I know it differs with all weights, but approximately where does a .375 H&H hit at 25 yards when sighted in for 100 yards. Thanks.

You're ignoring a lot of variables, but it should be either dead on, or a hair low. Or thereabouts.

i'm certain, it depends on the rifle, scope, loads, scope height above bore.... fyi.. my m70 pf safari express with a 2 x 7 x 20mm redfield, with medium redfield rings shoots 2" hi at 50, 3/4" hi at 100 and 2" hi at 25....this with factory 270 gr federal premium softs...

Thanks and I know your right. I have absolute no experience with the 375, I'm just bore sighting and want to be on paper at 100 yards.

That is going to depend on several factors that may require the help from some of the members who have a ballistic program. Some factors include the BC of the bullet; the velocity of the bullet and the height of the sites or scope above the muzzle. My Speer Manual list some information for short ramge zero. Their 270gr has a BC of .429 their 285gr has a BC of .354and their 300gr solid has a BC of .262. I assume if you are going for a short range zero of 100yards you must be planning to use a 300gr bullet With the scope 1.5" above the bore with a muzzle velocity of 2600FPS the bullet starts -1.5" low it is at 0.0" at 50 yards it is at 0.0" at 100 yards and it is at -1.7" at 150 yards and it is -5.2 at 200 yards. Just guessing this would put the bullet 1/2 to 1" low at 25 yards with the above data. If you change to a 150 yard zero you would be .5" high at 50 yards 1.1" high at 100yards; 0.0" at 150 yards and -3.0" at 200 yards and -8.3" at 250 yards. I think a 150 yard zero would also be just about 0.0" at 25 yards. I hope this helps some.

Zero your rifle first at 25 yards. Make all the bullets go into one hole right on the money. Then move out to 100, 150, 200, 250 yards and I think what army aviator said will hold.

Refine your zero at the longer range where you want it.

for what you are doing here, just make it hit close to dead-on at 25 and you will be on paper at 100 and can then adjust accordingly.

For other uses, a good ballistic calculator is on the Norma site:

Norma

click on "ballistic" and then input the variables.

Most rifles need to be a little low at 25 yards, dead on will be sometimes 3-4 in. at 100. You just have to shoot it at 100+.
