I am looking for a trajectory chart/table for a 150gr .308 Winchester. In particular, I am using factory 150gr .308 core locts loads. Whatever you can give me that is at least close to this loading is appreciated. I will be shooting up to 400-500 yards with a Winchester Model 70 with a 22 inch barrel. Thanks.

I think CoreLokt is Remington, but they dont seem to have much trajectory or ballistics information on their site.

Here is the information for the Winchester SuperX 150 grain pointed soft point. This should be a pretty similar load and I believe that this information is with a 24" barrel.

In case that link doesnt work for you, here is the executive summary:

Muzzle velocity is 2820. Velocity at 400yds is 1633fps & 500yds is 1405fps.

With a 200yard zero, you are are 2.5" high at 100 yards, 10" low at 300, 29" low at 400, 62" low at 500.

Hope that helps.

This is from Remingon. Go to their home page then, Products, Ammunition, Ballistics and you can compare cartridges. As I feared, the table didn't paste too well over here.
