Way too many years ago, I started reloading on a Lyman Spar-T press. It worked fine for me. So, when I got back into reloading a couple of years ago, I naturally bought a T-Mag. I was surprised to see that over the years, the primer feed system had been moved from the frame to the turret itself. Whoever thought that was a good idea should be ... um, fired. Whereas the old Spar-T primer feed system worked well (as I recall) the new design proved unusable. I was spending more time chasing spilled primers than reloading. I quickly gave up and went back to manually placing primers in the cup.
Ultimately, though, I switched to an RCBS hand priming system which gives me a much better control over primer seating depth and so on. It is almost foolproof, and very fast to do a batch of cases.
I still use the turret press to do case-mouth flaring, charging, bullet seating, and crimping in one go.
And if I read JUST ONE MORE THREAD about how great the Lee Classic Turret Press is, I'm going to lose all self control and rush out and buy one!
