After a 6 mo wait I finally got mine. I have a factory rem 308vtr and imagined this die would be lots better than my lee collet in combo with the redding body die. I thought I'd get 2 benefits....one would be my casing would grow to fit the chamber better and the other would be really ez no lube sizing. What's happening is the die doesn't size all the way to the bottom of the neck. Being a factory chamber the case mouth opens quite a bit after firing and when the busing sizes it back it leaves a pretty good bulge at the bottom approx .060" of the neck. I thought this might be ok in that it would also help center the casing in the chamber better after sizing. What I'm finding is that it chambers pretty decent but I have to give the bolt a pretty good tug after firing to get the brass out. I'm thinking it's hanging up by that bulge. I can see that if I had a custom chamber with tight neck this thing would be the cats meow but I'm wondering how good it will be with a factory chamber. On the good side I've actually used it with the lee collet die to just bump the shoulder and not size the neck.....still don't have to clean up lube and have a casing that better fits the chamber. I'm not sure how many firings I'll get before the body die has to come out again....maybe one or two with potent loads. ANYHOW....IF anyone else is using one please let me know what you think of my first impressions and any tricks you've used to make it a better die for you.
