    Here's another one.

    Ballistics Calculator - Hornady Manufacturing, Inc

    Using the information from the 7N1 sniper round that's available in what Moose provided- 2812 max fps and a 152 grain bullet, plug in a BC of .45 (from a 155 gr. SMK) and you get a bullet drop of 45.5" at 500 from a 200 yard zero. Pretty close to dead on with the data on the chart... clearly, the 7N1 bullets are pretty impressive in terms of their BC.

    Alternately, plug in a BC of .200 from a 150 gr. round nose (lousy ballistics)- and at the same muzzle velocity of 2812 fps, it would have a drop of 81.7" at the same 500 yards. Nearly double the drop (actually it's probably a bit less as the BC actually gets better with this bullet as it loses velocity)- illustrating how important a bullet's ballistic design is to flat shooting.

    I was going to say 60 to 80 inches just on what I have experienced. If you are shooting at a man sized target, aim about the length of the mans hight over his head if you adjust the sights you can be pretty close. On my M 91 Finn they are pretty close out to about 700m. The problem is that with my Mark I Eyeball it is beyond my performance envelope (wasnt that a nice way of saying that)

    Bullet drop at 1000 yards is about 391in or 32 feet, at that distance everything is a factor wind, bullet, gravity, Tempature all that Fun stuff

    OK. So now I have a new word(s) added to my vocabulary: 7N1 and 7N14. This is supposed to be super accurate ammo for my MN. Really good info and I must note that it is no longer available and cost like the dickens when it is found. Now the good news burried in this info was that "Chezk" ammo called "Silver Tip" is the equal to 7N1. I have some Seller Bellot stuff with a soft lead tip and I have some primi Partisan stuff of that same description. What is "silver" tip, is it hunting ammo and what does it cost and where can I get it. Whew!

    Thanks,


    John

    most of the "silver tip" you come across is just going to be regular steel core surplus ammo. if you want accurate ammo, you need to load your own.

    I had Czech Silvertip. But it was in the green lacquered cases, which I don't think the 7N stuff is.

    That is more than likely correct. Most of those programs are pretty good if you put in accurate information and not just guessing at some of the variables.

    if you are zeroed at 100 yards , thats about right for 200 yards.

    It's all about the BC of the bullet you're shooting as shown in my example. A high BC bullet (HPBT) for this round will be about a .5, the round-nose will be much less. Smaller bullets have lower BC's, but you can push them faster...

    The variables are velocity, BC, and bullet weight. Without knowing the BC of some of the surplus ammunition it's more or less an educated guess at best.
