I am having a custom job done and have selected a Pre-64 action and PacNor barrel or krieger. I am kinda stuck on wether to go with a 10" or 12" twist rate. As I have grown to respect the wealth of knowledge on this Board; what do you all think is the better of the two? I am leaning to 12 as I have no interest in launching anything heavier than 225 gr. so was thinking the 12" would be better. The 210 Nosler probably be my go to bullet with the 225 Hornday as second choice.
