Re: Match dies verses standard dies?
Common dies are much better than is commonly believed. You can easily pay for much more than you get, especially so for so called "premium" dies other than Redding/Forster. And even then it's a special rifle and shooter that will be able to see any real difference in the ammo.
Get yourself a concentricity gage first so you can actually see if you have a runout problem or not. And, if so, where it's coming from. No seater can make straight ammo if the sized necks are't straight!
The nice phone lady claiming "tigher tolerances" for her company's dies had to be repeating what she was told but it's meaningless. SAAMI tolerances are a range, minimum and maximum, for each dimension. Anything inside those tolerances are fully within tolerance, period.
No one could tell you if the various dimensions would load better for your rifle if they were held closer to the min or max. Nor would it be reliavant anyway, our chambers are reamed to the same kind of tolerances. If we get a perfect match it's pure luck, not the brand or price of the dies! What makes some dies - Forster/Redding - work a little better, on average, than the others is the design, not the tolerances.
Micro-adjustable seating heads are modest user convienences but they don't automatically do a thing for making better ammo.
I can't figger how any seating die could produce a less consistant OAL than others, it's all done metal to metal. OAL inconsistancy is much more likely due to inconsistant press operation than a die.
