Mostly Muir, my reloads have in the past been 'averagely' fine. Better than factory ammo. but with 'regular' flyers. Not so many regulars as to shake confidence in the load, but enough to make me wonder 'why'. Some weeks ago a friend who has a concentricity guage checked out some of my rounds and we discovered around 5% of the box exceeded the .002" recommendation - by a large margin.
So the project arose to look into how I set up my re-sizing die in the press, then adjusting the de-cap rod, finally looking at my bullet seating method and changing that.
Since making these changes, there's no doubt run-out on my reloads has improved, but prior to any of this, utilising the Lee expander (It's really a case mouth flaring die, not to be confused with the expander ball on a de-capping rod) & factory crimp dies had been discussed on this forum. The virtues of using these two dies extolled by yourself & others - I'm now awaiting arrival of the factory crimp die to find the additional value of including the two additional operations with my reloads.
I don't know anyone with a Forster 'Ultra' Comp. die in .25-06, so I'd have to buy one and as you know they're not cheap. Would it anyway perform better than my RCBS Comp. seater....while there is no doubt the Forster is a good die, why might I find it better than what I have?
Do you currently or have you used the RCBS Comp. seater dies & if so, in what way would you compare them with the Forster? Where would you believe are the differences in the two dies, that may make one die better than the other?
Earlier in this thread The Burpster agrees the RCBS product is good & consistent, but then says he 'upgraded' to Redding & Forster.....but not why he did so, or if the outcome improved. ATB
