I use a Lee Classic cast turret press. Sometimes a spent primer can bounce off the priming arm and lands on the floor. No biggie, I just shop vac my work area.
I have only been reloading for about 1.5 years and been using the press to prime.
You may have to just be creative with your press. For example, the primer catch tube on the Lee press that I have is long and can easily be hit by my leg and spent primers can spill.
I recently lost the tube and I called Lee and the tube is cheap but they'll charge me for shipping and handling which is more expensive than the part. I just went to HD and hit a 1/2 tube and made my own catch tube with a home made plug. I also made it shorter so that I won't hit with my leg by accident.
