All of the ballistic tables that I have seen list the numbers for the 7 1/2 inch barrel. How much of an increase would the 9 1/2 inch realize when comparing like loads? Thanks

I don`t have any experiance with this round but I`d venture about a 50fps gain for the extra 2"

Interesting that it isn't a bigger difference. 1350fps from a 71/2 and 1400 fps from a 9 1/2. The 7 1/2 seems easier to holster and wouldn't be too much of a handicap.

Ol' Joe..... been to any good Polka parties in Owosso lately?
