I guess the bottom line is.... be aware that things can be different with the nosler brass.
JUst curious what the start load/vel was and when it was you started popping primers??
The listed max load is 77gr of RE22 for 180's in 300WinMag.
I started with 5% less,which is 73gr,and blew a primer at 75gr,the previous load of 74gr showed no signs of excessive pressure.I didn't get a velocity reading with these loads.I also have a 'recoil pressure guage',but that wasn't fitted either.(I know,I know,I know!):eek:
I have to say that this is a NEW rifle,Kimber 8400 Classic Select Grade,which apparently has a tight chamber also.There is minimum deflection in the brass,and the shoulder has only moved .002" from unfired brass.
I haven't had any problems with either Remington or Winchester brass in this rifle,that's why I'm suspecting that the Nosler brass is the culprit.
Where I read about the Nosler brass requiring that you have to use the Nosler start loads was in Petersons Rifle Shooter.
