I have a ton of old 50 gr sx and 60 gr sp, recently purchased an r15 wondering about the twist rate for the sx's, but would really like to use them if someone has any experience. Data on both bullets is a little hard to find (don't have a hornady book). Thanks
 
If the 'SX' are the old Hornady Super Explosive, the box usually gives a maximum velocity that they will work...If my memory is correct, it was about 3200 fps...Normally they will shoot in most normal barrel twist rates until you get into the 1/7 area...Just approach your charge weights conservatively...

The Soft Points should be good to go unless they are designated as explosive as well...
 
Thanks, I'm gonna be starting around 2800 so I should be in great shape. If anyone has a load for the sx's it would b greatly appreciated!
