Thread: 6.5 PRC Load Development Begins

You don't want to be right on the verge of pressure as on a hot day you could still be asking for trouble.
Possible issues include the action or bolt suffering catastrophic failure (right next to your face)
You will trash your very expensive and hard to obtain brass in very quick order either by case head seperation or by flogging out the primer pockets.
Seriously you might lose 100fps but what difference will that make ? How far out do you need to shoot this ? If 100fps is a game changer maybe you have the wrong caliber.
I used to be like this trying to squeeze every last fps out of my wsm calibers but in reality it just fucks things quicker and in some situations is down right dangerous.
That's my 2 cents, no more lectures promise no hate just genuine concern

It had no pressure signs at all at 60.2, and even 60.4 was minor so somewhere between the two seems sensible? I want to get the most out of it without blowing my face off
Hornady brass gets ejector marks as soon as you look at it so its not the best to go by but 60.6 was definitely too hot
