Thread: .308 flattening primers

it never fail to amaze me in this modern internet enlightened enviroment that folk who reload STILL DONT READ A MANUAL....... you have a load from a manual....most if not all have a start load and a maximum load....you ARE SUPPOSED to start low and work your way up....UNTILL you know rifle and what it likes/doesnt like.....nearly EVERY reloading manual will have two cautions in it
nearly every source of reloading data will have the same two warnings

data was safe in test rifle...all rifles are different
start low and work up.

a good example of this is my .270 Vs RUMPYs one....his loads would be fine in mine...my loads would quite likely blow his rifle up..... my rifle HAPPILY sits 2grns above maximum of most manuals.......his flattens primers and gets sticky bolt 1-2grns BELOW MAX....
his has short throat...mine has longthroat and what appears to be a loose barrel..both shoot sub moa and both kill animals.

Hey Micky Duck

Thanks for the input.

I have loaded from min to max load for 5 different projectiles for this rifle. I have cross referenced the ADI reloading manual with the projectile manufactures load data and also cross checked powder equivalents used in the projectile manufactures load data with the adi powder equivalents information.

It’s certainly not a lack of caution or reasearch that has prompted my question, I merely noticed that my primers were a bit flatter with these loads than the 42.5gr of 2206h that was behind the 165gr loads I was making for my rem 700 .308

I’ve also had no sticky bolt lifts with this load, only when I have previously neck sized instead of FL sized.

Thanks for the input from everyone. I’ve settled on a load that will do the job for me.
