I have been reloading .45acp for about a month with good results. I am now starting to reload 9mm and have some quesitons I didn't run into with the 45acp reloads.
1) I am loading 124gr. Montana gold JHP. The lymnan book has 125gr. JHP listed. I assume I can use these suggested starting grains, correct?
2) The schematic for 9x19 shows an OAL of 1.169, yet the tables show a much shorter OAL, 1.075 for 125gr. JHP. I'm assuming 1.075 is the absolute minimum, not recommended length, correct? (my research shows people seem to use 1.120 - 1.150 length for these bullets).
3) For each table of load recommendations by bullet weight, they have the letter in bold "BC" and "SD" what does this stand for?
Hope these quesitons are not too dumb, I really have done my research and could not find answers to these questions.
