With AMAXs I can shoot 1-1.5 MOA, with Ball Ammo that doubles up to at least 3 MOA.Ī 38 ft drop seems awful extreme at 1000 yards NO SHIT!. PS: IMHO, if you want to shoot long range accurately, don't waste your time with Ball Ammo. May be worth a phone call to Cabelas or Magtech to see what is up? Makes me wonder how those numbers could be that far off the norm? Standard numbers for "comparable" Ball Ammo: The max I have ever seen anyone run is around 3,000 and that is considered to be hot. Muzzle Velocity - 2,952 is a screaming velocity, HSM AMAXs run around 2,680, and Barrett Ball is around 2,750.

It did shoot a sub 1 MOA group from 100 yds though? I havnt had a chance to get to a bigger range yet so I was messing around with the software trying to get an idea of what i would be dealing with.īallistic Coefficient - BC of 0.364 seems to be way low, standard BC for Ball Ammo should be in the 0.650-0.670 range. Does this mean this ammo is crap for long range? I have access to it at my local shop and at a very good price. I got the numbers from Cabelas Magtech/CBC 50BMGĪ 38 ft drop seems awful extreme at 1000 yards. Hi, I am getting a bullet drop of around 38 feet (465 inches) in the MBall and Sierra software using the following data: Magtech/CBC 656 gr, BC. I have the following Weights and Ballistic Coefficients for Surplus Military Bullets, do they seem to be correct / what everyone is using? I would assume it is somewhere between 2,600-2,800 fps, but that is a big velocity range to be working with at 1,000 yards, a 50 fps variation is good for 10"-12" at that distance. All else fails, I will get on the phone Monday morning to Summit, but I am shooting this weekend, so it would be great if I could a number before Monday. Did Barrett offer M33 with 2 different weight bullets, or did you just use the default Military Ball weight? I have some older Barrett that I pitched the boxes for because they were all torn up, and if they offered 2 different weights, then I am going to have to try and figure out which weight they are.ĭoes anyone have a velocity number for the Summit 690 grain Ball Ammo? There is no ballistic info on the ammo box, and the Summit website is down for improvements. I checked the Barrett website and they list the weight of their M33 as 661 grains. ZAK, you posted the weight of the M33 as 647 grains. Since they pertain directly to ballistics / trajectory I figured it would make sense to post them here, versus just starting another topic. Not to doubt you but are you sure that BC is correct? It seems awfully high to me. Give me the bullet, MV, and environmental conditions and I can get more specific data. I do not know so I can not claim or disclaim that this number is correct. If you are doubting the the BC for the AMAX 750 gr, then rest assure that I too looked it up a week ago and 1.05 is correct.
