Hi all,
After discovering that the new hard black plastic Smith tubes only last about 5-6 shots before splitting, I have investigated brass tubes.
Initially I bought 5 of them from Lodgewood. These have a grooved tail. The case mouth is about .514" in diameter. The powder chamber is about .390" in diameter. Then I picked up 100 cases from a shooter here on the forum that have a knurled tail. They are much better in that they have about a .518" case mouth, and the powder chamber is about .431" which allows it to hold 32 grains of powder 3F Goex, which is what I have found to work best (for 3F Goex, which is all I have tried).
For Pietta Smiths, I've been sizing to .515, whereas my original seems to like a bigger bullet (my teammate is shooting the Eras Gone Smith as-cast - about .518" in diameter).
Does anyone know who made the knurled version? I like the larger case mouth and powder chamber.
