Re: #7 barrel contour
I have an oby #9 blank here. It's a 25" blank, and weighs 6.5 pounds.
Keep in mind it's not chambered yet or anything. I expect to drop about half a pound because I want it to finish out about 22". I'm also going to have it fluted to drop about another 1/3rd of a pound.
*my mistake, the oby I had is a #9, not a #7
