It appears this seating die does the job of seating SWC boolits pretty accurately vs the flat stem approach on my RCBS and Hornady New Dimiension die set approach.
Not sure that sliding sleeve on Hornady does much , I think it just makes you feel good. I see no better seating results than the RCBS stem.
I mention this only because I find the odd round in a box of ammo that does not drop perfectly into my case gauge (45ACP) and that round is the one that the bullet did not seat true. Its the round that will slow magazine follower function and give rise to faulty feeding issues which as you know can be hard to diagnose at times. When you get that odd fail to feed, you chase recoil spring, magazine, extractor, load, ramp and barrel issues. You can chase all of that and the issue is really your bullets tilted on seating just enough to give you feeding issues.
I am thinking this Dillon die approach may be the answer. Besides, you can clean the seating die of lube deposits and never lose the settings of die installed on your case head (for progressive presses).
Your thoughts please on this.
