XXL Discussion Group

Hi All,

I have input all of my details into the load data, such as case capacity, trim length, barrel length, twist rate, etc, etc. Once done I chose Viht N555, it then recommended 40.0 grains of N555, whilst I carried out a ladder test I settled on 41.5g.

Having re looked at the information churned out by XXL, the FPS was nearly bang on.

My question is, is it worth re visiting and adjusting the seating depth? How good/accurate is this information that's churned out.

Appreciate any comments.

Thank you
