Still playing - have access to a roll crimping die (really need to buy my own) so I can put up some decent loads that will give some consistency.

Using AA Steel (and/or Longshot), I am quite sure of getting upwards of 1,800fps to 1,900fps with a .720" ball of around 550gr. weight in my Mossberg model 835 24" bl'd rifle. Blue dot should get upwards of 1,600fps.

Note that the round ball factory 7 dram (191gr.BP)12 bore load mentioned in WW Greener's book ran 1,584fps, ball weight given as 599gr.-perhaps a Very shot conical.- pg.689.

I have .662" (16 bore), .675"(<15 bore), 684"(<14 bore), .705" (<13 bore), .715"(>13 bore), .724"(<12 bore), .735"(>12 bore) and .740"(<11 bore) moulds.

My Mossy's groove depth is .724", so I'll use the .724" mold at around 550gr. in WW metal.
