sighting in a rifle

[jared]

Hello,can someone help me I have just switched to a scope from iron sights,can you tell where a 7mm magnum should hit the target to be on at 200 yards.I sighted the gun in dead on at 50 yards and it is hitting 3 inches high at 100.PLEASE HELP

 p.s.  the email is not nasty,it is a softball nickname

You should be about 1 inch high at 200yards the way you got it now. Depending on the grain of bullet.

   Jared, I'll second what speedgoat said. Additionally, I'm sure that you're aware that you need to use the same brand of ammo, with the same bullet weight and type to maintain consistency with your point of impact.  Practice with the new scope, you will be amazed at how much more accurate you will be with it. Happy hunting.

And if you're not reloading (as Nathan implies) but you want to be anal retentive like a reloader, you should buy extra boxes of ammo from the same BATCH NUMBER.  I buy a box of ammo to sight in the gun after columnating it.   Then I go and by several boxes or even a case with the same batch lot so I can be relatively assured of equal performance.  Your 7mm is far from a favorite of mine but it is an extremely flat shooting round with plenty of umph when it get there.  Knowing what your round is going to do every time makes you just that much better of a shot.

Jared,  With mine I am shooting 1.5 high at 100, 1 in. high at 200, 0 at appx. 250.  I'm reloading my own ammo. Whatever you do though, make sure that you do not just look at the box of ammo and go by their specs. for bullet drop. I've seen alot of charts that are 6 or more inches off of what they said. Your rifle is different than their test rifle. If you are going to be making 200 yd. plus shot, make sure you test the ammo at that yardage. Do NOT go by what the factory says. It is just an approximate.  Have fun.  No matter what anyone says, the 7mm is a great caliber . It's all about the right type of bullet and placement. I've taken a walls worth of animals with it and it is pretty much the only rifle I carry now.

Great advice Sawtooth.  I see that a lot as well.  And you don't know HOW badly I'm resisting the bait you just threw out there about the 7mm being a "great caliber".  Please help me Lord, this post will go on forever if I say it.  LOL

[Sawtooth Taxidermy, Todd]

Hey George, Right after I said, in my post, that the 7mm was a great caliber I had a little sentence for you but I edited it out. I didn't want to pick the fight but was hoping you would take the bait and reply. LMAO. You did. Favorite rifles are like discussing politics or religion. I've never had a bad experience with mine and I use it for squirrels on up so for now she is my favorite. Take care.   Todd

[George Roof]

LMAO  Sawtooth, I like you.  We think similarly on this subject.  You're absolutely right.  I've always loved the .270 and the .300 Win Mag which sandwiches the 7mm in between for someone like me.  But I've always had this "glitch" about not liking any caliber, pistol or rifle, that had the silly assed metric system involved.  (I own a .243, a .30-06, .338, and .375 just to prove it.  LOL)

[Sawtooth Taxidermy, Todd]

Well then George it's easy. I'll start calling my 7mm a .284. Just for you. LOL  Have a good day    Todd

  George, just a little FYI; your firearm advice is always right on the money, and while I don't totally agree with your dislike of the 7mm, here's a little fuel for your fire; last year in Canada, I shot a whitetail buck slightly quartering away neatly on the shoulder crease at about 75 yds with a 160 gr nosler partition bullet, intending to take out both lungs, and break the off shoulder. To make a long story short, the deer ran off. Two days later, I shoot, and kill the same buck, complete with broken shoulder and two perforated lungs, which were turning necrotic. How that deer survived two days are a mystery to me. Maybe you're onto something with the 7, Elmer Keith would undoubtedly agree with you.

[Sawtooth Taxidermy, Todd]

Nathan, Can't blame that on the 7mm.  If you put the right bullet in the right place the animal goes down. I have 6 bull elk, 2 bears, and too many deer to count that I took with my 7mm. None went more than 30 yds. There is no reason that deer didn't go down if you hit it where you said. I would have to guess that the bullet didn't expand when it went into the animal ,leaving only bullet diameter holes in the lungs. That though can happen with any caliber or poor bullet selection.  If you reload, get some different bullets and keep shooting the 7.  Remember, for George, we now call it a .284. LOL

  Sawtooth, my 7mm remark was in jest. I have taken a 400lb bear, multiple whitetails and sitka blacktails, and a couple of 300lb mulies with mine, it is a great tool for the job. What happened last year was a freak occurrence, especially seeing as the projectile was a nosler partition bullet. If you hunt long enough, you will see strange things happen on occasion. I won't hesitate to pick up the 7 on my next western trip.
