back to daily briefing


What happens when something needs service?

Well, I got an e-mail from Bob this week. Bob owns a Barnes Pneumatic Chaparral 25 Pistol. Bob drains chest high 6,000 psi Nitrogen tanks with said Chaparral Pistol. Bob has his own pistol play world where he enjoys his semi-retirement. Take a look later... Bob buys #3 buckshot from Hornady in five POUND boxes (that's 1,477 ball per box) ... and has a standing order at the local gun shop for a couple of boxes a week!

Bob either shoots a heck of alot ... or he really, really likes boxes of buckshot. ;?)

So, Bob's mail tells me the pistol is leaking alittle down the barrel when he fills it. We e-mail back and forth for details. I give him some "do this" type of things to check. Eliminate things like "is it plugged in?" ... ;?) ... and say ... send it up here.

FedEx drops it here the next day. I tear it down within the hour. It's a V-Twin series product. Made to be serviced. Made for efficient assembly and disassembly.

Most people are afraid to use the guns ... afraid they'll get all crappy, scratched, worn down. Want to see a crappy old worn out Barnes pistol as it came in? Here ya go ...

Yes ... I was appalled too ... `;?)

The service look-see revealed a failed secondary O ring on the internal firing valve. It left the gun leak above 1,000 psi during fill. I replaced it with a new composition ring I like better now. I proceeded to look thru the entire pistol ... knowing this Barnes had been shot more than any other PCP I'd ever placed in the field.

It was great. Rifling crisp and clean. Everything tight. Wood just glowed. Finish was great. Tiny spider web scratches on the polished billet here and there from handling and changing scopes, etc. I buffed the receiver since it was off.

I'd declare the gun to be too close to new condition to tell any difference. I reassembled all. Filled it. Took a pistol scope already on simple coin screw clamps from Wally World ... clamped it on.


That's the first three #3 buckshot after reassembly. Simple 4X scope - grabbed at random from a hard case of scopes and clamped on. Not too bad.

I have a new 25 caliber 31.5 grain slug. I clicked the scope over and down, and sent a few new slugs down the barrel. That's 3@12 yards.

There's a shop card of the string of the new slugs from a fill, as the pistol was set up. This is not necessarily "floored" ... it's the way it came in. For match shooting, this would tell me to fill to about 2,900 and shoot six for the real "cream" of this string at this setting.

Today, having these new 32 slugs for my Victory, Heritage, Appaloosa, Ranger customers. (That qualifies as service too ... continued development after the sale). I'd sent a few slugs out for testing. I remembered that the Nautilus was cased ... and a few minutes with shop ledgers verified that the new slug (as sent out) should be about right for the Nautilus as well!

I actually found it ... ;?) ... checked the charge (it was fine ... smile). This gun is a long term test project of my Tri-Valve Fabricated Butt Flask with over-fill regulator and quick fill.

You remember the wet molded and hand stitched leather covered butt flask with pistol grip quick fill.

I established that the gun liked the slugs with the peep sights, then decided ... what the heck ... I grabbed the scope off the Chaparral and clamped it on one of the accessory rails. As you can see ... the brass peep unit remains mounted. This long eye relief 4X just looks right around it. You see only the most vague smear which is easily ignored.

Here's two different slugs I've developed over the last few months. The gun likes them both. The bottom group is the latest 53.8 grain slug. The Nautilus has various power settings. I thought there were five. I forgot myself - when I took it down to reset it ... I realized there are seven. These slugs were shot with it set on the lowest setting. At that setting, it was smooth, quiet, and shot forever on air. You remember, I'm only running this Nautilus on a 2,000 psi fill. The slugs on this lowest setting were shot at about 650 fps.

What can you do with that?

Click, click ... verify aim, post a penny, fire, examine penny crater, find penny and slug eight yards back. Smacks pretty hard for being smooth, quiet, and getting a ton of shots.

Prior to changing the power, I'd chronoed this same slug on "yellow" at 905 fps. The power progression is green, blue, yellow, orange, red, blank, and blank. (Those are the two thermonuclear settings I'd forgotten about ... ;?) I don't know what top speed is ... sorry ... you'll have to suffer along with me til we find out.


It was back to work on a Delta 32 Magnum. Drilling and tapping.

This a pair of guns. Some of the parts in it's build tray on the furniture dollies. You note many other project boxes with their build sheets on the other dolly as well.

Onward and upward.

Thanks for reading.
