I have two Thompson Center round ball molds that I would like to identify, as TC puts a stock number on the mold not a ball size. To complicate things, the numbers on the original box don't even match the number that's on the.ball mold. If I recall correctly, the old Thompson Center catalogs have the needed information under the ball mold description in their catalogs. I would be very grateful if someone had some old catalogs lying around that could be put to use to investigating this mystery.

I am looking for a mold that has the number 224 and 626. I believe the 224 maybe a 550 ball. Thank you!

cast a couple and put a caliper on them

My old T/C catalogs only list the T/C numbers. These are all 4 digit numbers.
I have 36cal, 45 cal, and 50 cal moulds in the garage. When I get a chance, I will check them for you.

Sort of off topic but I was on the phone with the fellow that runs their fill orders department yesterday, (At headquarters). I lost my ram rod for my T/C Impact muzzle loader and couldn't find one on line anywhere.
He told me they had been sold out since early summer and didn't know when they would be making more, and not just for that model, but most models. He had expected a large run several months ago but now had no clue. And he hinted that ram rods weren't the only thing they were behind on.

Thanks for the responses! Much appreciated!
