Remington M700 scope alignment issues

Well the new (to me) SPS 30-06 is accurate but only on the paper at the extreme of lateral scope adjustment.

M700 30-06.
Talley bases (6x48)
Talley screwlock 1" rings
Zeiss V series 3-9x42.

Scope lateral adjustment range is 54inches. Divide by 2 = 26 inches. Rifle is on at extreme edge of rightward adjustment. Therefore assuming the issue is in the base hole spacing (and I will be checking another set of bases, rings and scope) it would appear I have a 26moa lateral issue.

From the research I have carried out options are

Windage bases - no thanks
Insert bases - no thanks
Blank talley bases drilled to account for the hole position - problem not solved at source
Move to 8x40 and ensure the new holes are positioned to take maximum benefit of the size difference.

Seems like I should have enough to play with? MOA is approx. 0.001" at the base end? 26moa = 0.026". 6x48 = 0.135", 8x40 = 0.160" which theoretically gives me 0.025" either end.

Any issues with my thinking?

You are on the right track.

Just verify the issue is the screw hole alignment. Could be a poorly machined barrel, or receiver.

I like to strip it to the receiver, put the screws in, and place a straight edge against one side of the screws. A misaligned screw shows up quickly this way. All the screws should touch the straight edge, and everything should be parallel to the bore.

Consider the burris rings with inserts.


Mike

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.

Try turning one of the rings 180 degrees.
The error may not be in the base screw holes at all.

The Burris signature rings with the inserts work very well. You can buy different corrective insert that provide up to 20 inches of correction with a single ring insert. Other inserts provide 5 or 10 inches of correction. I used them to correct a severe lateral offset on my Gradfather's Mod 99. Guy who drilled and tapped it must have been looking in a mirror at a fun house. It required a 20 inch corrective insert in the front and rear rings to bring the rifle on target. Yes, it was over 40 inches off laterally. Shoots great now.

Smith's view is also to turn the rings.

I have a vaguely OCD character - addressing the issue via inserts or windage mounts isnt for me.

IF it is not a scope, rings, base issue what about contacting Remington?

You won't see the difference with the Burris Signature rings and this should help your OCD.

They really are great and absolutely will not scratch up your scope.

God Bless, Louis

How far off is the scopes dead center alignment to the tip of the bore?

Or has the smith measured this?

Quick update,

Turning the rings sorted the issue. The base also happens to be fractionally undersize so is going back (two rings won't tighten on it fully)
