Default Hornady 75GR BTHP W748 Load Data

didnt know if this powder and/or load data had been posted before, so ill post it


i came into a couple of pounds of winchester W748 awhile back, and decided to try it out.i looked and looked thru all of my manuals,etc for a 75GR BTHP match load, but couldnt find one anywere at all. i called hornady and spoke to one of there head techs down there who was very helpful. i explained to him i was wanting a load for 75gr match BTHP for my AR-15 and couldnt find any load data

he said
loading 75gr BTHP Match with W748
starting load-20.2gr
MAX LOAD-24gr


im going to throw some loads together here in awhile and head out the back door to my looooooooooong range shooting range and ill let you know how they shoot

Quickload says 24.8gr of 748 will get you just over 55,000 PSI when the bullet is seated to 2.25" OAL.
Don't be afraid to pass 24gr if you are not getting any pressure signs.

If you told me your barrel length, I could give you predicted velocities and pressures...
