I load 180 grain Nosler Accubond bullets in a 300 wsm. I now have two manuals. I know there is a differance in the test rifles for both manuals, but the data is different for the powder I am loading with. According to my Nosler manuel the load I am shooting is 2 grains over max and traveling approx. 3200 fps. but according to the Hornady data it is not quite a max load and traveling approx. 3000 fps. Is this because the Nosler leads have a differnt pressure build up than the Hornady leads? The pressures seem to be fine in my rifle. Anyhow, the load is extreamly accurate and devestating on Elk.

If you aren't having any problems then I wouldn't worry about it. If it ain't broke then don't fix it.

I wouldn't worry about it if Hornady says it is right. One thing, if you have a friend with a chronograph, you might want to get an accurate determination of your Muzzle Velocity. With that information, you can more accurately determine your trajectory and probably increase your probability of successful contact with your target. The faster your bullet at muzzle will likely give you a flatter trajectory. Good luck.
