There's a guy here in Vancouver who makes custom sporters (for his own entertainment) out of Ross rifles and I see him at the range on Thursdays when him and his friends hang out.
He even has one in 7mm Remington magnum.
He mounts scopes on his, but I don't know what he uses for bases. He's a retired Canadian forces armourer and gunsmith, so he makes anything he needs.
Oh yeah, I have a "Bubba" Ross M10 with a hacksawed-off barrel to 24 inches I think it is, and it was accurate enough with iron sights for me to kill my first deer with it.
Would probably be better if I had it crowned though!
