Hijacked by pointless ELR noise..... Don't know why you would say that? Someone tries to help you and you seem to take offence. Why ask the question if you don't want an open discussion on the technical side of the problem. I started the thread, others starting talking about something unrelated - c...

Alan, please explain the difference between BC and wind deflection?

Can't say much about them...they still under development. I have some coming in 185 grain for 30 cal and 168 in 7mm. There are others as well, but they are the ones I am interested in for now for F/TR and F Open.

This is why I want to test my projectiles - so I have hard data to go on - not subjective heresay.

As long as we only shoot to 1000y in competition, it is not important what happens after that.

Maybe we can call the BC difference - "the shedding of V differential". The difference of TV is really the only thing that matters in this discussion. If two very different projectile designs get to the target at the same time, in the same conditions, at the same MV: then they will have the same BC....

Norm, I understand how this works, I have been trying to include everyone in the thread so they can understand it. There is no need to know the V at the target, this can be worked out by use of the known example BC. The TOF will give the TV - they are linked together. I will put money on the fact th...

Alan, I did think of this also - actual drop figures. The major problem is atmospheric conditions. Using time as a constant take that out of the equation, although the two things will theoretically give the same outcome. By testing alongside a very well know set of BC data (the Berger 180 VLD), the ...

Using the data from the known projectile, and then reverse engineering the MV or V loss, a cross comparison should be pretty straight forward. Using this method, I computed my 260 wildcat elevtion within 0.5MOA at 1000y. In other words, the terminal velocity (TV) is also constant, and does not need ...

Checking your own projectile BC

For some time, I have been thinking about how to record my own BC data for projectiles, now that I have access to some custom projectiles. The BC is only estimated, so a much better idea of how these things travel needs to be known. From what I have gathered, two things need to be known accurately: ...

Pretty sure they can't be used on a typical private FAL. What on earth would the purpose be for having one?

If it were raised: on a statistical basis it is better to give everyone firearms and remove their drivers license. There are thousands killed and maimed for life in vehicles, but you dont hear the same outrage.

It is PC shit that is wasting valuable oxygen.

Probably. I will stick to people that live and shoot internationally in the 21st century.
