Was looking around Midway when I came across this

https://www.midwayusa.com/product/197053/lyman-msr-precision-4-die-system

I have no experience with Lyman dies, but I really like that the dies are black oxide coated and it comes with a case gauge.

looks like a nice set!

"The black finish matches your rifle" is really grasping for a sales pitch, but I like the fact that it includes a chamber fit gauge. They obviously did their homework.

honestly a SB die for this caliber seems a bit much.

i can understand the need for one when normalizing military brass that may have been fired in a MG like 5.56 or 7.62 .... but for a caliber like this it seems.... excessive. My concern is over working the brass and shortening the longevity of it.

Actually I modded one of my shell holders (cheaper than an entire die) to allow the resizing die to come down a little further and it made some cases with too much growth, chamber again in my AR based upper, where they used to bind a little bit going in.

How you do that?

I carefully chucked it in my lathe, making sure it was trued and using a carbide insert tool, shaved it down as far as I could go and still have a reasonable amount of "meat" left. I don't have it at work with me but IIRC, I shortened it something like .075 or so. By pushing the case further up into the resizing die, I get a little more neck tension for my trouble as well. Not leaps and bounds of difference, but I could feel it when I seated a bullet. A lesser degree of the old TightNeck experiment, from back in 2012. Visually, its easy to tell it from an un-modded one, so you don't mix them up.

About the only way I could do that would be to just rub it on the side walk at work and hope for the best.

I like it because it comes with the "M" Die and the case gauge, for the same money as Hornady.

The Lyman die set requires no case lube? Is it worth the extra money or just go with lee 4 die set.
