I'm imagining setting up paintballs on golf tees at 50 yards and just launching JSB Kings with a hope and a prayer.

HW30S .25?
- Thread starter Sqwirl57
- Start date
I'm not sure if a Hw30 could lob a 25 caliber 25.89 grain pellet 50 yards. I'm not sure you'll see 400 fps either. It'll be like a red Ryder in the 3 something fps range.
177cal Hw30 =700 fps
22 cal Hw30 = <500 fps
25 cal Hw30 =???
I get what you're doing. More power to you. I shoot beer cans at a hundred yards with my 177 Hw30s all the time. Takes forever to get down there and lands with a whopping two fpe. Still makes me giggle every time.
Have fun with it

Totally for it! People tried to steer me away from the 30 in 22 cal. I didn't listen. It's the gun I have the most fun with so far. It's puts the wallop on tin cans. That's my main activity with it. I rested on my knee and shot a tiny little group at 15 yards all touching with iron sights so it has the precision if needed. Give the.25 a go. Give the 22 the go. It think you'll LOVE it!

Not something I'd ever consider - but understand your limited use.
Wondering if the HW30S platform is functional in .25 - you may break springs frequently from the load.
Sounds like your bored and looking for something to do .......
However, I just did something I thought I'd never do .... got a HW80SLK in .177 caliber. Exactly the opposite of what you're suggesting

Bored and looking for something to do is an accurate statement lol. I swore I'd never get an 80 in .177 too just because the .22 seemed much more appropriate. Now I've had the 80 in my cart for a few weeks because I think I'd really like it in .177... its a tough call.Not something I'd ever consider - but understand your limited use.

I imagine it'll be a tuning project just as much as its a mechanical project. A slightly heftier spring will almost certainly be a must. When I tuned my 430L I ended up swapping in my spare D56 full power spring and losing a couple of coils to get it down to 11ftlbs for FT. It ended up working great.Not something I'd ever consider - but understand your limited use.

I think it would work great for what you’re talking about. I have a HW30S in .22 tuned by John in Pa.
He installed a Airgun Headquarters indoor shooting kit, so it’s shooting slower than the stock rifle. It’s so very easy to cock and it’s really accurate. Very loopy trajectory past 15 yards, but still very accurate.
I wanted a little indoor springer that would be easy for me to use as I get older.
I bet the .25 would act similarly to my tuned down .22 and it would be devastating to a rodent lol!
Definitely post about it when you get done!

Vortek sold a Hw30SHO kit that was supposed to make 10 fpe in 22. It came with a 0.118 spring instead of the normal 0.113". I installed it and it made a little over 8 fpe which was same as the standard kit in a the 177 I was tuning alongside of it. I called Tom at Vortek. He sent me a longer 0.118 spring. It made maybe a half pound more energy. Still under 9 fpe. The gun was tough to cock and felt as if I was pushing the linkage past the design limits. This made the rifle unenjoyable to shoot and probably not long for the world.
I called Tom again and he couldn't understand why I wasn't getting the ten fpe he was. I told him there was no way I could get there with every trick I knew. He said he tested it in three 22 Hw30s and only an old one produced ten and two were the same as my results. He blamed it on the newer 22 barrels and discontinued the kit.
Bottom line the Hw30 can only make so much energy by stiffening up a spring. Most of mine run between 8 and 8.5 fpe regardless of caliber. I've tried stiffer and longer springs but the energy stalls and all you wind up with is a small gun that's hard to cock that makes the same energy. My tunes start between 8.2 & 8.5 fpe depending on the individual guns sealing capabilities. They usual soften to about 8 fpe in a few thousand shots.
I'm pretty familiar with these guns. Unless Tom is right about the 22 barrels and the 25 caliber barrels are better, I don't think you'll see 400 fps or much over 8 fpe in 25 regardless of spring. The good news is the larger caliber with standard weight 25 caliber pellets will have a lower start pressure and shouldn't break anymore springs than any other Hw30. IMO Weihrauch springs don't last long anyway so you'll be replacing it soon enough if you shoot it regularly.
Have fun with it. I look forward to seeing you build it. It'll be a real mortar but I pity the mouse or chipper it lands on.

"Am I crazy or...."
Yes. So says The Manic Compressive. But WHO ISN'T (in 2022)?
FWIW, one of my (saner) best buddies used to shoot field target competition with a .25 BSA springer producing about 500 FPS... AND LOVED IT! Said it was a real kick for him (and spectators) to see that mortar round fly out there, swish through the kill-zone of long range (55 yard) field targets, and SLAM them down! In other words, amplifying the sensual-feedback experience that is field target.
Hot-rodders have a saying, "There's no substitute for cubic inches".
Embrace your insanity! Matters not if no-one else does.

Hmmmmmm.....
Maybe I should take peoples advice and switch this project from the 30S to the 50S. A FT capable sub 12 .25 could be fun too and I always have the option of tuning it even lower.
Alright I some some serious pondering to do now.

Fwiw. 13 fpe with a 26 gr pellet is about 475 fps. 13 fpe is a reasonable expectation for a Hw50. It's also about the same velocity as a 22 caliber Hw30. It's pretty slow.

Ok so after some thought, I'm fairly certain you are right. A 30S would be fun but the 50S is just a much better platform and nearly as dumb as the 30S anyway so... close enough?
I think my big selling point is moving from a ball to wedge lockup. The 50 will allow for a heavier barrel which should help tame what I assume is going to be an incredibly hold sensative gun.
Upvote 0
Why is the gun to be hold sensitive? Why would the barrel be heavier? What route are you taking to increase the caliber to 25?
Upvote 0
Its going to be a very slow pellet moving down a ~15" barrel. I'm not positive on how hold sensative it will actually be but I imagine its going to be up there.
As far as "how" is concerned, I'm still working that out. From what I'm reading the barrel is pressed with a welded pin locking it in. The way I see it I have two options. I can locate that pin, drill the welds, punch the pin, and press out the barrel.
The second option would be to just drill the old barrel out, toss the new barrel in the lathe and resize it to fit the block, drill and install a new pin. After that it would be a matter of facing the barrel to accept a breech seal.
I am still in the research phase of this though and I'm not 100% sure how the factory barrel is actually installed into the gun. Between work and whatnot I've only got an hour or two into looking into it. If anyone has any suggestions here I'm all ears though.
The factory barrel is 15mm but I do have the option of going 16mm or 17mm as well. The breach block itself is 17mm wide so any of these options could work well and a heavier bull barrel look may work well. I have an ARH muzzle weight on hand already so the 16mm may not be a bad choice.

About a year ago I ordered a HW30 .22. They sent me a .177. by mistake.
They were going to send me a .22 barrel. I agreed, then I noticed on the breech block it had 495 fps on it. I opted for the proper gun.
My point if they were going to send me a barrel you can change it.
I did see on y-tube a guy removed a barrel with heat. Crow

What if, instead of rebarreling the rifle, you installed a .25 cal. Barrel liner. They're available through FX for various rifles. Basically you drill out the bore to the proper diameter to receive the liner and epoxy the liner in place. The breech seal should remain intact and the machining work would be reduced to a minimum.
