Re: lymans tmag II or rcbs rockchuckar??
I have no experience with the Lyman but have been using my original Rockchucker for 25 years without a hitch. It has produced 10's of thousands of rifle and pistol ammo and is still going strong with its original parts.
Eventually, RCBS did make an improved primer arm for the Rockchucker. When I tried to order one they wouldn't take my money, and just sent it along for free.
