I use 69gr. of Hodgdon H1000 in my 7mm WSM with a 160gr Nosler Accubond. Thing shoots lights out! My dad has a regular 7mm rem mag and uses the same powder and bullet and his shoots lights out too! The H1000 powder is a slower burning powder which reduces pressure in the case and it provides higher velocity's on magnums. With careful attention to detail and pressure of your exisiting loads, you can increase your powder charges and get even more speed if you want it.
I would HIGHLY recommend checking in to H1000 powder. It's extremely accurate powder and consistent with it's burn and velocity variances. Most powders including IMR4350 and IMR4831 have up too, and in excess of a 50 fps variance between loads and temperatures. The H1000 powder is less than 20 fps variance therefore producing more consistent grouping and loads. Just some food for thought there.
Oh, and as Phool mentioned, the Berger VLD 168gr bullets are great for long range shooting and have an excellent ballistic coefficient. One thing with that bullet, it's extremely finicky and may take some playing around with seating depths to get it shoot good in your gun. Most of the time with that bullet it needs to be touching, or almost touching the lands and grooves to shoot good groups. However, if you're shooting a gun with a clip, I can almost guarantee that with the bullet depth longer it won't fit in your clip. Good luck!
