Steve,
You should have your friend go to the following web site
http://www.redding-reloading.com/ and check out the Redding Turret Press. I've used one for years it's heavier than a Lyman turret. Concerning accuracy using a turret press. I'm not a benchrest shooter whose goal is to shoot one hole groups but my Redding Turret gives me ammo that will shoot 3/4" to 1" groups from 100 yards in 223, 243, 308 & 3006.
A turret is more convienent than a single stage press.
