I posted this earlier in the tread, but in case you didnt see it, here it is again.
The go to load has been 25.70gr of Win 748 (from Ladder Testing), seated to 2.260, with CCI450 (needed to get 748 going). Cases are Lake City 16 sorted to 92.0-92.4gr. I shot several 10rd strings through my CED Chronograph with the following results (avg) 2888fps, STD = 7.7, ES 27. Rifle is a BCM with 20″barrel. Shoots pretty tight groups ~ 0.5-1.0MOA. Only negative is 748 is fairly dirty, but rifle functions just fine (based on thousands of these rounds through this rifle).
The load is fairly well known and has been published in a few places (Ziedker). It was actually 25.5gr, as published, with a 69gr SMK. I just did ladder testing and my node came out to be 25.70, but I did note that 25.40 was almost as good. If you use WIN 748 anywhere in that range you cant go wrong. FYI, Im using a scale with +/- 0.02gr accuracy and weight sorted fully prepped cases, and yes, it makes a difference.
