Re: Powder charge for 7mm Remington Magnum using 168 vld
I emailed Berger, and here is the information from Quickload:
Start Max load density
168 Grain RETUMBO 66.0 2839 70.4 3022 104.7%
I've collected some posts, and here is the synopsis of that combo:
74.9 gr Retumbo, 168 Berger VLD, Federal GM210M primers - my load in my 7mm Rem Mag rifle. My barrel is 24 2/8" long and my MV = 3080 fps.
Bullets loaded 0.006" into the lands shoot very well for me. I've never tried the VLDs backed off the lands as they shoot very well loaded into them.
Berger recommends into the lands or at least at the lands. I tried this and found the 168 did well. It did even better with about 10 thou off lands.
I shoot 168 VLD and 71 grains of retumbo. 3040 fps @ 4800 asl
excellent accuracy in my Sendero....
For what it's worth, out of 26" Hart barreled Sendero 7mm Rem Mag, getting very good accuracy (consistent 1/2 MOA or better) with 168 Berger VLD @ 3065 fps with 72 grains Retumbo, WW brass, and Fed 215 primers. Very consistent velocity spreads after barrel break in. One cool thing I noticed was that as the barrel got more rounds through it, velocity increased a little bit, then leveled off.
73.0 gr of Retumbo is safe in my rifle but 72.5 and 72.0 shot best.
If you like your hunting rifle, you can keep your hunting rifle.
