Yes...the other thing you can do is hang a plumb bob from a rafter in the shop about 10 ft out in front of the scope. Use fluorsent twine and you can double check against that...

Never under estimate the internet community's ability to reply to your post with their personal rant about their tangentially related, single occurrence issue.




What I have learned on AR, since 2001:
1. The proper answer to: Where is the best place in town to get a steak dinner? is…You should go to Mel's Diner and get the fried chicken.
2. Big game animals can tell the difference between .015 of an inch in diameter, 15 grains of bullet weight, and 150 fps.
3. There is a difference in the performance of two identical projectiles launched at the same velocity if they came from different cartridges.
4. While a double rifle is the perfect DGR, every 375HH bolt gun needs to be modified to carry at least 5 down.
5. While a floor plate and detachable box magazine both use a mechanical latch, only the floor plate latch is reliable. Disregard the fact that every modern military rifle uses a detachable box magazine.
6. The Remington 700 is unreliable regardless of the fact it is the basis of the USMC M40 sniper rifle for 40+ years with no changes to the receiver or extractor and is the choice of more military and law enforcement sniper units than any other rifle.
7. PF actions are not suitable for a DGR and it is irrelevant that the M1, M14, M16, & AK47 which were designed for hunting men that can shoot back are all PF actions.
8. 95 deg F in Africa is different than 95 deg F in TX or CA and that is why you must worry about ammunition temperature in Africa (even though most safaris take place in winter) but not in TX or in CA.
9. The size of a ding in a gun's finish doesn't matter, what matters is whether it’s a safe ding or not.
10. 1 in a row is a trend, 2 in a row is statistically significant, and 3 in a row is an irrefutable fact.
11. Never buy a WSM or RCM cartridge for a safari rifle or your go to rifle in the USA because if they lose your ammo you can't find replacement ammo but don't worry 280 Rem, 338-06, 35 Whelen, and all Weatherby cartridges abound in Africa and back country stores.
12. A well hit animal can run 75 yds. in the open and suddenly drop with no initial blood trail, but the one I shot from 200 yds. away that ran 10 yds. and disappeared into a thicket and was not found was lost because the bullet penciled thru. I am 100% certain of this even though I have no physical evidence.
13. A 300 Win Mag is a 500 yard elk cartridge but a 308 Win is not a 300 yard elk cartridge even though the same bullet is travelling at the same velocity at those respective distances.

Lay a 6" steel rule across the top flat of the scope base and rotate the horizontal cross hair until it is parallel to that.

I can't visualize this- more detail, perhaps?

I've done a lot of damage to myself over the years- slow on the uptake. bewildered

responses appreciated, thanks.

Place the rifle in a rest. Look at the scope base. You will likely see a flat surface on the top of the base where you can lay a little 6" steel rule across it. Slightly loosen the ring screws. Step back and look through your scope and find the horizontal cross hair. Now while eyeballing the cross hair and the steel rule, turn the scope until the cross hair and rule are parallel with each other. Tighten the rings and recheck the horizontal alignment. If you don't have a 6" steel rule, use a popsicle stick or anything that is small and straight, that will lay across the top of the scope base to give you a reference.

I have used his method:


Place scoped rifle in a Black and Decker workmate or bench vice, suitably supported / padded with towels.

Using a spirit level, ensure the rifle is level in the axis parallel and and right angle to the bore.


Next,

Obtain a small spirit level and place / balance it ontop of the top 'scope turret.

Rotate / 'twiddle' with the scope in rings until the spirit level bubble is centred in the spirit level 'eye'.

Hopefully, provided your rifle receiver and scope bases / mounts are "true", you should be suficiently on that you will not notice any significant cant.

I have tried this method on two rifles: one with square bridges and Talley clamp rings and another rifle with 'normal' Tally rings and bases. It worked ok for me.

Good luck. Remember to remove spouse / partner, children and pets out of the way when trying this. I have found mounting a scope with Talley clamp mounts a real test of patience!

Gawd, everyone has their own pet method or 2.

An easy way I have found is to take a 6 inch piece of coat hanger and bend a 2" leg on it so you get an "L". Wrap electrical tape over the short leg until it fits snug into the muzzle.

Now you can put this in the muzzle, look through the scope and line it up with the vertical crosshair and the croshairs will then be centered over the bore, even if the mounts are off center.

Since then, I made a plastic plate with a V notch that centers on the barrel and a slit cut in it so you line up the slit to the crosshair. I like that better than sticking things into the muzzle but they both work the same.

I do most of scope mounting at my dad's house and since his living room has wood paneling in it. Such being the case, I've always put the rifle in a rest and aligned the vertical crosshair to a line in the paneling. Sometimes when I'm done I'll check the horizontal with his reticle leveler, but its seldom off.

All you need to mount a scope is something to hold the rifle still and something else that's straight that you can align your reticle to. Whatever you use, the process is all pretty much the same.
