Dang it if it wasn't the brand new infrared chronograph!

I feel your pain brother!
Did the same thing to mine a couple of years ago.

Was yours homemade or store bought?

Mine was store bought top of the line .45-70 blue and yellow BB

Mine was a handloaded store bought 320 gr Performance Cast (NOT Cast Performance).

Crimp-on or plain gas check?

Can you tell if the gas check was crimped-on i.e. Hornady or a plain Lyman cas check?

The Lyman simply slip on and are easy to remove from the bullet; the Hornady usually crimp on very well and are difficult to remove.

Once the bullet exits the bore the gas check's work is done and it does not really matter if it fall off - unless you are shooting over a chronograph

I bought $50 worth of "insurance" for my $100 Chronograph in the form of two pieces of channel iron (one goes in front of and one sits on top of my Chrony) heavy enough to deflect a .500 S&W (I tried one).

Now, I just have to make sure I don't hit the diffuser supports.

Nice pictures. Thanks for sharing.

Hard cast woes

If it was Buffalo Bore it was probably Hornady gcs. The only time I had gc problems was the first few times I used a real hard cast bullet using a Lyman lubri-sizer. You actually need a gas check seater to make them work well, with Ly man checks.
