Oh, I'm sure it'll do what I need it to. But getting an extra 50+ fps with same accuracy never hurt anybody.
Can anybody shed some light on their experience? Thanks!

Will be picking up a HW30s in .177 soon for some short distance pesting. Looking at doing a Vortek kit on it to bump the power a little bit. But, also saw mention of a o-ring tune done by Ed Canoles where guys were gettting in the mid 600's w/ 8+ grain pellets.Quote from: txaggie929 on February 22, 2018, 02:47:23 PMOh, I'm sure it'll do what I need it to.

Using the same spring kit I found that the velocity gain using an oring seal was insignificant at around 10fps. LOL....even variations in the atmosphere and temp cam alter velocity that much. The old design HW95 parachute seal with the thin sealing edge created a lot of drag when pressurized and I used to get about 60fps increase using a custom fitted oring sealed piston cap, however that doesn't happen with the new HW95 seals unless the gun is dieseling..........For me, the advantage of the custom aluminum oring sealed piston cap is the fact that with a .070 nominal cross section oring there is very little "rubber and lube" being compressed against the receiver ID so changes in temperature (like a 25 degree F shift during an early spring shooting session) which affect the durometer of the "rubber" or viscosity of the lube don't have as much effect on the poi. The thing that started my oring sealed piston cap experiment decades ago was an early spring field target match outside Harrisonburg, Virginia where the sight in was done during snow flurries but before the match ended the temps were in the upper 50s. Both my brother and I were shooting .177 R9s and during the match we both started missing more targets than usual. Shooting a a couple 20 yard tree trunks we found that we both had a 1" poi shift at only 20 yards. Funny thing was that the shift of my R9 was in the opposite direction of my brother's R9. Anywhoo......personally, if the temperature during a shooting session doesn't change very much it really doesn't matter what type of piston seal you use. After "oring sealing" my brother and I found another rather important benefit of oring sealing for squirrel hunting with out R9s. With the oring seal it only took a couple shots when we got to the "squirrel woods" to stabilize the poi unlike "the several" it took using the old style HW parachute seal and the poi during the hunt didn't change as much with the oring. I've read that the oring sealed piston is snappier than a factory HW piston seal, however with my R9 & HW95 I could detect no difference between the newer factory seal and the oring seal when shooting with similar velocity. LOL.....the newer HW seals don't "put the brake" on the piston like the older thin edged design would. Regardless, perhaps there are some that have upped the velocity of a R7 (HW30) by 50 fps with an oring seal but that hasn't happened with my HW95 vs the new design seal. Decades ago I bought a couple Chinese B3s for $19.95 each and cobbled together a single gun with the parts that actually shot pretty good, and the velocity using an oring sealed piston cap went from 550fps with the factory leather seal and 8.4 grain JSB Exacts to 700fps (150fps increase) with the same pellet. Here are a couple is a 5 shot groups I shot with the cobbled together B3............Factory B3 piston...After some truing up of the piston face and installing the oring sealed cap.........With factory irons at 25 yards.........After stripping off the "irons" and mounting a 6x Burris Compact scope.......... Currently I personally don't think there is much value in and oring sealed piston cap vs the newer design HW piston seal, especially if the shooting session temps don't vary very much.
Instead of pushing the HW30S to it's max and maybe harshening it a bit, I'd just get a HW50S.
