I see a lot of data on amax 123's and other 120's and 123's but very little on the 123 SMK's, I picked up a box of 500 123 smk's and am looking for a good load to get me in the zip code of a starting load. I have Varget, H4350, IMR 4350, and 4064 to choose from on powders, I also have Lapua, SSA and Rem brass. It seems the 140's like to sit off the lands between 10 and 25 thou, is this also the case for the 123's?
