Gentlemen,
I am not reloading ammo, but I was given a rifle and it was sighted in for me. I was supplied a box of ammo, however I never got the box. I was hoping someone could tell me how to figure out what grain bullet I have since it is sighted in dead accurate, and I want to stay with that grain. The round is 25-06 and the case head is stamped WW Super. Any suggestions?

Other than pulling a bullet & weighing it I don't know.

Two bullets of the same weight may act differently at range due to BC (ballistic coeffecient) or design differences.

Can you get in touch with the source of the rifle and ammo? If they are hand loads you want:
Bullet Weight, Make & Model
Powder & weight.
Primer, case & seating depth

You will have to find someone with a bullet puller and a scale. Pull the bullet, and drop it on the scale. Done.

Hpoe you didn't shoot all the bullets supplied to you. Might make it hard then......

they are not hand loads, I have the casing from the deer I shot and it's made by winchester. I have been looking on their website and I can only think it might be 115gr. But I guess I won't really know unless I can get in touch with the chairty that gave it to me. Thanks guys.

The GOOD news is that you've got a really great deer cartridge in the 25-06.

If it's a factory round you might try posting a pic of the cartridge. Winchester doesn't load a lot of diffrent 25/06 offerings some of which feature a couple unique projectiles

WW super makes me suspect the ammo is of an older vintage and there may not be a modern load that's comparable. If you can't get the exact load you'll need to resight the rifle for the new ammo as you'd be astounded how diffrent two loads can shoot even with the same bullet weight. As us habdloaders know well, powder, primer, COL and velocity can have a very dramatic effect on POI

As far as I know, the only .25-06 round currently produced by Winchester is the 115 grain Ballistic Silver Tip.

Win has 5 loads for 25/06 ranging from 85 to 120 grains

Take a few of your rounds over to the WTBN/Armory on base - I guarantee some of those guys have just what you're looking for in the way of measuring tools (scales, calipers, etc.). Semper Fi. Good luck.
