Hey guys, I am having trouble with seating depth in my 300 win mag. I have a very long throat and need a bullet that is longer so it can be seated out to the lands. Any suggestions? I have tried the 190 SMK, and the 180 SST. The SST shot better but I think I can do a bit more with a longer bullet. The Barnes 180 XBT looks to have a good (bc) but I am not sure if it has a longer ogive.
