A thread below got my wheels turning and it brought me to a question. When mounting a heavy scope to a heavy recoiling rifle, should you use a steel rail and rings rather than aluminum or is 7075-T6 strong enough?

Has anyone actually seen a 7075-T6 rail or rings deform or fail due to recoil?

The weak link will still be the mount screws. I prefer aluminum but I have steel too.

One of the best features of the late, lamented Fieldcrafts is the five-hole 8-40 mounting scheme. I think Kimber uses the big ones now as well, maybe others.

Seekins aluminum if I'm trying to save weight, Nightforce steel if it don't matter.

And both have the built it recoil lug that butts up to the front of the action, taking the stress forces off the screws.

Doesn’t much matter, IME. Get one with a recoil lug, though.

Seekins is exactly what I was looking at. They're backordered, so I sent an email asking for a lead-time, hopefully it won't be too long.

The recoil lug should eliminate the need to upgrade to 8x40 screws; should it not?

or Titanium, just to be different : - )

the FN-H A3-G Special Police Rifle came with a titanium rail to make the FBI weight spec, and I have that rail on a few rifles. Not sure any real world benefit to me, but I like them

Aluminum has less stress cycles than steel--that's why the aircraft industry keeps close track of the lifespan of various aircraft parts. Aluminum is also softer and "peens" or "coins" easier. I have had that happen to me with aluminum weaver style mounts.

Guys who shoot a lot with heavy scopes seem to be the ones with failures of rings or mounts. Back when scopes were heavy most of us used steel mounts and rings, when scopes became lighter, aluminum mounts/rings became the norm. Now that we have gone full circle there is an argument for steel.

I've looked at a titanium rail from Murphy Precision. I'd have to look at it again to determine if it has a recoil lug.

Picatinny through bolts are wider than Weaver, so match the slots to the type of rings. Upgrading the mounting screws to 8-40 is worthwhile too.

I agree with this but many of the newer picatinny rails are hard anodized and it makes a big difference, if it's not anodized I'll go steel

That is true, good point.

Does anyone know of a maker of a steel Picatinny rail for a Mauser 98 with an integral recoil lug like the Seekins and Nightforce?

So when you install a rail, do most of you bed it, or just screw it on to recommended torque and call it good?

I'm familiar with Badger Ordnance rails and how/where their recoil lug butts-up against the receiver, but forgive my ignorance, as I've never used a Seekins rail. How does their recoil lug work on the receiver? Explain the slot/cutout ahead of the ejection-port cutout. I'm assuming the recoil lug drops down into the ejection port to interface with the receiver......

That’s correct.

Don’t know what model rifle you’re buying for, but I just this morning ordered an Area 419 rail for my R700
