.308 drop

[Leadmaster]

I used the hand loads.com site and it came up like this, I'm wondering if that means it drops 460 inches at 1000 yards or am I reading it wrong? I put in all the correct data for the 175 grain Prvi FMJ-BT with a 25 yard zero.

Range Velocity Impact Drop
0 2592 0 0
100 2412 -2.06 2.96
200 2243 -10.13 11.94
300 2081 -25.15 27.86
400 1926 -48.23 51.84
500 1779 -80.72 85.24
600 1641 -124.22 129.64
700 1512 -180.65 186.97
800 1395 -252.25 259.48
900 1291 -341.66 349.79
1000 1201 -451.8 460.83


oh and I guess it would have been helpful for me to say I'm using a scope with 1/4 moa clicks.

460" sounds like a lot. Looks like you are zeroed at 0 yards. With my 175gr loads I am at 360" drop when zeroed at 100yd.

But drop has nothing to do with accuracy because it can be accounted for.

Short answer: It depends on the velocity, air temp, humidity, barometric pressure and altitude.

Short answer?

Depends on his velocity. On my rifle with a 22" rifle, I'm at 403 inches/42 TMOA drop for 1000 yard with 175gr FGMM. I can get less drop, of course, with handloads pushing much higher velocities.

Maybe? You'll need to be at least an inch high at 25yds to zero at 100yds. Set the table for a 100 or 200yd zero. Then you'll have something you can use when you get it zeroed. 25yds is boresighted; not zeroed.

Does anyone know what the iron sight height is of an M1A?
