Received a Crosman vigilante from wllm995 to have some work done to it this is my first time working on one of these pistols. He asked if I could bring up the fps a bit more and rightfully so, when I received it and ran it over the chrony it was shooting 391fps with a RWS 8.3gr pellet no were near the suggested out of the box 465fps. :shock: I don’t know why they almost always put these false claims on the box. :?

So I dismantled the vigilante and opened up the valve and since it’s not my gun I only cut one and halve coils off the valve spring I didn’t want to cut more in fear that the valve might leak, then opened up the hammer spring to give it a little more tension on the hammer strike, and also compressed the trigger spring to give it a lighter trigger feel. And then I did some stippling to the gripes to finish it off, now the gun shoot’s and feels much better.

Here are the results from the chrony:
Before mod’s: RWS = 8.3gr 391fps to 396fps and RWS = 6.9gr 418fps to 429fps
After mod’s: RWS = 8.3gr = 425fps to 430fps and RWS = 6.9gr = 445fps to 455fps


Image

Gun opened up.
Image

before stippling:
very plain and way to smooth for good off hand shooting.
Image
Image
Image

After stippling:
much better feel and grip.
Image
Image
Image

finished back together and shipped, hope you like it D :wink:

Great work on the tune up!

I wish they made it all metal. I see a lot of plastic.

Wow!

Very happy with how it turned out.

Looking forward to getting it into my hands and seeing how it shoots now.


:D

Thanks TH :wink:

yes thats for sure :( just the main body and the obvious internals are metal. its pretty light and if you use it as a single action its pretty accurate. 8)

Edit: sorry made a little mistake, don't know much about the gun like i said and just did a little more research on it and it says, 465 fps w/steel BBs
435 fps w/lead pellets but even still it wasn't shooting 435fps with pellets :( . So i didn't even realize it shot bb's :oops: I'll have to ask wllm995 to test the bb's fps on it now, thats if he uses bb's. :wink:

I wouldn't bother with the bb's, it will ruin the rifling over time.

But one or two to chrony for the sake of curiosity wouldn't do any damage lol...

Nice Ace! I like the Stippling. How did you to it?

Wllm995,

Take a pellet and push it through the rotary mag,
Take that same pellet and then place it in the barrel.
What you should notice is a problem.
Fix this problem and should gain about 30 fps and your
Groups over 10 yards will cut in half.
-this is the best mod for this pistol if
You didn't want to go inside of it.

Reaper

Reaper: say again, please; there seems to be a missing link.

yes please explain, :?
if what i think your trying to say is almost what i had told wllm995 in a pm after finishing his pistol, and that was to seat the pellets a little further into the mag therefor increasing the velocity a little more. that was the co2 has less work of trying to pushing the pellet through the mag to get to the barrel. :wink:

I don't think that this is a secret:

Reaper:

We'll if u look inside the holes on your mags you will see little rails, and the hole tapers near the front of the mag.
I polish these rails out and make a bevel angle so the transfer port reads the mag chamber better. The factory mags swage the pellet so small that it barely bites the rifling on its way down the barrel resulting in loss of pressure( velocity ) and loose groups.

Well you guys are all getting warm.
It's not about pushing the pellet forward a
Couple mm for better gas expansion it's about
Polishing out the mag chambers to "fit" the pellet.
If you take the pellet an push it all the way through
The mag you will notice it actually Swages the pellet
Making it to small to properly fit he rifling. Just think your
JSB's made it all that way to you just to have you deform them
In the magazine.

Polish the chamber guide rails flush and bevel the edge so that the transfer port
Reads the cylinder better.

Sorry Murray no link this is from memory and chrony.

Cheers,

Reaper

I get your point reaper this is due to the fact that this pistol also shoots bb's, the tapering is so that the bb's don't slide down and out the barrel, but act's as restriction for pellets :wink:
your suggestion would be a good idea if strictly shooting pellets. 8)

I recently bought a referbished Vigilante from "Scopes and Ammo". It came with two rotary mags one front loading pellet mag and one totally different design for specificaly rear loading BB'S. But I would only shoot lead BB's due to the rifeling. The pellet mag needs the mod bad, it is super tight.

[quote="Ace"] the tapering is so that the bb's don't slide down and out the barrel, but act's as restriction for pellets :wink:

I don't see how the pellet mag has anything to with the bb mag?
Plus the bb mag has it's own way to holding bb which is unrelated
To the pellet mag.

There are other mods that you could have considered when the pistol was sent to you

These are JUST power mods as there are a dozen other mods to improve feel and accuracy.

Just to name a few:

- Polish out mag rails for less friction
-bevel back of mag to read cylinder better and seal better
-drill out rear port to match ID of the pellet skirt for increased flow
-drill out valve ports for better flow
-cut up to 2 coils off the spring and straighten edges
-Polish hammer and friction surfaces
- shim the hammer spring
- open up the spring
-Stretch Port spring to seal better with the mag chamber
- push back barrel and secure to seal better with mag chambers.

I have a standard 357 shooting 8.44gr @ 494 FPS average over 6 shoots.

Well thanks for sharing the tips reaper, this was my first time seeing and working on one.
I was only sent one mag with the pistol i didn't know there were seperate mags for bb's, :shock: and like I said before I didn't even realize till after the mod's were done that is shot bb's lol..... also sinse this was not my pistol I didn't want to tinker to much with it and end up with a leaky pistol, something tells me wllm995 woundent want that kind of news :lol: :wink:

Notheing wrong with gathering and gaining knowledge as we go along. 8)
