enfield: sighting in a scope help please

[brit84]

Hi,
Im using a weaver scope on my enfields with one of those no-drill/tap mounts. I cant get on target with the scope and bottom out on the adjustment and still be nowhere close.

Could anyone suggest anything i could try! I would assume lifting up the rear of the scope a little...but how? the mount isnt adjustable up or down.

thanks!!

You have bottomed out the elevation adjustment, and the rifle is still shooting high?
You willl need to shim the bottom of the front ring, to raise the front of the scope. If you raise the rear of the scope, the rifle will shoot even higher.
Bring the scope back to center before you start shimming.
Bore sighting and them shooting at close range (25y) at a large target can help getting a zero.

Once you have the old girl hitting the b i g piece of paper, it will be time for something a little finer.

Try the old British Army method of setting up your scope. Takes 2 rounds only and it WORKS.

Best way to do this is to use a SQUARE aiming-point, preferably something about 3 inches square, and do your shooting from 100 yards. What you do is lay the vertical crosshair down the left side of your square, then put the horizontal cross-hair along the bottom of your square. Squeeze the trigger carefully.

There should be a bullet somewhere on the target. Doesn't matter where the thing is; you're on paper.

Now comes the sneaky part. First, remove your scope caps. THEN take exactly the same aiming-point as you used to fire your shot.

Sandbag the rifle FIRMLY into position and take every care you possibly can to NOT move it. Check your sighting; your sight-picture should be the same as when you fired.

NOW you adjust the cross-hairs of your scope, moving the BULLET-HOLE so that it moves to the intersection point of the cross-hairs.

You now have the rifle and the scope looking at the same point.

Load and fire a second round. The bullets, in theory, should enter the same hole. They won't, of course, but if you have done everything right, they will be very close. Now all you have to do is adjust your vertical zero for the range at which you want the rifle dialed in.

Old as the hills, and works every time. Saves a TON of ammo, too.

Most important point: have fun.

When i look through the barrel with the bolt removed and line it up on the paper, the crosshairs are too high and wont move down enough. This is why I thought the rear ring would need a shim.

What should i use for shimming? just some pieces of rubber?

If you put the crosshairs on the aiming mark, where is the bore pointing?
Whatever you use for shimming should not compress. Shimstock, aluminum strips from popcans, etc.

The way I boresight my enfields is to setup an 8 inch bull at 100 yards. I carefully place the rifle on a benchrest without the bolt in and aim the bore by eye at the target, making sure that the bull is in the centre of the bore. Without touching the rifle, look through the bore to verify that the bull is roughly in the centre, then look through the scope and see if you are pointed close. Adjust the scope until it is pointed at the centre of the bull. You'll have to go back and forth a couple of times to make sure the bore and scope are pointing at the same place. When everything looks good, take a shot and you should be with 8 to 12 inches of point of aim. Works everytime for me, to the surprise of others I show.

Using this method you'll see an interesting optical effect as well. The bore works as an aperture and gives you massive amount of depth of field, you can see the bull crisply and it will be slightly maginified too.

Oh, and for the no drill tap mounts, make sure that the wedge is fully tightened down if you are shooting a No.4 with the S&K type mount, or the rail might be cocked a bit upwards.

Thats how i was sighting, i have shimmed the rear ring a little and and it looks much better now. The rail is slightly tilted upwards, i cant get it down any more unless i grind it a bit.
