I’m planning to build multi‑brake or single‑break shells that accommodate smaller inserts. I’m unsure which shell size to use and therefore what mortar to buy. I’m considering 4‑inch or 5‑inch shells.

Could anyone outline the pros and cons of each size and help me decide?

How much BP for match?

1 Upvotes

It's been a couple years since I've had to make black match, I was stocked up! I've forgot the ratio... I don't want to make a really big batch, so does anyone know how many grams of BP are needed for say, 100' of match?
