If you don't know exactly where the gun is shooting or are just winging it, you are simply wasting ammo. Unfortunately every time you change loads you will have to alter the rear sight settings and this should be done off a bench rest to minimize variables. Now that you know where the gun is shooting you can learn what sight picture produces hits on whatever target you are shooting at.Īlso any load that is slower than your standard load will result in a positive elevation increase and if you shoot your cast boolit loads off a bench and record the settings for future use you will only have to do this once. Or you can start at 50 yards and work out to 200 if you can't see that well.(like me) You must still verify at 200 yards whether you can see that far or not.Īt that point you are good to go with that load. (I make a tool to do this predictably)Īll this needs to be done off a bench rest at 200 yards. 008 = 1 MOA with this sight radius, changes to the blade result in 2" at 100 yards Once you get the right front blade installed so that you are dead on at 200 yards then you jack the Front Sight Blade side to side until your windage is right. There are 9 of them.(available on Ebay) they are calibrated in. Getting the elevation to be right, may require the use of different heights of Front Sight Blades. Changes in muzzle velocity which affect that trajectory can be calculated and compensated for predictably. A given bullet, fired at a specific velocity, will have the same trajectory no matter what gun it is fired from. All of this can be calculated using a ballistic computer or tables in some loading manuals. They spent a lot of time and money perfecting these systems and they all are based on a given trajectory of a bullet loaded to a specific Velocity. If you duplicate that load your sights will perform correctly. If you are using some form of Factory 150 gr ammo, when the elevation and windage are zeroed at 200 yards with the sight set at 200 yards, the come ups for the different ranges will follow the ladder sight perfectly, and the Ghost ring should be dead on at 300 yards, if you choose to use it.Īll military battle rifles with iron sights have sights that are regulated to a standard Military Ball Load. Not having to think about whether or not the sight is set correctly for a given distance makes doing the same thing with the sight picture and trigger pull much easier to execute. Then you can practice putting the front sight on the target and pulling the trigger. Once you understand how they work and have a standard load to regulate the gun to, it all falls into place.
#PATTERN 14 ENFIELD DISC HOW TO#
Jeep: there are many sources here for information on how to use these sights properly. I find it hard sometimes to get good accuracy with open sights. They still appear (not cheaply unfortunately) on eBay. But Parker-Hale and Alfred J Parker made accessory micrometer windage slide to clip onto the No.4 version, and accept screw-in discs.
The No4 Lee-Enfield rear sight is less well protected than the P13, P14 and M1917 versions, between the receiver "ears". It was a reaction to the Boer War of 1899, and nobody has ever fought another war in which the infantry rifle was the dominant weapon.
Whether anybody in the world has ever needed a better long-range cartridge than the. Remington Magnum, and could have been overcome sooner if some idiot hadn't started a war, which made a change of cartridge undesirable. 276 cartridge, but they have been long since overcome with rifles like the 7mm. There were problems of flash, noise, metallic fouling and erosion with its large. I think that is true, and the military aperture sight originates with the P13 trials rifle. The US caught up in a hurry though with the design of the M1 Garand rear sight. The British were certainly ahead of the rest of the world as far as rifle sights went in the first 40 years or so of the 20th Century with their early adoption of aperture sights placed on the receiver bridge. The US 1917 derivative of the P14 also used the same sight, but calibrated for the US 30/06 ball round of 1906. Good they are, particularly the Mk I sight.įrom what I can tell, I do believe though that the British Pattern 13 (circa 1912) and the Pattern 14 (circa 1914) rifles led the way with a good aperture sight.
