IOR of course. And one of those tier-one Harris Bipods in a Choate Ultimate Sniper .50 chassis.
Sirhr
Did someone say that there's 50 cal ammo for sale?
Did I miss this?
Is this still available?

I got your point. I asked a question poorly, clearly. I want to know how to determine ballistic coefficient on a supposedly custom made projectile since I have a number of them and want to become accurate with them. I have a dope sheet for them out to 1000 yards from a Barrett long distance course I took, but that is only valuable for the specific ranges and conditions I have logged. I can see that way I asked made it appear that I don’t know shit but have a high-end weapon. If it offends you that I have a certain gun but not the level of experience you feel I should have, my regrets. You got your jabs in, now how about some useful feedback, if you have any?
Don't lets these guys scare you off. They're just busting balls. But a 50 cal ? Son of a bitch that's s a lot of gun, have you considered 308 or 6.5 creedmore perhaps? What kind of classes did you take with a 50 ? You need to find a range with some distance, get a more suitable gun and buy Applied Ballistics by Brian Litz. Also take a basic precision rifle class. that 50 will pay for all of that. And roll with the punches your gonna take a few.
Yeah thats your zero dope.
If you have environmentals and elevation readings for 3 or 4 data points, then you have what you need to determine what you are asking.
There is actually a lot of good advice in here already. A 50 BMG as a new/introduction into long range shooting is not the best set up for you. I have a .270 & a 6.5CM that I can work a deal for you to get you out of that M107 if it helps you. It would come with ammo and instruction. Since I’m still in a holiday mood, I’ll trade you both of them.
I have a 308 and others. Took Barrett’s Long Range course with the 50. The ranges in my area are either too short or don’t allow 50bmg due to damage to the terminal berms. I’ve also taken long range courses with my 308. I appreciate your real effort to provide guidance. I’m good with the punches.
And on top of stupid questions, this clown poached a thread.
what a doosh move.

Okay so now we are getting to where you should have started lol.
If you have drop data to 1000 yards it should not be too difficult to come up with your BC.
Do you have rough idea of muzzle velocity? You can plug your know muzzle velocity and grain weight of your projectile and true your BC until it matches your known drop data in your calculator.
I only have rough MV, around 2800fps. An earlier reply indicated chronographs are not accurate...so not sure how to get more accurate there (don't have one anyway). I don't have grain weight, but will get that ASAP (no scale currently but will get one).
This is the info a ballistic calculator needs to give you a firing solution.
Bullet Info Needed:
1. bullet diameter.
2. bullet weight (in grains usually)
3. bullet length
4. bullet drag better known as ballistic coefficient BC (what you don't know about yours)
Rifle Info Needed:
1. Sight Height (Centerline of scope above centerline of barrel)
2. Zero Range (Usually 100yds)
3. Barrel Twist rate
4. Muzzle Velocity ft/s
Now if you have all of the above except BC you could find the BC for a similar weight bullet and plug that info into a ballistic calculator get some real world DOPE out to distance say 800-1000yds. Now you can kind of reverse into finding the correct BC for your bullet by.......
Example:
You shoot at 800 yds and the ballistic calculator calls for 7 MILS of elevation, but you actually needed 7.8 MILS of elevation the ballistic calculator (assuming all other data is correct) is either thinking your bullet is going faster than it is or your BC is greater than it is. You could adjust your input BC until the firing solution matches the actual elevation it took to be on target. The reverse of this is if you knew your BC, but not your MV you could adjust the input MV until it matched the actual elevation it took to be on target. This would be reversing into the correct MV.
Hope this makes sense I may have miscalculated your experience....LOL
This is a great place with a bunch of good guys, but you do have to get over the ballbusting at times!
You need to watch yourself with those kind of remarks. There are some really solid dudes in this thread alone that have done some pretty damn amazing things. You don’t have a clue who they are. So, if you read between the lines and stick around long enough to get to know some of them, these so called “want to be snipers” may just shed some light on how much of a bad ass they were before you came on here asking questions that quite frankly don’t belong in the bear pit, let alone piggybacked on a 9 month old thread...
Wow. You are slower than a subsonic.308
Thanks, that is helpful. I do understand what you are saying. I have everything but the MV, weight (which I will get shortly), and BC. I'll borrow a friend's chronograph to get the best MV I can, and think I can work with your feedback to get the BC. I appreciate it!
The problem is you didn't tell us how much you could bench or how long you've been working concrete

And just so you know the bear pit is not where you want to ask for actual information as this is what it will devolve into 100% of the time. Asking for into in the bear pit is guaranteed to get trolled in every way possible. The actual marksmanship forums will have this to a much lesser extent unless you earn it. Asking questions in the bear pit, in another persons 9 month old thread, with horribly worded questions and you got what you deserved lol.
There is a ton a knowledgeable guys on this site and great amounts of information to be learned. Also epic levels of trolling. Sorry you grabbed the mic at karaoke night and begged for it today.
Edit- take this on the chin, and move on, welcome to the hide.

Don't be distracting capitalists here. Especially, capitalists that attempt to define it here..
Bow kills... How many...? Need to know if we’re to answer any more questions!
I understand. I read the "read this first" info when I signed up, and unless I misread it, it said the Bear Pit is where I should ask questions if I wasn't sure where to. Lesson learned there! Also, as just noted above, I clearly was not concise enough. I am certain there are a lot of good, knowledgable folks here.

That is just Maser aka Marxist. He is not a real capitalist sniper like you attempted to describe. In other words, Maser can take 16 oz of hard tea to the sound of ding dong.
Go doosh up another forum. Thx.
damn. I was piggybacking this because he asked all the questions i’ve been scared to ask. Learned alot tonight.

Then you do understand capitalism as we know it and reeducated to us by the paid PX cadres.
What were you scared to ask? What happens when you are dense? Lol
honestly, you are asking questions above your pay grade.
unless you are wearing a silver american snipers org bracelet, you are not operator enough to know certain information.
lol, he lost me at “chronographs aren’t accurate for measuring MV”
Do you see the irony that you not only posted your first introductory post in a the wrong section but highjacked the one thread thanking people of that section for being ruthless entertaining savages. Not only that but a noob question about.50 BMG. Not exactly a beginner rifle. Its almost too ironic.
i know. And i know what chicken meant.
In context, it was just funny when he parroted it back.
