Question by jobguy. Uploaded on October 20, 2009
If you sight in at 25 yards you should be about 2.1" high at 50 yards, and dead on at 300 yards.
Sighting in at 50 yards will give you a much flatter trajectory out to 200 yards.
FYI, you can calculate these using the JBM Ballistics trajectory calculator.
Good post from Husky... in addition, I would suggest testing your rifle and load at these distances so you know for certain. The height of your scope makes a big difference in the close range impact point and some scope mounts on that rig are set pretty high so you can see better through the scope. Also, the speed of your bullet makes a difference too. I shoot very fast (3450 fps) 50g bullets at varmints and they are a little flatter than this.
Husky- excellent post & data. Ditto on what Dakota said too.
jobguy -I'd add that while this data is important, it would behoove you to actually put lead-to-paper and verify the results from your gun and particular bullet weight/velocity. If you change bullet weight/charge or if you change brands or bullet types of factory ammo, all this changes.
I keep a notebook of all loads and such for every gun I have. If you do any experimenting, you will probably find that your gun will favor a particular load/factory round combination. If you are really lucky it will do well with multiple bullet weights and loads.
