You're better off with 568. Ive been wanting to try 568 but I'm easily pushing 245s W/N570 @2930 tru a 26" with exceptional precision. My ladder took me to just past 3K but the node was at 2930.
Also consider N170
In Texas I've been on a lot of work trips stopping into LGS and seeing overall higher prices on powder but I've been scoring normal prices on 210m and 215m
I.e. $80 for a lb of varget but $11 per 100 of 210Ms
They seem to be legitimate. I had YouTubed what's going on in the primer/powder world and their inventory video from a few weeks ago popped up. Their YT channel is active.
