Greetings,
caliber 30-06
Powder big game 56.6 grains (way under maximum load that is 59.2 or 60.7)
Primers Winchester rifle magnum
Brass FC
Bullets Sierra Pro-hunter 150 grains and Hornady 150 FMJ and M1 Ball 147 grains
I shoot those in my savage model 10 and everything is ok. Sometimes I got a bolt a little bit hard to close because I size on the tight side.
I shoot those in my Howa 1500 and the rounds loaded with Sierra Pro-Hunter show MAJOR signs of over pressure: cratered primers, hard to open bolt. BUT THE OTHER rounds with the other bullets do not show any sign of pressure in that rifle.
Anyone got an explanation? I have a couple of ideas, but I want to hear from you before guys. It is the first time I get something like that in all those years of handloading.
Thank you
