The mag will take it way longer than you can seat the rn out. I've probably got my numbers confused I'll look tomorrow. I loaded the first bunch per Hornady manual specs for them my notes and reloading gear is elsewhere, hard to do it here at the house with my son being foreman constantly
Reloading specs?
OAL is not a "spec". It is determined by you, for your rifle. Mag lengths vary, as do chamber throats.
Seat your bullet very, very long and chamber it. If you get rifling marks on the bullet, seat another a bit deeper, and try again. Repeat until you don't get rifling marks. Note that OAL and load ammo at that length to test. Late, when you have a powder charge developed, come back to the OAL and try 10 thou longer and 10 thou shorter.
If you do a lot of shooting, you will find that throat erosion will require a gradual length change in ammo. My 308 ammo grows about 10 thou a year.
