forster 308 full length sizing die

[s1rk1118]

Building a new 308 for F/tr. I will be ordering dies and have had very good results using Forster with my 6.5x47. I would like to know what the neck dia is on the 308 flsd so I know how much to neck turn and also for bushing dia choices. The reamer I will be using has a 341 dia neck and I will be using Lapua brass. On my 6.5x47, after neck turning, all I had to do to a fired case was run it through the full length die and then an expander mandrel and came out with .0015 neck tension (I may have just gotten lucky there) without using bushings.

You never know when a company might change a dimension, but the Forster FL .308 die that I use has a 0.332" neck.

I use it with Winchester or Western brass turned to 0.125" for a 0.333" loaded diameter in a 0.336" chamber neck. Works great!
