Title: Finnally bought a chrono
Post by: tommac919 on August 01 2016 11:05:35 AM MDT
Well, I finally bought a chronograph.... but not the way I wanted and now I need another

A friend had his set up and I had a couple of rounds to test so of course I asked to fire 5 rounds.

Stock G20.3, 200 gr xtp with new starline brass / remington 2.5 primer/1.258 oal  and a good dose of 800x ( but less than Underwood ).
( had already fired a few lower sets with no problems )

first shot 1194fps
second shot chrono ! DAMMN IT !! " curses inserted here  "

Well At least I got one.... Friend looks over and says looks like you bought a chrono... I pulled out $150 and he said fine.

So, I'm looking for a new chrono ( I let him carry the pieces home )

I will say the loads with the 200xtp and 800x are accurate, before the above I was in the 4" ring at 25ft with 10 shots. I was looking to hit 1200fps and fiq I got that. All cases looked normal with the glock bulge ( no smiles ) and the primer starting to flatten on the last set of loads... cases measured in at mostly at  .433 some at .4335 and out of 20, two were .434.

Chrony's can be rebuilt as the sell the parts at reasonable prices but their shipping outrageous!
The electronics are down low inside the plastic housings and sometimes they are OK and the housings and clear sensor window is all that is needed to replace.

It really wasn't that bad and was fixable..... Just using poetic license.

He bought lunch and a bottle of jack- honey , ...so it wasn't a bad day after all. We went and cleaned some brass (loaded the hopper) and laughed it off ( at my expense )
