dj,

Actually my rifle is a loose fitting factory Rem with a long throat. Also I'm using roomy brass. It all adds up.

You need to also understand the nature of RL17 and it's impregnated retardant. It kinda changes the rules. The powder is labeled "For Short Magnum Rifles".

I've been loading for over 30 years, and I understand and appreciate your concerns. I'm pretty well versed at finding pressure and backing off a couple grains. RL17 is something you have to work with to understand a little. It really takes the peak off the pressure curve. Well, that's what the experts say anyways, and I'm seeing it in application.
