As cockercas says, it will by pretty much the same as it is at 100, perhaps a 1/4" higher at 50... If you can tell me bullet weight and MV I will be able to give you an accurate answer.

MiLisCer Posted April 11, 2012 Report Share Posted April 11, 2012 If you are using 140gr bullets @ 2500 fps - you zero should in theory be around the 140 yard mark (1" high at 100) - this would give you in theory a shot 0.61" high at 50 yards. Try it and see though - I am not a fan of 1" high at 100 yards - but if it works for you. Mike Quote Link to comment Share on other sites More sharing options...

Mike Its just the way I was taught many years ago so have always used it. as you can tell I am not really into the ballistics more as you say what works for me, Its something that I should spend some time on.

al4x Posted April 12, 2012 Report Share Posted April 12, 2012 Doc not doubting things but at 50 yards is it worth wasting the ammo :unsure: or is it to scare the lr users there Quote Link to comment Share on other sites More sharing options...

Vince Green Posted April 14, 2012 Report Share Posted April 14, 2012 (edited) Difference between 50 and 100yds for a load like that is probably less than you can measure. About one quarter to a half a gnats boll0ck. give or take. Shoot it and find out Edited April 14, 2012 by Vince Green Quote Link to comment Share on other sites More sharing options...
Dekers Posted April 15, 2012 Report Share Posted April 15, 2012 (edited) I have just joined Christchurch gun club but they only have a 50yds range, my Sako 85 6.5x 55 is zeroed at 100yds 1 " high where will the bullet be at 50 yds using federal premium A couple of shots at 50 yards will give you a more accurate answer than anyone can tell you here! My thoughts are that it will be quite close to its first zero point. Edited April 15, 2012 by Dekers Quote Link to comment Share on other sites More sharing options...
Vipa Posted April 15, 2012 Report Share Posted April 15, 2012 140gr sorry should have put that in depending on MV approx .5" high at 50yds (that is based on 2,500fps) Quote Link to comment Share on other sites More sharing options...
