I've got Forster seaters for my .308 Win and .260 Rem, had one for the 6PPC before that barrel went down the road. They seat very, very straight. I keep thinking I'll pick one up for my .30-06, but I get very consistent runout of less than .003" with my standard Redding .30-06 FL die set. If I were buying again I'd get the Forster, but then I couldn't seat cast boolits with the Forster either because the tolerances are too tight.
