Problem solved

I changed ammo and everything is fine. Switched to a hornady boat tail spire point 180grn weatherby ammo and solved all my probs. Its drving tacks now. 100-400yds its pretty much hitting all the same. 500 yds I was hitting about 6" low. So Im ready to leave wednesday gonna be nice and cool in colorado. Oh yeah when I was finishing up shooting at 500yds I chambered one of the 180grn nosler partitions and shot it. It was in the dirt at about 100yds before the target. Ill never buy another nosler bullet.

Bud, I hate to tell ya. But if your hitting 6" low at 500 yards with that load, your problems are far from over. Kicking those numbers thru a ballistic Calculator, and having extensive experience with a 300RUM and Weatherby Mag and long range shooting, with a 180gr hornady with BC around .475, 6" low at 500 yards is 7.2" high at 100 and 11.2" high at 200, and 11.3" at 300, with -7" low at 500. Now this is figureing 1.5" scope ht. Quite an arch you got going. So if your being straight with us, I highly suggest you go back and see what you are doing at 100 and 200. Your going right over an elks back.

It ain't your Nosler bullets, its something else. Go out and buy you a copy of Quickload, or Sierra's software. You sound like you need it. I hate to see ya go out there and screw up on a short shot.

Maybe my range finder is off. I know know. It is shooting dang good and flat for me, I went back and shot it at 100 and it was prob. 4-5" high. Everything appeared perfect to me.

Ok, so you are saying your weatherby is doing something else that nobodies can do?

Even giving some and saying your 180gr is flying at 3500fps, which would be almost undoable even with a 30-378 Weatherby and 5" high at 100, you might get 6 or 7" low at 500. And You would be flying 8.5" high at 250yards.

Man, you sure your ready to go hunting? Are you sure your actually firing the gun? Are you sure your actually going hunting? Why in the world would someone want to have thier scope set 5" high at 100 yards?

I doubt Nosler has anything to do with it. Sounds like many years of practice are in order.

TexasAggieBowHunter:

If your rifle is set at 5" high at 100 yds., you are using what is called Maximum Point Blank Range (MPBR). According to "Ammo & Ballistics II a Hornady 180 gr. Pointed-Expanding bullet should be travling at 3240 f/s". I was not able to find a Weatherby 180 gr. BTSP factory ammo data, but I used the BC for a Hornady BTSP which is .452, and the velocity of 3240 f/s. If you are 5" high at 100 yds. at 200 yds. 7.9", at 229 yds. 8.0", at 300 yds. 6.4", at 400 yds. -4.0", at 465 yds. -8.0", and at 500 yds. -13.2". The kill zone (MPBR) on a Mature Bull Elk is 8.0". Which means your bullet can hit a mature bull elk 8.0" above the line of sight, and 8.0" below the line of sight, and you will be within the kill zone (MPBR). In theory, the way your rifle is sighted in your bullet will never travel higher than 8.0" high, but it will hit -8.0" at 465 yds., so you will have to compensate after 465 yds. If you see a Mature Bull Elk at 500 yds., you aim at the top of his back, and the bullet will drop into the kill zone. You must remember this is not exact because you are not shooting in a controlled enviorment (at sea level, no wind, flat terrain, etc.), and you do not know your actuall velocity. For this all to come together you must go to the range and test your rifle and your skill.

I use MPBR , but I use 7.0" for my MPBR on elk. Good luck.

Handloader, you forgot to take in the effect of someting called accuracy. At 500 yards, a man is real lucky to get 6" groups. Thats a good gun. So you take your MPBR, throw in that, and then throw in field conditions. You probably decreased your kill area to 3". And thats generous. Guess what? Thats around a 250 yard zero. Probably a personal limit people should be responsible and set on themselfs to be an ethical hunter. Just an opinion. No wonder I hear of some manypeople shooting over elks backs.

I wonder why people don't get a Mil-Dot scope if they plan something like this. Or the new B&C recticles. At least your not guessing with these as much.
