I am in serious need of help on a 300 blackout load. I have two molds.....a RCBS 2-Cavity Bullet Mold 7.62mm-130-SPL 7.62 mm GC, and a NOE 311 247Gr. FN GC. Still need loads for these two molds.
The problem is I am scared to try them.....as the first 3 loads with j-word bullets have blown primers (thats putting it mildly)
The load I was thinking would be a no brainer was Hodgdon load of a 130 gr bullet over 17.9 gr of 296/H110. Tried both powders. (this load actually blew the bottom of my mag out) Seated with an OAL of 2.165. Loaded in mag and chambered well. I have read many times not to reduce 296/H110 because of preasure issues. Don't know which way to go with this.
I also tried a load with LilGun again at starting load with the same results.
The brass is reformed and annealed LC brass I ordered from GRUMPA here on CB. Using Winchester small rifle primers. I'm at a loss, any help would be appreciated.
