Re: 7mm Ultra Mag loads??
I shot the 140 gr Nosler Ballistic Silvertips for several years out of my 7mm RUM. I used 95.5 gr of Retumbo lit by a Federal GM215M primer. This load shot really well, and made a load of one shot and drop kills. Seriously, don't think I ever shot an animal with those load that ever moved once it was hit, just dead right there. I'd have to check my load book for velocity, but I know it was somewhere in the 3450-3500fps range. Definitely work up to this load carefully, as your rifle may not handle the load exactly like mine does. Also, be very careful how low on the load range you start. This round does not do well at all with light loads, and tends to have detonation problems if the load density is too low. Hope this helps.
