Lyman Pro Carbide Trim Die Features The Lyman Pro Carbide Trim Die is built from stainless steel giving it the durability to hold up to repeated use on the reloading bench without wearing out. Made in the USA to Lyman s own quality standards it is designed specifically for trimming .308 Win brass to a consistent length. The bottom of the die is threaded 7/8-14 the universal standard that fits Lyman Mark 7 and virtually every other reloading press on the market. This broad compatibility means reloaders do not need a dedicated press just to use this die. The top of the die carries a 13/16-20 thread allowing it to work with Lyman s new press mounted trimmer as well as many other popular press mounted trimmers already on the market. This flexibility lets a reloader integrate the die into whatever trimming setup they already run. Consistent case length is important for reliable chambering and uniform neck tension both of which affect accuracy downrange.
