I have a Remington 742 in .30-06 that is drilled and tapped for a scope mount. I have no idea if this was factory or if a previous owner did it. Any idea what kind of mount I need?

I'm not sure about the Model 742, but I have a 7400 in .270 with factory-tapped holes for a scope base. I also have a 740 in .308 with a scope base on it, but it had that when I bought it, so I don't know if tapped holes were factory standard or not. That 7400 shoots as a tight a group as any sporter-grade bolt action rifle will. Not so much for the 740, but even it is plenty good enough for most any hunting need within 200 yards. Should take a standard mount base, am sure Weaver offers one.

742s were factory drilled and tapped. I was into them for awhile
back in 60s. Weaver makes a one piece base for them, also a
pivot base that allows you to swing scope over on hinges to use
iron sights. I still have several of the mounts in my scope stuff.
The 760 pump uses same hardware. I think it will also fit all the
newer versions of both guns, 742 & 760.
 
The phantom base mark on the receiver top looks like a Redfield Jr. rotary dovetail base (#47170). Leupold also made/makes a one piece base (#49992). It's an excellent mounting system and you should have no trouble finding one online or at a large gunshow.

My whole hunting crew had 742s & 760s back in 60s, all had the
Weaver pivots. No problems with them, back then Weaver was
the popular brand. Redfield & Leupold are both better than Weaver. If I was going to buy them today I would buy Leupold.
If for no other reason, made in USA. Weaver ain't in Texas no
more.
 
Drm50 and Litenlarry both use a mount that is great for the woods and if you are stuck looking at a low sun which is the reason my Dad put the Weaver pivot mount on his 1953 or 54 Win M-70 in 270. The sun was setting behind a giant buck but it could not be seen in the scope. Did Dad ever kill a deer with iron sights? Nope but he had it.

The mount is approaching 60 years old, it is on the old M-70. I own it. Dad was a good shot, he learned with a scoped 06 in North Africa during WW II when the game shot back.

The mount is not opened and closed much, I was a little leary of it but Dad had shot targets and deer at 500 plus yards in front of witness' with me being one of them.

I put a Leupold 3x9 on the rifle and have hunted with it for 10 years. I've used it in 4 or 5 different states and the zero has never changed.

I bagged 2 does on my farm last year at over 400 yards, the same the year before and multiple other times. I don't fear nor worry about the mount. Use a rest, check the wind and elevation, squeeze and it's steak and jerky time.

I also have a Weaver tip off mount for a Commercial Mauser that I've held onto for years waiting for the right rifle.

I prefer the old Redfield or Leupold mounts for all my other guns due to most don't come with iron sights and have a taller cheek piece, but The weaver stays on the old Winchester until my Grandsons get it. You never know some deer season the sun may be in my eyes or an asteroid smacks the Leupold and I can just keep right on hunting.

I have been unable to shoot deer several times when the rain was so heavy the scope could not be used. If I would have had a tip off on it would have been a godsend.

There are some mounts that are TALL and have see thru bases. I tried them, you have to hold different and peek under the scope and most are aluminum, my brother and others have taken a fall during a hunt or dropped the gun and the TALL mount bent or broke and they had not checked zero on the iron sights. My brothers gun was an old 740. I put a set of the tall ones on a 742 I had and changed them out for tip off mounts. Just remembered I had tip off mounts on a Win M-100 308 carbine, my first deer rifle, I killed with both the scope and iron sights, i Think dawn and dusk did not work well thru older cheaper scopes.

On my 740 and 7400 I have the one-piece Weaver mount base, and just use the standard low Weaver rings. They work fine for me. The more expensive rings like Leupold are fine, but expensive, and I don't think they provide any advantage over Weaver rings, unless maybe you are using them on some heavy magnum rifle. I don't believe in magnum rifles much either. I suppose the swing-over pivot mounts are OK if you think you will ever need to use your iron sights, but will be considerably more expensive. I wouldn't consider using the see-through mounts, as they are not very ergonomic. I tried those once, and didn't like the feel of them - your head must be held more erect. Might be OK if you can practice some to get used to them. I think I have two pairs stuck away somewhere, don't particularly care if I never find them.
 
I just barreled my 760 {same bases as the 742} in 260. I used the bases made by Warne. They are solid steel, two piece and not expensive as steel bases go. I cannot tell them apart from Leupold Mark 4 bases side by side and the Mark 4's are like $160.00. Brownell's has them as do other online shooting suppliers. I also don't recommend "see thru" mounts...they were a fad in their day. They seemed to make sense, so everyone had them. Scopes are much better today and you really want your scope mounted as close to the centerline of the bore as possible.

Edit: One thing to always check on the 742 is the barrel nut. Take off the forend and double check the barrel nut for tightness. If it comes loose even a little bit the gun cannot be zeroed and will not shoot a group at all.

There used to be a so-called "Accuracy Block" which could be purchased and installed on the 740 and 742. Maybe it is still available somewhere. I made my own out of brass for my 740. Easy if you have access to a lathe. Even with it in place, grouping with the 740 is merely OK, not great. The 7400 used a different type of attachment which eliminated the problem.
 
DW, is right 742/760 series are not target rifles, they are 200yd
meat guns. Fine for in the woods deer hunting. I went accuracy
bloc route, no difference. We had to drop down to 2350fps with
180 gr Rn to get 2" at 100 yes. (3006) decided we might as well
use 30/30s. We did shoot a lot of deer with these rifles, most
under 100yds.
 
I think I may have a Leupold 742 scope base in the gun closet somewhere. New in box. If you want it, I will sell it to you cheap, provided I can find it.

Remington barrels are spotty...you might get one that shoots great and then again maybe not. I would say the accuracy enhancement you tried didn't work because it couldn't help a bad barrel. My 270 760 could not do better than a 4 inch group at 75 yards. When I scoped the bore it was so guntched up inside it's a wonder it shot that good. Nephew had a Sendero in 264 win mag, same thing...it just would not group. He was lucky, that barrels problem was in the last inch and I just cut it off and did a recrown. It now shoots 3/4" groups at 100.
I have seen many 760/7600 rifles shoot very good right from the factory. The one I have is now a 260 with a Shilen barrel. I don't know if I would call it a target rifle but.....
