Thread: 7mm mag 26" velocity

You need to be careful. Experience has taught me that ballistic programs are usually very accurate and if you don't get near to the results you expect it is usually data entry or a gear problem.

So, I had a problem recently with my 300wmag. It was shooting 7-10" high at 525 yards. Blamed the 'scope for not clicking properly so tore it off and replaced it. Same problem again. Soooo I chronographed the load.....75.5gr R22 & 180 grn Nosler BT I had estimated at 3000fps...real average velocity was 3155fps. So there was my 7" of elevation. Problem solved.

If we are going to shoot at long range (out to 600 yards for me), we owe it to the animals to get these things right.

Now I've got a good spare 'scope.
