Which chronograph?

[harrygunner]

Thanks for that info.

I'm going out to play again soon.  Embarrassed to say, my hands were cold in 48 degree weather. Probably will take a few seasons for my bod to forget California weather. I'm going to buy some shooting gloves to block the wind.

I realized I needed to focus on a point far beyond the chronograph and forget it was there to avoid hitting any part of it. Good shooters have hit theirs, so I like the idea about using wooden or bamboo rods.

I use wood dowels, covered with colored drinking straws (usually blue close, red far).  I have fabric (bandage) tape on the straws to indicate the sweet spot, which is 5-9" on mine.  I always shoot from a stationary rest (shooting bench), with a target at 50' behind it.  I set up the bench and target, then position the chronograph accordingly, mounted to a heavy duty articulating camera tripod.  I try to do most of my 'graphing on a cloudy day.  No screens needed, and no errors.  In the summer, I shoot from under a canopy with a silver fabric.  I get 1 or 2 errors in 100 shots with that, but better than 2-4 with the screens.  Then, I only use a dowel/straw for positioning.  At some time in the future (spring, probably), I'll fab an all steel chrono station to fully house it, with only slots for the sensors.  I also use a specific .22LR rifle and Stingers to calibrate.  This combination only varies ~20 FPS, from a 20* winter day, to 110* in the summer.  Very consistent, and I have enough rounds of the same lot for years and years of calibrations (I use them only for this).  The rifle is a Browning Take-Down clone (POS), and it's the most accurate .22LR I've ever had.  I use it to pick off squirrels at will, at 100+ yds with iron sights.

Here are some pictures of mine at post #9 where I use an re-purposed ironing board for CHRONY setup...Folds flat, adjustible hight, can place weight on legs for windy conditions but most of all it is FREEBIE!

Can be adjusted to an angle if needed by placing blocks/bricks for elevation of one end or the other.  Protection for the unit can be simple piece of steel plate on the slope as shown or heavy plate to take the direct hit.

Wow, missed that thread under 'Range reports'. (I should have posted my readings under that section.)

The ironing board with the steel plate protector is cool. Might I suggest a camo motif for the ironing board? 

I'm going to get some wooden rods to hold the screens. Based on a video I saw, seems like they would make things less painful if hit. Thanks for the ideas.

I am a big fan of the CED chronograph.

Pay attention to how The_Shadow has armored his.  You WILL eventually shoot one.

My rebuild has been working out excellent!
