RwsMike, don’t know if you wanted chrono numbers on my .177 or his .22, but this is what I got yesterday. Chrono on 35E says avg of 829 FPS, spread of 6, std dev of 2, just under 13 FPE. 10 shot string with AA Diablo Field 8.4.

HW35E .177

This is great info. Thanks cjtamu! I'm unable to chrono my .22 right now as I need a lighting solution for indoors.
Question: My 35 E is new and only has about 50 rounds through it. Would we expect velocity fpe to go up as it is used more or decrease ?
thanks

Velocity will frequently drop a bit in the short term, as the (often excessive) factory lubes burn off! But over time it should increase a little as the parts settle in. The concept of break-in time is often forgotten in our instant/electronic age, but is very much applicable to a simple mechanical device like a spring-piston airgun.

I chrono’d my new HW 35 E in .22. It’s currently doing 550fps to 560 fps. I hope it improves as that just under 10 fpe. I think I’ll be installing a vortek hogh output kit asap. If anyone has any recommendations please let me know. It’s easy and pleasant to cock but I think a bit more power needed.

That seems low. My .177 is. making almost 13. Kim’s .22 HW50 makes 12 and my 95 makes 16-17 depending on pellets. What are you using? Both our guns shoot JSB well. 13.43 in the 50 and 15.89 in the 95. H&N FTT also shoot well in both.

My hw 50s in .177 shows only about 9fpe. 8.44 jsb at 705 fps. Could my caldwell chrono be in error?
I’m using crosman 14.35 dome premier in the hw 35 e

I’m not sure what that gun should make in .177. You mentioned needing an indoor light source for your chrono. Did you get that solved or did you chrono outside? If inside it’s possible there were problems with lighting.

I purchased some LED lighting for my chrono. I tried my .20 cal HW90 and it’s showing 850 fps+ or 22 fpe + which seems correct. I think the new 35 E is only rated about 575 fps in .22. I think my cheono is accurate enough which means I’m going to purchase some vortek. HO kits in the near future

I have a HW35E in .22, I live and shoot at 4700ft elevation. My gun shoots at 550 with H&N FTT with Anschutz diopter, Motorhead did the tune on my 35, the performance is what I expected, buttery smooth and fun to shoot with diopter.

HWs typically have pretty oversized bores, and Crosmans tend to be pretty small, with hard skirts.
Try an equal weight pellet of softer lead like a JSB and see how it does. Might help.
But likely it will only be decently accurate with a large pellet like a Field Target Trophy in 5.53 and up.
Either way, a whole lot of song and dance to gain 1fpe that won't be very noticeable in practical use. Take it for what it is and enjoy shooting it when you find an accurate pellet.

Thanks for the data and feedback gents. I love the rifle and shooting it. With 560 fps give or take with the 14.3 that’s fine for me. I bought it for it’s beauty and a fun short range plunking. Ill try a vortek kit and maybe one of their vac piston seals in the future. Just for learning and fun really. I have an hw 90 and Hw 80 for bigger power. The great thing about air rifles is that it’s an excuse to buy more for each purpose

Glad you’re happy with it. I really like mine. One thing I always forget to mention when talking chrono numbers is I’m only 36’ above seal level. So, YMMV depending on elevation.

My factory .177 HW50 started at just over 11 fpe but several tins later has settled into mid to high 10 fpe.

Thank you for the info....looks like 177 cal might be the sweet spot for velocity in a hw 35

I had a .22 caliber HW50 and sold it. At my elevation of 2900 feet, the gun just didn't work well. I ordered the .177 HW35E and it is much nicer to shoot. .177 is the sweet spot for the 35 or 50 in my humble opinion.

I have an HW50S in .177 and HW35E in .22. I think I need a HW35E in .177 to compare 
I'm on a quest to have as many as possible as they're the best made rifles out there (for me anyways). The 35 E is so much fun to shoot with my peep site on it. I tried the rws hollow point last night and there's more velocity with good accuracy there. so much fun!
