Re: Powders for 7mm Remington Magnum
I went out and shot my 7 Rem Mag again yesterday. I loaded 3 rounds each of 72.5/73.0/73.5/ grain charges of H1000 with the 162 Amax, Fed 215 primer. At 73.5 grains I was at 3,068 fps.
I also loaded up 3 rounds each of 71.0/71.5 RE-25/162 SST's/ with Fed210M primer. At 71.5 I was at an average of 3,039 fps. Accuracy was still good but ES/SD were getting pretty bad though.
I think I will stay at the 70.5/RE-25/Fed210 primer combo, this averaged 2,950 fps for 5 shots and shot in the lows .4s at 100 yds.
I will also give the 72.5 -73.0 grain charge of H1000/Fed215 some more looking into as well. As the best accuracy was at 73 grains but the ES/SD were 48/24.4. The ES/SD at 72.5 grains was 10/5.2.
I didn't notice any signs of pressure with any of these loads. No heavy bolt lift, easy extraction, and the primers looked good.
I have a question for anyone. Do you need the throat set up on your chamber to shoot VLD bullets, are there different throat angles specific for these bullets? I have never really had any luck shooting them in any of my guns.
