Benjamin Discovery accuracy?

[moorepower]

An A.O scope is much more important than a bubble level in my opinion. You can align the crosshairs with the horizon, but you can't estimate parallax.

On my first Disco the groups tightened up when I began to lube my pellets with the mix recommended by BB Pelletier ( Tom Gaylord ). Hoppes gun oil mixed with motor honey, I drip some on the sponge in an empty tin and roll them around. My new Disco seems to like them dry. The other thing that helped tighten groups was a lighter trigger return spring which I got by cutting down a spring from an ink pen. I move the rifle less when I have a lite trigger pull, but please be sure your rifle is safe if you change anything inside the trigger group.

My disco was my fist pcp. I will say that working on the trigger is what ultimately tightened my group. I used the three screw mod, less than $5 total, and a little time to make sure it is safe. That was all I needed.

I would recommend doing some trigger work before burning through more pellets.

Mine already has the 2 screw mod, and I don't believe that I'm having any bad shots because of the trigger.  If it ever starts posing a problem, instead of doing any more work to it I think I'd just replace it with a Mrod trigger.

About half down the page is a picture of the leade on a barrel that needed it taken down to feed the pellets right, many Crosman barrels need a little work.

I don't think mine has this problem because I don't notice any roughness when loading a pellet.  The FTT's do catch, but no other pellet that I've tried does that.  Actually, my 880 does the best with the pellets that are hardest to load.  I have been considering using some JB paste to clean it, though.  I may still take it apart to check the barrel, but I don't want to take it apart if I don't have to.  For one thing, I'm worried I may strip the breech screw like many others have (I've stripped enough screws before to know to be afraid of it).

An A.O scope is much more important than a bubble level in my opinion. You can align the crosshairs with the horizon, but you can't estimate parallax.

I may try an AO scope, but I've found that a lot of times when I think the scope is level, I look and can't even see the bubble because it's so far off to the side.  I never really had an issue with my Prowler while using a non-AO, but nevertheless I guess it's worth a shot.  I just dread having to rezero the scope I have on it right now, because the tracking on it is terrible (sometimes it moves a little bit with one click, sometimes it moves 2x as much, and sometimes it takes 3-4 shots before it settles down to where it's supposed to go.)


I believe that my accuracy issue at this point is the pellets I'm using have skirts that are slightly dented, and I believe if I get a new can with more uniform skirts they will do better.  In any case, I will have to order more pellets before I can try anything else.

I had worries about dented skirts. But many guys on here told me that the Disco has enough power that upon firing, the pressure of the air actually spreads the skirt out in the barrel and solves the dented issue.

I think misformed pellet heads are more concerning.

Good post.  I'm not a PCP shooter (yet ) but I would suggest carefully flaring the skirts of your JSB pellets.  You can use the cap of a Bic pen--the ones with the clear barrel.  I picked up about 40 fps with 13.4 gr AA pellets in my Diana 48 doing this.

Try tapping the turrent after each adjustment.   I use the plastic handle (non marring) of my pocket knife. This will help some scopes respond to the adjustments.

Good advice, Andy; I second that suggestion.  An officer at the local Sheriff's Department Range told me about that many years ago - and IT WORKS!

Thanks for the advice, I'll try that when I get to fine tune the scope.

Just placed my first order with Pyramyd Air.  I have 1500 15.9 JSBs and 500 18.1s supposed to be here Friday.  All total, it came in at $50.26 with $8 shipping and a 10% off code.

ETA:  Aaaannd it's already off to a bad start.  They put it on hold because they "couldn't verify billing address". What the heck is that supposed to mean?!?  The billing address was the same as the shipping address, except for the name.  Has anyone else had this issue?

[Edtampa]

On some web sites everything has to match. Name on credit card has to match the name on the shipping address. Not sure about Pyramid but I have had that happen before when I was shipping something to my girlfriend.

I'd call them in the morning and get it resolved.

[Night_Raider_]

I've already sent an email; hopefully they see it in time for it to be shipped tomorrow.  I've never had a problem before when ordering something, so I just find it a little strange that they would do something like that.  I wish I could just cancel the order and redo it, but I don't see that option anywhere.

I have used the bolt knob to straighten bent skirts just before loading.

I'll try that when I shoot the rest of the ones I have.  I didn't have a pen to use before, but I do happen to have a bolt handle laying around here somewhere .  Speaking of bolt handles, I'm going to have to blue loctite mine; it keeps spinning loose when I cock it and rubs the skin on my finger raw if I shoot too many at one sitting.  I forgot to do that the other night like I meant to.

Your shipping order may not get shipped when the name on the card and name on the address do not match, the purpose of that is, is when the bank computer reads it it must match. Some sites like Walmart have another option to choose a different shipping address, but not many have that option.

Hope you get it straightened out, also I use a ink pen sometimes to straighten out the skirts just remove or cut off enough of the writing end to allow it to fit correctly.

Good luck and happy shooting

If I were you, I would call them and verify your ordering information.  I had that happen with AgDepot and waited a week and nothing.  I finally called to straighten it out.  Just saying that if you are anxiously waiting...T

[Night_Raider_]

Alright, it now shows ready for shipping.  Customer service saw my email and responded back that "the order was approved and will begin the shipping process".  I'm sure glad that it got cleared up, but may have delayed shipping by a day.  I don't guess it really makes much of a difference, though.

My pellets came today, but naturally almost as soon as I sat down to shoot it started pouring.  I also picked up a can of Piranhas from Walmart, so I'm curious to see how those shoot.  I'll try to get some testing done tomorrow once the weather gets better.

WWWWhatttt!!!! You mean to tell me you dont have an umbrella and a flash light 

Ok, that's it, I am now taking Emergency donations for Umbrella's and flash light's, we can't have a situation like this happen again 

Well I guess due to the catastrophe (an event causing great and often sudden damage or suffering; a disaster.) I guess we will have to hope for a better outcome tomorrow!



Good luck, happy shooting
