Due to chemotherapy and an injury that I sustained close to 50 years ago I can no longer use my 550B comfortably. The reason is that I no longer can stand comfortably and need to sit. I find that I cannot seat a primer as it is now painful to my lower spine to do this. I am looking @ finding a reloader that primes on the upswing if possible or the machine doing much of the work. The Hornady look's promising, any recommendations? The other thing is to prime off of my Dillion such like a co-ax.
