" to load pellets under the scope. I love my 22 Disco!! :D Most any inexpensive 11 mm/22 rimfire rings should do Ya just fine. You should be able to find em locally at Wally World or your local sporting goods store or gun shop. (two piece obviously). Good luck, & good shootin!! I may be away for awhile, Marvin,(mellowroadman) is a guy here that knows how to Disco.!!LOL!! Tim.
-
Thanks Buddy
-
This is what it looks like with medium mounts and 40 mm lens . So you will need to go at least to highs to get that 50 on it . Good luck Marvin
-
Thanks Marvin, The pic was very helpful.

Bryan,
So, did you buy the .17 or the .22 caliber rifle? Either way your going to really like it. Marvin is dead on about the high scope mounts for the 50mm. I have a 40mm scope on my rifle and it sits less than 1/8th of an inch above my rear site with the Beeman medium rings.
The first thing your going to want to do is shoot it. After that you might very well want to do a little polishing on the sear and trigger to sear linkage. There are several posts here regarding doing such and it will make for a much nicer trigger pull.
Be sure to come back and post some target shots!

Hey Neo, I bought the .22 with the Leapers 3x9-50 Mil-Dot scope. I also got the high mounts for it. If it's to unconfortable to shoot with the high mounts, I'll put the Leapers 40 on for size with the medium mounts. The rifle should arrive the 1st week of Jan. and I'm impatiently waiting. When I get her cleaned up and sighted in and I'll post the results.
Thanks

I got my Disco today (finally) along with my Leapers 3 - 9x50 scope. You guy's were right, to much scope for the rifle even with the high mounts. So I reckon I'll swap it out for the 40. Other then that my rifle looks great. I havn't shot it yet, I think I'll wait for the weekend.

Byran:
I am on the road in Huntsville, Al, this week and will get back to you on that with more detail. I used see-through high-mounts, but I just do not remember whoose they were.
