RE: ammunition for 7mm
Looking at ballistics on paper won't tell you how it will perform in your rifle, only way is to find suitable ammo for the application then shoot it at ranges you intend to hunt. If your not ever going to shoot to 500 why even make it an issue? Instead look at what you will be shooting, then review the bullets design/intended use and match it up to your hunting.
For deer I like the Nosler Ballistic Tip. In my 7mm rem mag the 150gr groups better then the 140gr at distances longer then 200 yards, so the minimal loss in trajectory is far less of a concern then accuracy loss. In reality the difference of a few inches in drop means little, if your are practiced you will be able to compensate for the ballistics of yourload fired from your gun and accuracyshould rule the roost when looking at longer range shooting situations IMHO.
