    Modifying F1 Master Chrony

    I forgot to point out, I used a low powered pellet gun on the potting soil. Don't try anything any bigger. I just got the thought that I didn't want some one thinking it was safe to use potting soil as a backup. I had 2 bags, one behind the other and only for a low powered pellet gun!!

    Modifying F1 Master Chrony

    The led lights are from Chrony. As I mentioned in the article, I'm not sure if automotive light strips will work. The strings you can buy at automotive stores are longer and I would think that might increase the Chrony's field of view. Anyway, this is kind of a work in progress. My unit works...

    Modifying F1 Master Chrony

    Part II Screen Backside by Bulletstarter posted Apr 15, 2017 at 11:05 AM This is the backside of the unit. There are some velcro strips on there because I tried using attached cardboard to shield the screens but it didn't work. That's when I decided to turn it upside down. You will notice...

    Modifying F1 Master Chrony

    Had my annual root canal (aka income tax appointment) yesterday afternoon and got my taxes done. This morning I finished taking pictures and now am ready to start the narrative. I've written all kinds of computer programs but have not tried to put a presentation on this site. So bear with...

    Modifying F1 Master Chrony

    I had a senior moment when I titled this thread by saying I have an F1 Chrony. I had an F1 Chrony and several years ago I got caught in a violent downpour, grabbed my rifles and forgot my Chrony. Several hours later I waded down to the Chrony which was underwater and retrieved it. The Chrony was...

    Modifying F1 Master Chrony

    It may be a few days to get the pics because I'm in the middle of my annual root canal, aka income tax appointment. I appreciate the comments and will take detailed photos and put together detailed instructions. I was a teacher for 29 years so bear with me if I over-explain. Thanks for the...

    Modifying F1 Master Chrony

    I have been shooting and reloading since the 60's. I started with and still have an Oehler 33 with unshot screens that still works. However I bought an F1 MASTER Chrony for convenience. I was disappointed in the unreliability of it and bought the lighted shades. They worked fine on cloudy days...

    20 practical reloading

    wildcats In 1967 I inherited a 30 carbine and about 1200 rounds of military brass. I decided to build a 22-30, a 30 carbine necked down to 22 caliber. I didn't have a chronograph then but I thought I had a pretty hot caliber. I put a 4X Weaver scope on it and thought I had a great rig. The...

    20 practical reloading

    info about 20 practical I knew very little about the 20 practical 18 months ago. I used a 204 Ruger and .223 Nato for years as my main prairie dog guns. As the price of ingredients and brass continued to go up, I started to search for a cheaper alternative for the 204. Just for the heck of it I...
