    So I'm new here and love what I've read so far. So here's something that's been rolling around my head... I have a 30.06 and primarily shoot 150 grain rounds I picked up some 165 grain rounds that were on clearance the other day and shot them. I had to move up 12 clicks to be on in elevation at 100 yards. The question is two parts: 1.) should I be on at 200,300 if I am at the same elevation at 100 yards with the 165's as I am with the 150's assuming they drop at the same rate? 2.) If I were to buy 180's would there be any way to know how to adjust w/o shooting ie. has someone done this who can tell me approx. how much lower a 180 grain bullet will strike at 200 yards then a 150 grain? Thanks for the comments. Don't rip me too bad, I'm new.

    150 or 165gr

    Take a look at what just happend You had to move up how far.
    What I have found is dont go by any chart.
    150 for the most part will not shoot the same as 165s.Close but no candy bar!!!!!!
    If you shot a 150gr win pp and a 150gr rem cl in your rifle the POI may not be the same. Bullet drop will change Even if thay both left the end of the barrle at 2850fps when the bullet gets to 100 200 and 300 the Droop will not be the same. The bullet may also be dead on OR hit off to one side,
    THE BEST Thing is take what ever 150,165,180, your going to shoot and start at 100 and move out and find out whats going on.To make it more fun ya may find that each brand of bullet may or will have a mind of its own thats the fun part. good luck :smileeek:

    Ballistic charts will give you a good idea as to the trajectory of your bullet but will not necessarily be the same for all brands of ammo. There are several variables you have to deal with; ammo manufacturer, bullet weight, rifle barrel length, even terrain and wind factors. If you reload, you can overcome some of the differences of powder charges. My experience of 150 gr vs 168 gr; the 168 gr presents about a half to three quarters inch drop from POA of the 150 gr. That certainly should not require 12 clicks on your scope. (I know you're asking about the 165 gr but I've gotten basically the same results with 165/168). I must add that I shoot predominantly Remington Cor-Lok.

    BTW, Welcome to the forum.
