65-66g of IMR 4350, Rem case, 9 1/2 primer, 140g Tripple shock .050 off the lands should give you 1/2"-1" groups in a gun that is bedded with the barrel floated. 61g of IMR 4350 with a 9 1/2 primer is 2975 fps, with 1 1/4" accuracy out of my gun...barely acceptable...I don't use this load.
R#22 with a CCI 250 will do both bullets(66-68g with the 140's, 65g with the 160's) but I did not get the extreme accuracy with speed as I did with these three loads, that is why I don't use it.
I shoot two loads with the 160's, 69g of R#25 with a Win Mag Primer(very important), bullet .050 off the lands 3050 fps.
Another load with the 160's is 70.0-71.0g of Retumbo with a Fed 215, 3100 fps(MAX in my rifle).
Please work up to these loads in your rifle, they are safe in mine, but rifles do differ and lot# of powder can vary 5%.
Tell your buddy to invest a little money and try some different powders. These loads really give a 7 Mag some serious accuracy combined with top speeds.
For deer, 72g of R#22 with a CCI250 with a 120g Tripple shock is 3500-3600 fps depending on the particular barrel with unbeliveable accuracy from a magnum, much smaller than 1/2" groups. We have yet to see a deer to stop this 120g 7mm Tripple shock bullet. It is hard to belive just how flat shooting this bullet at this speed out to 400 yards. We started shooting this load years ago when the old Nosler 120g Solid base was in production. Often the 120g Nosler did not penetrate the deer, but was laying dead right where it was standing. Again, work up to these loads in your rifle.
If you are loading for a friend, there are all kinds of land mines you can step on, be sure he is a really good friend or pass on the helping hand.
