If you change dies from one brand to another how likely is the possibility of having to change loads. I was using lee dies when I first got my 243. Had them borrowed and finally got some rcbs. I done a few things to the gun and got a new stock. Loads that shot great before the new stock trigger still don't shoot well. I'll probably get it bedded after turkey season. But do the dies make that much of a difference that you may have to tweak a proven load.
