I'll second that emotion!
Every Sendero, no matter what the caliber, has always shot exceptional, needing little if any work to get it there. Now, enter the 7STW into the arena, and it even shoots better. I simply never thought that any round with as much horsepower as the STW, could ever shoot as good as it does, EVEN in a Sendero. But it does, and with a lot of class too! these guns are keepers for **** sure!
As far as brass goes, I think fire forming is the best way to go at this point. I really want to get some Norma HH brass and work it out. I've been watching the gun shows recently. I'll find some !
