i have a lot of redding and rcbs. I bought a set of hornady for my 204 and they are sweet. I just bought a set of221 fireball and 260 rem redding and I am not to happy with either set. The 260 sizer has more chatter marks in the body and shoulder area than a file. The theads are very rough on all of them. They just went way downhill. I think I will buy hornady from now on.
RCBS and Lee cover most calibers and I can't tell the difference or have a desire for anything more. Maybe I am just in the wrong forum. Right now I have changed my focus to .22LR long range as a concession to advancing age and associated disabilities.
They all produce great ammo if you treat 'em well. I personally waven't gotten any crappy dies form any of them, but I had a remmy in 7rum with a loose enough chamber that it zipped open a set of redding and a set of rcbs dies; thought I had a bum set until it killed the next die, then a mic of the brass showed .555 at the heal, when max should have been .550 or less.
I have all but the Redding dies and in my opinion the Forster dies are the best, but dang! are they high. The Lee dies are really good too and the least expensive. I buy Lee dies for all the hunting loads I make for my friends. The Hornady equipment is terrible! Not just the dies , the trimmer and the scale I have are junk! The trimmer will not stay adjusted and the scale will not measure 46.0 gr. it will show 45.9 or 46.1 no matter how may times I try ( I'm using a trickler not a powder measure ). The Hornady die steel rusts as soon as you clean them up , Poor polishing = rough sizing and easy rusting. Hornady just sucks!
