Re: Cosine Indicator


An emotional post. When you've sipped on a decaf and taken some deep breaths...

I'm in the British Army. The ACI is not.

I hope that is easy enough to understand [img]/ubbthreads/images/graemlins/smile.gif[/img].

(What you must have seen on television is the result of private purchase by individuals of a neat gadget.)

By all means sound off again. I have ended on this subject [img]/ubbthreads/images/graemlins/grin.gif[/img]

Re: Cosine Indicator

Listen Guys, yes I get a little upset when people question integrity, Brown Dog I'm not doudting that you are in the British Army thats a big outfit and a fine one at that.

GoodGrouper as I stated protractors and string will work, Sorta $20 vs $100 is a big jump.

In a nut shell and this is EOS for me( End Of Story ) If you want something that works, is rugged and reliable and is used by special forces snipers all over the world, Including England, because it's the best piece of equiptment for the job out there, then please give Sniper tools your business.

I'm not doubting that the slope doper will work, snipers in the old days used a protractor and a piece of string, If you want to spend $20 for a Slope Doper then by all means go ahead, I would not trust my Trophy to it over the ACI but again thats my opinion.

Sorry if I offended anyone, My goal in this thread was two fold, to protect my friends Integrity and to also endorse for him what I profesionaly feel, is the best piece of gear for the job it was designed to do out there.

I'll think I'll have that cup of decaff and a deep breath now Ol'e Chap, Tally ho, What, What, thanks, Carry on, [img]/ubbthreads/images/graemlins/grin.gif[/img]

Froggy OUT.

Re: Cosine Indicator

This is directed toward all.

Gotta step in here.

We've apparently ceased to post anything constructive on the subject of this thread.

Time to get back on topic and civil.

Maybe some editing is also in order...

I waited.. no response so I performed the edits... 20 Jan 2005

Re: Cosine Indicator

I would agree with Dave, lets stick with the constructive forum that has set this site apart from the masses, instead of turning it into a hash slinging secession. Multiple points of view are the basis of a good forum, but if someone has a point of view that differs from your own don't take it personel. It is simply a point of view.

Re: Cosine Indicator

I have been using the Exbal program for several years. It has worked great out to 1000 yards with my 308 win & 338 Lapua Magnum, however I have been routinely shooting my 338LM past 1K and the accuracy of my Exbal program drops off pretty dramatically past 1K. For example Exbal says I need 36.6 MOA at 1300 yards, but it takes me 40 MOA, and at 1600 yards Exbal says 51.1MOA but it takes 57.5 MOA. I am looking for a more accurate ballistics program so allow me to get first round hits out to 1600 yards.

The Exbal allows me to get on steel in one or two rounds at 1600 yards but I want to be better than that.

Re: Cosine Indicator

I'm not interested in reading through any slanging matches. But i will tell you this. Drown Dog is correct when he says that the ACI is not on Gerneral Issue to the British Army, He aught to know. and i also know for a fact, that although many British Army sniper and special forces teams are using the ACI, it is bought either by the individual or on what is know on local pruchase.
It should be on General Issue, that is a fact, as should a set of badger rings for the S&B PMII as the AI rings are inferior.
Having spent 10 Years in the British Army i can tell you as a fact, kit like the ACI tends to get bought by individuals for thier own personal use, it takes years for the slow wheels of MOD procurement to get moving. which is why in 1982 in the Falklands we where still using the same combat boot as we had in Korea, Some Spec forces and Marines, if allowed by Unit Standing Orders, wore civilian hiking boots as an alternative. It took until the mid/ late 1990's (15 years later)untill we finaly got a waterproof combat boot. Same story with a decent rucksack and load carrying webbing, we were issued 58 pattern webbing, it was totaly unsuitable for the equipment we had to carry, we all went and bought, out of our own money, either from the PRI shop in camp, civie out door shops or from specialist companies and actual system that would work, berghaus bergen ruck sack, and either chest webbing or stuff from specialist manufacturers, its the same story with clothing, we were issued out of date items, we went an bought our own decent kit, like norwegen roll kneck shirts,( as late as 1992 i was issued the same damn shirts my father was issued in 1947) Arktis SAS smocks, we all had a trip to a US base to visit the PX and bought Matterhorn boots. the list is endless, and it is the same now. The guys are buying thier own kit. Special forces have more , lets call it buying power, to localy purchase gadgets and items that are well thought out and actualy work. An infantry company sniper does not , unless he has a darn good boss who is into shooting and on par with evolving technology that is willing and able to make troop funds pay for such items.
Its not much better for the US forces, Ask the guys over on Adopt a Sniper if the US snipers have the ACI on general issue, by all accounts logisticicians cant even manage to muster up scopes and mounts, slings and bipods for many sniper rifles, bino's and range finders, never mind a handy gadget like the ACI.
I will say it again, the ACI should be on issue to every Sniper within NATO, it is a darn good bit of kit, one of those things that you think, darn wish i'd thought of that. I like it so much i have 2.
The simple question as to wether the ACI is on issue to the British Military is: Whats the NSN ( NATO Stock Number) ?
Occupying the British Zone.
