Improved Angle Cosine Indicator

[Jeff In TX]

W.

We can debate this topic for weeks on end. Who can do this and who can't do that. Long-range shooting disciplines come down to individual needs and requirements. For myself I'm quite competent and comfortable shooting at targets to a 1000 yards and I'm pretty **** good at it. Am I the best…..absolutely not, but I'm well above average!

I'm always looking for ways to improve myself. I've learned to work from the KISS method and for me it works just fine. I don't have to have all the latest widget and gadgets attached to my rifle to call myself a good shooter. The **** thing weighs in at almost 16 pounds as it is.

That's all BS and nonsense. I've seen a few shooters with factory rifles with a tasco or simmons scope shoot and hold there own with some of the best of them.

Not having a ACI or this or that doesn't always make the shooter. That's like me telling the guy on the firing range next to him, that my $3500.00 TBA rifle (including glass) will out shoot any factory rifle or custom rifle on the line that cost less than $1500.00 dollars and is topped with a tasco scope. That's a load of crap

However I have shot with some of the best shooters in the country and a cold bore shot at 700 to a 1000 yards is not always a given as you make it out to be. Not saying it can't be done because it can, but there are lots of variables involved at that distance.

As for Bruce Robinson, he passed away a few weeks back. I've tried to call his wife Lou Ann to express my condolences. I heard about his passing a couple of weeks afterwards. I'm don't have any ideas of the cause of death except that he passed away. Bruce was a great contributor to our sport and his Mil-Dot master is one of the greatest tools ever invented for the long-range and tactical shooter.

I've stuck a fork in myself on this one and I'm considered done!

Well in contrast to those who shoot long ranges all the time, there are those who don't.
We don't shoot foulers, or sighters. We don't shoot off a bench, or rest. With a radio playing and a Martini(shaken -not stirred) in a cup holder. Some of us shoot in different states than we live, and actually carry our rifles hunting. Shots range from 50yds to whatever we can get. Up/down hill shooting may be needed. And the prey isn't hanging, or clanking when we finally hit it to impress the gallery. Many shooters have to wait months between shots under real world conditions.
Facing this adversity, gadgets such as an ACI, laser ranging, PDA and any other FIELD device, can make a huge difference in hit probability.
I for one, appreciate toys, fore I couldn't hit crap with a Mildot & folklore. Not in the real world.

Jeff in Texas: As you probably know, accuracy begins with the stick; ie. stock, bedding, reciever, BARREL, quality scope etc... That is the foundation from which all knowledgable shooters/hunters operate from. So, I geuss there are two kinds of shooter's; the average Joe, and then the guys in the know. The guys in the know can and do make 700 yard cold bore shots without a problem. The average Joe doesn't shoot beyond 200 yards Ever.

For a guy that is concerned about extreme accuracy, I am somewhat surprised and taken back by the fact that you do not have an ACI mounted onto your rifle. Perhaps your method works for you, however it is not as accurate nor as solid nor anywhere near as dependable. That kind of takes me back about you. Now, you mentioned the "Late" Bruce Robinson, whats up with Bruce?? What's happened???

The SEALS use the ACI, the ARMY uses the ACI, the British special forces use it, I wonder why ????? might I add, all real world operators under extreme conditions.

A hunt is hunt, man or foe, any tool that can and will aid in the ability to put a round first shot at any angle should be seriously cosidered. enough said.

Froggy,

I have many friends who are former US Army and USMC snipers. I've shot, practiced and competed against many of them. Since the US army is moving to the AN/PVS-10 day-night optic, I'd love to know where they mount that ACI.

You see I'm not saying that those branches of the arm services don't use ACI, but they are not standard issue. That means in theory they can't not be attached to the USMC M40A1 or A5 rifle. Other than spray paint and a improvised taped cheek piece, that's about the only modification a US marine corp sniper can make to his service weapon. Wow, there some of the best tactical shooters in the world. They've been trained to use simple tools for shooting at angles. Sometimes it's as simple as a $1.00 protractor with a string and fishing weight attached.

I sure there are a lot of branches of the service that use the ACI and again, it's probably a great tool. At $89.00 it's just a bit pricy for me and I've been trained using other methods for calculating and shooting angles.

You all act as though if you don't have this tool, you can't shoot at angles. That's just BS! Tactical shooters from all walks of life, have done just done just fine over the last 100 years without that ACI.

If it works for you that's fantastic. My self and countless others have done just fine without one. I'm sure if I tried it, I'd probably like it, but not at $89.00!

Jeff,
Having trouble emailing you. Did you receive my email sent yesterday?

Froggy, W,

If by 'British Special Forces' you mean Royal Marines that's fine (although properly they're 'specialist' forces (ie amphibious infantry) -not Special Forces). 'SF' in UK parlance means SAS/SBS or an NI specific unit. UK SF don't use the L96 shown in your website pictures (!); they have been issued the L118A1 (the AW)for some time.

That said, I do think it looks like a clever gadget and wish you success with it

Brown Dog,

Sorry, yes I recieved it, I just hadn't gotten a chance to play with it yet. My wife and I went to watch my oldest son play college baseball in their final fall tournament this weekend and got in late last night.

I started to look it over this morning! My first thoughts are WOW, you've been quite busy. Looks as though you found a project and to sink your teeth into and also jumped in with both feet.

It looks as though, but I'm not sure you are using a cross between a modified and massaged G1 drag model and Dr. Pesja ballistic model. Very different and it looks very promising, I like it!

I'll be out west on business this week and I'll try to spend some time while I'm in the hotel working with it and provide you some feedback.

Thnaks for all the work.

Jeff: Badger manufactures a Military specific mount for the ACI. It is designed to work with both day and night scopes and is currently in wide use. If you have the time, and it isn't too much of an inconvienience for for you, visit the Badger Ordnance site, there you will find the mount. Currently the U.S. Army, Navy, Air Force and Marine Corp purchase the ACI and have been since competition in Afghanistan commenced. Since you know so much about what is being issued to our Military, perhaps you can tell me who is utilizing the Black Hills 77 Grain White Box ammunition? Everyone, or just the SOF guys....

Instead of multiplying the cosine to the distance to target, he multiplies it to his moa holds from his data card. Interesting… And he swears by it.

This produces the same number, does it not?

% X Yardage
% X MOA "come up"
