[ARCHIVED THREAD] - Zero question (Page 1 of 2)
Posted: 3/1/2012 8:36:10 AM EDT
| If you have to shoot at 25m, 50m, 75m 100m, 200m & 300m, but can only zero at one of these distances, which would you choose? |

Quoted:
Interesting. Thanks for the responses all. I would go for 300 too, but in practice I only have regular access to 200 so use that. No-one went for 25 then.......that's a relief Incidentally it's not for 5.56mm, but .308 165grn, BC 0.348, at @2700-2800fps. 25

You don't need a 300m range to zero for 300m Here's some Data for the L1A1 for example
100 meters Iron set at: 300m .............. Correct Zero Position in Relation to Point Of Aim (POA) in Millimeters: .............. 125mm Above SUIT set at: 300m .............. Correct Zero Position in Relation to Point Of Aim (POA) in Millimeters: .............. 150mm Above, 25mm Right IWS set at: 200m .............. Correct Zero Position in Relation to Point Of Aim (POA) in Millimeters: .............. 113mm Above, 25mm Right 25 meters Iron set at: 300m .............. Correct Zero Position in Relation to Point Of Aim (POA) in Millimeters: .............. 13mm Above SUIT set at: 300m .............. Correct Zero Position in Relation to Point Of Aim (POA) in Millimeters: .............. 25mm Right IWS set at: 200m .............. Correct Zero Position in Relation to Point Of Aim (POA) Here is a diagram for the AR explaining why this works. 
After you have your Zero best practice is then to conduct application of fire practice to confirm points of aim for different fire positions and fill out shooters record cards/log sadly in the UK forces the application of fire stage gets seldom done due to time constraints |

This is the same problem we have .. |

Quoted: Well lets not hope there are a lot more of those L1A1/FAL rifles out there or your shit out of luck with a 25m zero for 460m engagement, unless your at 465m You're also shit out of luck @ 465m if all you've got is a 9mm pistol and a G36c, and your opponent has an L1A1/FAL and knows how to use it...  |

Well I plan to be at @160,000m so I should be ok  I believe there were some training opportunities for L1A1 and FAL owners in Libya fairly recently....... |

This thread reinforces my view that it is sometimes better NOT to know something
In this case, I wish I didn't know that the armed plod out on the streets 'protecting and serving' me probably have inadequately zeroed firearms and insufficient training time to learn their points of aim for likely engagement distances

The hundred yard snipers? Not much aiming off required

Heaven forbid any of these boys in blue ever come up against anyone that actually knows what they're doing

I have only met two officers who have completed a police sniper course. The first hung way back during the stalk excercise and worked out the pattern of the observers. He sprinted a few metres at a time and threw himself flat. Repeated this until within range and passed the stalking stage !! The second was giving it large about just becoming a fully qualified sniper when he was asked about firing from a roof. "So, when you are firing down to street level at a steep angle, say from a four story roof, would you have to aim high or low ?". He did not have an idea. "So, you are a sniper in a police force serving in the capital city. The chances of firing at or from a steep angle are quite high. And you dont know how it affects your bullet impact ?" He blustered that it was complicated and us mere non snipers would not understand.

Would depend, what range did he zero at?

 Ever wonder why most armies zero for 300m? It enables you to shoot center of mass all the way out to 300m so no remembering hold overs !
If you for whatever reason choose 200m POI is approximately 10" lower At 300m which oddly enough is pretty near to what it was high at 200m for a 300m zero funny old thing that! |
