Vortex PG3 HO

[Duckfish]

Just installed one in my TX200. WOW is all I can say! I replaced a PG2 12 lb kit which was working fine. Now it shoots like a tuned gun that would have cost much much more plus would have taken lord knows how long plus the exposure of shipping damage.

Super accurate with JSB 8.4 within the first 20 shots. Ran it over the chrony JSB 10.3 at 845 fps. How the heck can you do better? Easy Peasy!

Wow ! What kind of velocity do you get with the 8.44 gr ?

 

[Duckfish]

Haven't had time to do that yet. Im guessing at least 850 -875. I expect that to fall off some as the kit wears in. 



Actually, I will be more inpressed with down range accuracy. I'm looking forward to shooting some 55 yd groups on range day, (Wednesday ) weather permitting.

Stay tuned

For what it's worth if you run through the numbers the PG3 appears to be more efficient than the PG2. Tom says this is due to the open coil design. All I know is the first PG3 kit I received was making almost the same velocity as my old PG2, but with noticeably less cocking force. Tom had to clip a couple coils to get the velocity where I wanted it, which reduced cocking force even further. Mine is still going strong and no complaints after a couple tins through the gun.

Probably in the 920-940fps with 8.44s. Yo!

If your running 845 with a 10.3 I would agree with Yo. My RWS 34 with the JSB 8.44gr (4.53mm head) has settled into the 925-930 fps range. And yes, if you just tuned it it's probably still burning a little lube with each shot. I would expect those 10.3 gr to drop to the 820-830 fps range once excessive lube is burned off.

 

[Duckfish]

Nope no tune. Just pulled out the 12 lb kit and slipped in the HO kit in its place.

Range day! Hooray! Here are a couple 50-55yd groups. Range has markers and I put it at what they marked at 55. My scope ranged it at 50. Either way normal Concord winds.

Very impressed with the HO kit.

 

[Michigander]

Good shooting! Happy with my PG3 as well. Had a zero wind day so checked zero and shot some groups. Gun is holding zero very well, not hold sensitive. Just have to adjust a couple clicks one way or the other depending on which way the wind is blowing.

Following up with chrony data to go along with targets above. 16ftlb with stdev 3.7, ain't too shabby IMO.

I’ll get around to showing what my John Thomas PG2’s with buttoned pistons can do.

I’m seriously thinking about getting several redone with PG3’s and tighten any tolerances that have worn.

Great shooting.

The PG3 does look to be a better performer than the PG2. The OEM setup for my TX200HC gave 16.3 ft-lb energy with 8.44s, while the most I ever got from the PG2-HO was 15.0 ft-lb with any pellet I tried. Although I never tried adding spacers. 

 

[JamesD.]

Factory TX200’s should be around 16 but I believe PG3 has tighter tolerances.

I’ve seen PG2’s do 25ftlbs in .22 w/18.13 from a RWS 54.

Great shooting !
