I have a T-7 on my bench, it is great (that and my Dillion are the only presses I bought new, out of 8). I set up a decaping die and leave it (you can use a sizeing die from a really large cartridge for this). I also like a press set up for Hornady lock-n-load bushings, of course Hornady makes a couple, but I like to buy used, RCBS Rock Chucker presses and put in a conversion bushing (I have 2 on my bench) Lyman makes a good turret press, the Mag-T. It is massive and well designed. Lyman's older turret press, the Spar-T is great for pistol rounds, but deflects some on Large cartridge sizeing. From my experiance, changeing tool heads leads to problems, you will need to reset them within 1 or 2 .001" or you'll start on the road of headspace difficulties. A friend of mine uses the Lock-n-Load system only. He sets dies with feeler guages, and then Loc-tites them in place and uses the same shell holder for that cartridge exclusively, and it is marked so. Normally you would have 1 shell holder for 45acp, 30-06, 270win, and 308win; he has 4 of the same one-each dedicated to one cartridge. I have seen him shoot 1" groups at 600 yards in light wind. The Bonanza/Forrester Co-ax press is also a great press for precission ammo, but won't handle longer dies. I hope all this help you make a informed choice. Ivan
