If you noticed the way I avoided the pressure question in my original post I only said "faster" cause I had no way of knowing if pressure was necessarily affected. In all honesty I was seeing 30-50fps difference but stated the lower range as to avoid going down as a campfire crazy.
I was glad when Jim stepped in with the 75 fps figure.
I know Jim is meticulous and shoots his 300 alot so I know I'm not ready for the looney farm yet.
I'm dealing with a bad family illness and won't get to the range for a while but do quite a bit of loading for a friend with a custom 7 mag and custom 7 stw....he writes down the velocity of every shot...I will have to watch trends.p
