Sorry Mark, I picked up on an old thread regarding this topic. Pete may not be following this.
I found some Bertram brass in .284 win, I'm going to give that a try, I have read reviews from F class shooters in Australia that reckon it's ok, slightly smaller internal volume and slightly larger range in weight than lapua 6.5 284 brass. Otherwise very good.
Much the same price. See how goes.
Mark's method is what I have been using. Worked well for me.
