Re: 50 bmg bullet drop
need a bit more info like:
barometric pressure
air temp
bullets ballistic coefficient(or at least the bullet manufacturer)
what do you want the drop to be in?
inches
feet
MOA
MIL
IPHY

Re: 50 bmg bullet drop
Lave city barrett ammo 691 grn 2750 just within a general range give or take within a few feet if were to do it theoreticaly holding over

Re: 50 bmg bullet drop
theoretically....
BC=.625 G1(guess, not searching for a 691 bullet)
MV=2750fps
pressure=29.0 Hg. (guess for Fargo)
temp=85F
from a 100 yard zero, you need about 240-250 feet holdover*^
*don't try this at home, you are demonstrating a serious lack of understanding of how this all works
^ subsonic at 1550ish yards,

Re: 50 bmg bullet drop
a little under 3,000 inches or approx 126 MOA give or take depending on real world conditions

Re: 50 bmg bullet drop
In order to properly solve this equation we MUST have all the variables accounted for:
Elevation
Humidity
Temp
Up/Down angle
Barometric pressure
Muzzle velocity
Bullet BC
Barrel twist
Answer those question and we can give a realistic answer. Otherwise all we are doing is guessing.

Re: 50 bmg bullet drop
I understand all that but u realy only need that to get a accurate point of aim point of impact shot we just wanted a guess because people that dont knoe anything like to believe that the 50 is this lazer beam hold on and shoot to a mile just because it is big and bad. Just wanted a ballpark to give them an idea of what they dont know

Re: 50 bmg bullet drop
I was in a bar when I started this topic there was no external ballisics caise a shot wasnt being attempted just lookin for an on the average guess

No the BC on 690 APM2 is .675
The BC's on .50 BMG ammo has for years been VERY overestimated.

Re: 50 bmg bullet drop
I actually own a barrett m99 thats what started the conversation y is it that the 50bmg is so over dramatized the guy I was talkin to was like wow that big thing must only drop a few feet at a mile and I told him no it drops hundreds of feet and he wouldnt believe me he also thinks the bullet will rip someones arm off of it just even misses by an inch haha.
