Finally got a .25 springer.
« on: July 08, 2018, 11:37:46 PM »
About a year and a half ago I picked up a Remington Express in .22 for 80$ at Wally World. Nice rifle, especially for the price.

Eventually I ended up with 5 airguns in .22 and I didnít shoot the Express to much.

I shot it over the clock @ 18fpe. I thought ďIíve been curious about .25 for a while, and the Express would pretty much make a 2/3 scale Hatsan 135 in .30.Ē

So I ordered a .25 xs28 barrel from Flying Dragon. The breach block is NOT plug and play. The hole that connects the cocking lever to the breach block is a lot further forward on the XS28. So I matched up the breach blocks and transferred the hole through with a pencil lead and center punch.

The groove for the cocking slot in the breach block needed to be moved back.

At work I have access to a mill, lathe and drill press... but kept forgetting to bring the piece in.

I finally got sick of looking at the .25 barrel and figured what the heck. Started cutting barrel with tube cutter until I could juuuussst feel extra resistance pushing a pellet through. Completed cut by clamping barrel to a 2x6 and cutting with an angle grinder. Dressed outside of cut with flap disc. Drilled cocking lever hole with hand held corded drill. Chased cocking lever groove with cut disc. Cleaned up edge groove corners with die grinder ďflap sandĒ bit. Cleaned everything with electromotive and painted with black finger nail polish.

Put gun back together. Function test good, havenít gone for accuracy or fpe yet. Havenít crowned barrel yet.

Just happy I got a .25 without buying another gun to take up space.

Maybe I could have used the Octane/D350/Air Magnum cocking lever, but those are all one piece and I didnít want to mess with the stock, in case I want to go back to .22 or .177...

Do you guys think 18fpe is 18fpe? That should put it around 550fps, but MMellick said he thinks it will be lucky to get 400fps.

What do you guys think?

You can see the previous cocking link holes and how much longer the breach block is.

There was a post before where I agreed that for most people (maybe me also?) a 500fps .25 with a low mag scope or red dot was just the ticket for pesting things like rabbits out the back door of a house to like 15 yards or so.

We'll see if I like it. If not, I have 2 .22 B25 barrels to go back to.

My guess would be about 450fps... w/ 25.4 grn

Maybe. Do you think it would go down to 11.5fpe from me cutting the barrel or just not enough horspower in the powerplant for the bigger pellet?

Your gun would have likely still put out 18 foot pounds with a 20ish grain pellet, but will not do so with such a short barrel.

We'll see.

I just measured it. 8.8"

I was thinking shortening the length wouldn't decrease the FPE because the volume is still pretty healthy at .43ci. But you guys might be right as the loud report may tell me I'm losing more air that is still expanding than I counted on.

If it is even close to original FPE, I'll be stoked.

This is the gun I was going to ask Rocker1 to make an LDC with front cap removable for.

Being so short how is it to cock?  I would have probably went with a 12"-14" barrel and mod but looks good as is.

Astronomically difficult.

I hope to put a can on the end to stretch it out a little bit, mute the report, and give my hand a better grip.

I thought of this as kind of a novelty gun from the start, not an easy plinker, but something not everyone has, that I kind of created myself.

Both actually, springers generally tend to lose fpe when going above .22 cal. & Also from going that short on the barrel. I am basing that assumption on my own experience with a storm xt that I chopped down to 9Ē barrel which took it from around 15fpe to 11fpe and it was in .177 cal.

OK! Pretty stoked.

Here we go. FTT 20gr.

598
594
595
604
594
597

So that's 15.8fpe. Felt some pretty good piston slap, so I wouldn't be surprised to get maybe half of my 18fpe back with a heavier pellet.

To boot it was pretty accurate at 15ish yards. Pellet on pellet, but the scope was not wanting to adjust well... I didn't threadlock the breach block through bolt or the stock screws, as I wasn't sure how it would work out. Also, not crowned yet for the same reason.

So, I'm really pleased with this. In the shortish term I will crown it and put a pickle on the barrel. I'm also interested in maybe putting a shotgun bead tapped right into the LDC, with iron sights in the back.

Then asking Motorhead to tune it.

Thank you all for reading.

So.

25.4 gr. JSBs did eliminate piston slap.

They did not raise FPE. It is almost exactly the same. Rifle is quieter.

Rested on kids piano bench, pulled into shoulder like a center fire rifle. Pretty much hole in hole at 11 yards. Changed scope to 30mm red dot. Zeroed at 8.5 yards should give me a PBZ to 30 yards. We'll see.

Next time, I will leave on another inch of barrel. Still pleased with results.

The shortie springer post put it in my mind to finish this post.

Tore gun down. Cleaned out all petro lube. Lubed with Krytox 217 and found piston does not slam with 31gr. Barracudas.

FPE now at 16.75.
