What size paper tube for 37mm?
I'm trying to find the correnct size cardboard tube and end cap pieces to use in 37mm. Does anyone know off hand?
Thanks in advance,
Depends on what case your using, most projectiles have a high degree of tolerance and don't really contact the tube walls due t not being rifled. The most important aspect is the fit to the casing.
MLR offers cardboard tubes for $1 ea that are designed to fit their reusable casings. I just ordered some' i'll let you know how it works out.
Thanks for the reply.
I have some ASA alluminum hulls on the way and want to get the paper tubes to cut to size. I'm not a full moron and convert the 37mm to standard sizes but can't exactly figure out what size the components run with when ordering. My next option is to calliper the hulls that show up and go from there.

My ASA doesn't fit a 209 primer snuggly, you have to use paper to take up the tolerance, which is crap IMO, they could take the time to machine these things to spec. My MLR shells are still in the mail I hope they fit the primers correctly.
BT 56 tube works for me. Mainly, though I like to take the easy way out. 5 hour energy drink bottles fit most of my cases like a dream, and are reliable and easy to load. I used to use 35mm film canisters, but they don't fit too well. Find a few friends with the 5 hour addiction, and you're set!
