Well, I decided to go with the 7mm Remington Magnum for a variety of reasons. What I would like to know, what is realistic speed I should expect in a 7mm Rem Mag, shooting 150 grain Nosler Ballistic Tips in a 26 inch barrel. Gun will be custom Remington 700, Broughton barrel.
I used to use nothing but Norma MRP. Once I ran out of that I've been using RL22. Seat the bullet out as far as your chamber and magazine will allow to increase your net case capacity.
As usual just my $.02 Paul K

Correct!! A lot of current manuals give 7mm Rem Mag. loads that essentially make a 7X57mm out of the 7 Rem. Mag. It may be that there are indiviudual rifles which are not safely capable of anything more, but most are!
Just develop your loads carefully, and use slow powders like RE 22, H4831, and IMR 7828. You will probably not be disappointed.

I could generally count on a chronographed 3100 fps. with 150 gr. bullets, 3000 fps. with 160 gr. bullets, and 2900 fps, with 175 gr. bullets out of a 7mm Rem. Mag. with a 24" bbl. Some extra-fast rifles would had between 50 and 100 fps. to those numbers, but those loads were at the absolute max, and likely too hot to really be safe.........
