I am with Koda here. Something's not adding up.It’s coming out of the gun 1.212.
Best I can tell, I get a stiff bolt closure about 1.218.
If I bumped it .003 out of the current length, it would be 1.209
Wouldn’t I be better off keeping it around the 1.215/6 mark?
If the brass is coming out of the gun after 3 firings at 1.212, the 1.218 number kind of doesn't matter. Kind of hard to diagnose over the internet without seeing the brass, velocity data, etc.
Are you sure on your numbers being accurate? Is there any primer dimpling that could affect the readings?
Are you sure the 1.218 number and getting stiff bolt close isn't a case of the brass not being sized enough and growing to 1.215/6 and now your bullets are contacting the rifling?
If it was my gun and loads and the fired brass is coming out at 1.212 I am going to adjust my sizing die until my brass reads 1.210 and if I get 1.209 I am not going to worry about it. Don't go crazy and get them down to 1.206 or anything like that. But 1.210/209 is where I would want to be. But that's just me.
