Hi,

I had this post in "The Art of the Rifle" and realized it should be here.

I recently read that if one tries to make a "Reduced" load for a 7mm Rem Mag that it creates dangerously high chamber pressures.

My Nosler reloading manual says that a good starting load for a 150 grain ballistic tip bullet is 48 grains of IMR 4895 this gives a mv of 2780 fps according to the book.

If I wanted to say only put 46 or 45 grains of 4895 probably dropping velocity 100 fps or so would this create a dangerous c.u.p. pressure situation.
