Sighting question
 
I just purchased a new scope and hope to sight my 308 this weekend. The issue is, the range I use only has a 50 yard target not a 100 yard.

If I dail it in at 50 yards, is your opinion I should be good out to 100? The longest we generally shoot at game is about 100 yards where I hunt and usually under that. Just want to get a feeling of confidence with sighting on a shorter range.

You need a bullet drop table for your load.

Generally, shooting a 150-gr bullet at 2800 fps, you can zero at 30 yards and be on at 200.

Just get a table for your specs and calc it out.

It's going to vary by several factors including distance between center of bore and center of scope, velocity, bullet weight etc. I think you'll find that dead on at 50 should yield you about an inch high at 100.

You can get it pretty well sighted in from 50 yards but if you want to test out different bullets and how they shoot I would go to 100 yards. 50 yards is a tad close to really see how the bullet will perform as far as down rave accuracy.

I'd find a 100 yrd range and do myself and my game a service by knowing my proficient range.

+1...tested more than once when back in the day all I had access to was a 50 yard range myself.

But if you practice at 100 yards, you're only going to be proficient at 100 yards...

Point being , any flaw will be magnified at extended range. Maybe that's what I should have typed. The further range you can dial in a rifle the better off you will be.

I agree... he said his max shot is 100yds ,if sighted in 1/2 high at 50 that bullet is not going to move much at 100 i dont care what brand ,gr etc..your shooting. If you were hunting out west where you have a shot out past 200-300 than yes you better start getting more technical with your ballistics.. and find a range to practice at those distances.....
