Where to find 10 gauge hulls

[OH Osthaus]

i do not remember seeing any reference to the brass in the spreadsheet

are you thinking base - the internal base wad?

There is a difference with the 12 but not as much as one would think IF the data for tapered walled hulls is also used for straight walled hulls. Looking at my IMR reloading manual, 1oz with a Win 209 primer and 15.5 in a Fed hull will make 5700psi at 1100fps. In the Win hull using 16grs makes 5000psi at 1100fps. Now that's not to say every powder and charge will react the same way, but there usually isn't a big difference, and at the low pressures we reload at I don't feel there's a lot to worry about. As we say over at the club - in a 12ga, 15 grains of anything is safe. JMHO

The chart states "winlb" as the hull... maybe I'm misinterpreting it?

[Paul Harm]

Maybe it should have been winbl, meaning win black hulls ? Just a guess.
