When I play with different loads in my muzzle loaders I run them through my Caldwell chronograph.

Since I mostly do my test shot in my workshop, and I am too cheap to spring for a chronograph that comes equipped for night indoor use, I needed to figure out how to use it indoors. My solution is to hang two Harbor Freight LED Lights under the sun shade. upload_2020-5-17_12-39-44.jpeg

This lists at $3.98 in the Harbor Freight catalog, but there often are coupons available giving them away free with any purchase. To hang them from the sun shades I bent a piece of 5/8” steel banding material around the sun shade and used the magnet on the side of the light away from the light to hang it from.

Not the most elegant solution, but it works.
 
There are two kinds of people on this planet. Those who have shot their chronograph and those that have not yet shot their chronograph...
I’ve never shot mine but I hit my Chrony F1 with a wad which was seated beneath a .54 caliber round ball. Chrony used to warn about that in the manual. I sent it in and they fixed me right up for the cost of postage both ways, I thought that was pretty good of them.

These days if wads are involved in the load chain I mount a small piece of 1/4” plywood in n front of the unit... so far so good.

It has been a while, but if I remember correctly I was trying out very low loads and the .50 PRB barely cleared the barrel and I was shooting at about 25'. As I said, stuff happens.

I would hope that would be a one time event... My mishap occurred at least 20 years ago without a single repeat...
