Re: big bore barrel source????

CowboyCS: Thanks for the info. I was just curious about the point blank range since I had thought of trying one of these really big bores on an elk next fall.

500Boswell: thanks for sending the pictures they'll be a big help.

Does anyone have any recommendations on the shape and number of grooves? I was thinking of using what seems to be considered standard forsyth rifling with 8 shallow grooves. It seems to be the common idea that they should be about 5 times the widths of the lands. Should the grooves be square which seems to be normal for Forsyth rifleing or rounded or flat bottomed with round corners or something else? I like round grooves like are in the barrels of cpt. curl's 16 bore double rifle in another thread but I don't know how that would work compared with standard Forsyth rifling.

I'm just trying to figure out the last little details before I order.

Thanks for all your help.
