I was thinking the same on the 25 or 26mm seal when you described your fit issues. Mycapt65 gives sound advice. Looking forward to a report as the proper parts break in.

Tuning Hw30 Vortek PG4 + Short Stroke Piston seal
- Thread starter RicL
- Start date
If it's a pre safety it has a longer cylinder and you need to add spacing. About .300 or .350. You could measure and see where it coil binds. If you want full power.

Interesting. I never knew that about the pre safety guns. I stand corrected about the springs. Although missing 0.350 preload wouldn't account for all the missing velocity in this particular rifle.
Obviously you're more familiar with the pre-saftey Beemans than I am. Were any of them leather piston sealed? I was under the impression all the Beeman Weihrauch imports were synthetic sealed guns.

Earlier HW30 had leather. Not R7's. JM added a spacer to the kits for pre safety and Paul Watts recommends it as well (.350 or more.).
The one with the .040 oversize seal ? How did the nice man get that in there? A learning experience for sure. Experience is the teacher!

So far, I've been enjoying shooting my bone stock(except for the Corcoran stock) Beeman R7 just as it is.

I've shot my Hw30s out to hundred several times. No groups, just plinking beer cans. On a calm day I could cut the can in half. A stock R7 should push an 8.44 low six hundreds. Faster than most 25 caliber spring guns.

The short stroke seal arrives on Tuesday, I'll put it in, test it out and report back on the shot cycle. Don't have a Chrono yet, but hoping to pick up the new FX V2 chronograph when it arrives to the states.

My range is 55 yards. When the wind cooperates it is very easy to hit dime sized targets. The HW30 is an amazing rifle.

Thanks. It's friggin hysterical too. Takes so long for the pellet to get there and then there's a noticeable sound delay between the seeing impact movement and hearing the tink sound of two whopping pounds of energy.
At Sean Gabrells range I went fifteen in a row on a 4" square junction block cover at 102 yards. Great guns, by far my favorites.

Installed the JM kit plus the short stroke piston seal. Getting 447 fps average w/ 13.73 jsb .20s. The shot cycle is super nice though. Also had the vortek in and that was much snappie and the velocity felt higher, I’ll have to chrono that some other time.

Sorry, have since sold that particular 30. Worth it for experimenting and just how fun it was to shoot. Keep in mind I was limited to ~10 yards. Either kit works, kinda felt like a shooting a pcp, (uninterrupted view through the scope while firing).
