Re: 7mm Rem Mag - reloading advice please

I tested Ramshot Magnum a little in my 7mag with 168vlds. I got great accuracy at about 3000fps (better than half MOA at 333 yards). I loaded some more up for more testing but haven't had a chance to shoot them yet. Its burn rate is right between H-1000 and retumbo. I'd give it a shot if you already have some.

Thats sounds great. Do you remember how many grains of Magnum?

My best node was 72.5gr-73.5gr. This is over Berger's max (70.8gr) so work your way up slowly. 74.2 showed pressure signs in my rifle. These were shot in temps in the 40s. I don't know how temp sensitive this powder is as I have yet to test and have read contradictory results from really good to really bad. I'd start around 69gr and work your way up from there.

+1 on the 168's and Magnum, I think you like what you see there

71grn of H-1000,Federal 215 primer,168 Berger works good in all three of my 7 mm mag's. Little bit warm, but no signs of pressure! Later on if you decide,160 Sierra's work good in a 7 mag also. An old load of mine was 64grn of IMR 4350, CCI 250 mag primer, 168 Berger or 160 Sierra. Hope this helps!

No Varget, all others work well. I likeIMR 7828 in mine velocities and accuracies are consistent from 5 deg f, to 95 deg f. 1 in or better groups on a rest at 200 yds.

If your shooting this far I wouldn't use anything less then 160gr.

Nosler is coming out with some 168 and 175gr long range accubonds with very high bc at the end of july.

I use IMR-4831.
