Re: OCW Load development, .338LM
It's a 4 year old thread, and the OP hasn't been back to the site since late April. So, it may be a while before any more answers show up.
I wish he had shown more of his groups from day 1 so that I could see the progression as he increased the charge. Also, the added-in markings cover many of the handwritten charge numbers.
I'm hoping to try this with Dad's 7mm Wby so every time I can read someone else's report about the process I do so.
