Re: Redding T-7 or Forster Co-Ax
I sold a T-7 a while back and bought a Co-ax. I also replaced all my Redding dies with Forsters.
The T-7 will hold dies for 2-3 calibers, depending on what neck/FL dies you use. Any more than that, and you're back to swapping dies, or you buy another turret and fill it up with dies for 2-3 more calibers. I bought another turret with the T-7 I had, but I sold it unused with the press because swapping them out looked like a PITA to load a few rounds of ammo, and swapping a single die in a full turret is a real knuckle buster.
I have 7 calibers of dies on my bench. I can do any function on a single piece of brass in any of those calibers in 10 seconds and have the die back in the box and back on the shelf.
If you are loading a couple of calibers and intend to set up your dies and leave them in the press the T-7 will work fine. As far as "slop" in the turret, I could see movement in the turret when the ram put pressure on the die. I don't know if it was enough to cause problems, but it is there because the turret has to be able to rotate.
The "universal" shell holder on the Co-ax is excellent. The largest case I load for is a 7 WSM and it works fine. If you load .223's you'll need to reverse the jaws in the shell holder plate. That takes 3-5 minutes, depending on how many thumbs you are blessed with. I have several extra, so I bought a second Co-ax and set it up for the .223 loading.
The primer seating gizmo on top of the Co-ax is a little slow to use, but it seats every single primer perfectly. I don't load large quantities of ammo, so I'm not in a hurry anyway. I like it better than any other priming method I've ever used.
The Co-ax catches every single spent primer in the little cup underneath it. The tube on the T-7 catches most of them, but a few end up on the floor. That wasn't a problem for me because my bench is in the garage, but I wouldn't want them in the carpet or on the hardwood in the house.
One of the negatives that's often mentioned about the Co-ax is the fact that you can't use a bullet puller because you can't turn the handle. If you have dies in the T-7 turret you cant use the bullet puller because the handle hits the dies.
I'm not slamming the T-7 at all. It's a heavy duty piece of machinery. I just like the Co-ax a lot better.
I sure hope that helps answer some of your questions, because I've worn out 2 perfectly good fingers with all this typing.
