HW/Weihrauch Surprisingly Disappointing & Confused

[KRich]

For Christmas I finally broke down and bought a Competition Electronics ProChrono DLX. I wanted to see exactly where my 3 Weihrauch's stood. performance wise.
The oldest of the bunch, the HW95 (with a new Vortek PG4 Tune kit) perfomed as expected with an average 765fps shooting H&N Baracuda Match 10.65g pellets.
The HW90, after pumping a tad more air into it, is shooting 905fps average using the same pellets.

This is where Im totally confused and a bit peeved. My HW80 with very little pellets ran throught it (probably less than 250), is averaging a mere 425fps using the same 10.65g H&N's. This rifle is supposed to be a "Magnum" springer or so I thought, yet my Benji & Sheridan's blow it out of the water as far as power goes.

Any idea why Im getting such lackluster performance out of this HW80? Its NEVER been stored cocked, thats for sure. Do I need to break down and buy a Vortek kit for this one as well ? The Vortek kits are smooth as silk and I love how it tamed the HW95, but I read somewhere that power may suffer if I treid putting the kit in the HW80. It seems at this point I have nothing to loose. Geeze.

There is nothiing wrong with the App. The problem is me. The App however WILL NOT allow entry of bullet grains to the 2nd decimal point. Looking over my data entry, I found that I did not enter ANY decimal places for bullet grain weight. After adjusting the data for the above example Field Target Trophy, if I add .6 then the FPE changers (of course) to better reflect actual numbers. MY BAD for not realizing this. It would be great to have bullet gr weight entered to the hundredths obviously......I was just on the phone with Competition Electronics who make he Chrony, And begged them to update the app to allow grain weight to be entered to the 2nd decimal point, and they told me it couldnt be done....according to the app development team. I explained how important that is to our sport, as our projectiles are rather small compaired to our firearms counterpart. It probably fell on def ears.

Thank you for taking the time to clarify that for me. I'd be ok with tenths of grains. It'll be really close without the hundredths place. You could always round the hundredth place up or down if you wanted.

I have an earlier ProChrono and it's been great for years. It's got hundreds of hours on it. It occasionally gets wonky now in bright angled light so I use my indoor lighting kit. That usually fixes it. I use my chronograph ALOT so I wanted to treat myself to a second unit that recorded the strings and did the math for me. If it didn't do the math right it'd kinda defeat much of my reason to get a new one.

Having a second unit also allows you to calculate accurate Ballistic Coefficients. Advertised or posted BCs can be wildly wrong. A pellets BC can vary with speed and even individual barrel as well.

Thanks again for explaining what happened. I hope you are thoroughly enjoying your Hw80

Yeah, I hate that you can't input the hundredth weight, I just round up or down. 14.66 I input 14.7 18.13 is 18.1 it seam to be close enough.

Glad I could get that clarified Ron. I felt like a horses a*^ when I realized what I had done. Anyway, this Chrony seems to do a real fine job, and having the app call out each shot's FPS is pretty awesome. Have a great day sir...
