Is this a load of bull?

[CNYCacher]

etch-a-sketch, etc

Ha! Got the point across though, right?

No that was free-hand with The Gimp.

I drew the targets with etch-a-sketch

The bullet might still be on the rise at 100 yards, then be coming down again at 300. That is not unreasonable. That is why heavier bullets shoot high - recoil.

A little knowledge is a dangerous thing. Again with a normal setup it is not possible. Sure put the scope a foot above the gun it might be.

Yet your chart has it zeroing at both 60 and 100 yards...

IOW, you just proved yourself wrong.

That is, of course, assuming I read that chart correctly.

 

[Charles S]

The guy said he was going to zero it at 100 yards. OK. He then said that the ballistics of the round were such that it would be zeroed again at 300 yards. I thought about asking him what the POI would be at 200...

Assuming the POI would be maybe 1-1/2 low at 200, muzzle velocity being 2700 fps per his claim, how could the bullet then rise again?

Interesting logic....????

Again, it is impossible for a Encore Handgun with any normal setup in 338 Federal to be zeroed in such a manner that the zero is 100 and 300 yards.

I honestly doubt you could set up any rifle in any hunting caliber that way, but I have never run the numbers.

If everything is on a level playing field, you are correct it is not going to happen.

I guess if you were shooting off of a bench at 3' in height and your target was at 4' feet at 100' and the one at 300' was similar you might be able to adjust it so all will work out.

Hills and valleys come into the situation when hunting if you are talking great distance it is a huge factor.

Charles,

I misunderstood you. I thought you were trying to prove that zeroing twice was not possible. I get it now, you were proving that zeroing twice at 100 and 300 yards was not possible. My bad.
