I had a custom rifle built and a recipe for loads made up. Gun is a 300WSM, recipe is for 185gr Berger VLDs. I was going to get my 300WSM dies, but a friend told me that Berger requires a "special die" as they are longer bullets. Anyone heard of this? The maker insists that my friend is full of crapola, as he just uses the standard 300WSM die from RCBS.
