Titanium Rail Bases, Pros and Cons

I am considering one of these Titanium bases that Murphy Percision makes for a new build I am doing.

MurphyPrecision.com - Scope Bases, Rings, and Assorted Shooting Accessories.

I think the strenght of the material will be good, I can get it with #8 screws and it will cut some weight. Plus it will look great on my new Defiance Action.

Anyone here tried one or had one in their hands to examine? I haven't called yet but I do not see a recoil lug. That would be nice to have.

Is anyone else making Titanium Rails?

What you all think?

Jeff

Re: Titanium Rail Bases, Pros and Cons

wow, Nobody has one of these?

You mean I might be the first kid on the block with one?

I was hoping for some input.

Thanks!

Jeff

Re: Titanium Rail Bases, Pros and Cons

It will be stronger, it will still weigh twice as much as aluminum.

Myself, I can think of many things I would buy before I'd spend $200 on a scope base.

Re: Titanium Rail Bases, Pros and Cons

Broz--coupla thing I wonder about...

Like you say, would be good to have a recoil lug.

Also, doesn't appear to be an extended rail design such as Glen Seekins of Seekins Precision offers for 1/2 the cost. Maybe Glen could bead blast a rail for you and not anodize it so it would have the look you seem to want? I don't know. Might still save some $ and have a lighter setup with extended rail and lug.

I've heard from a Boeing eng. friend of mine that when they used titanium in planes and had to do drilling/machining the metal would have to be kept cool, or it would lose some of it's adventageous properties. Not sure if that is going on here, but it it is, it would certainly make the machining process more difficult and costly.

I've done a bit of research into titanium vs. 7000 series Aluminum (have to be very aware of the various alloys offered in each and their respective negs/pos/strengths, etc.) and have found that for what I was looking for, it was awfully hard to beat the 7000 series Aluminum for weight vs. strength vs. cost ratio--you could even take the cost out of the equation and it was still hard to beat 7000 series Al. For something that is machined to a specific dimension (vs. engineered to specific strength, for example) as Geargrinder said, Al will be lighter and 7000 series Al already beats out some steel alloys in strength.

For instance, titanium brakes may be lighter that SS brakes, but they won't be as light as 7000 series Al brakes...but I'm guessing smiths don't use Al for that due to it's low melting point.

I'll stop blathering now...

Re: Titanium Rail Bases, Pros and Cons

Good points.. I am after strength. The more cheap bases I am around, the more I am seeing the value of a good base is money well spent. I have had my last go with a cheap flexy base. On a bolt rifle, I see the base as a reinforcing bridge that strengthens the area of the action that is going to hold the scope true to the barrel. Not a place I care to cut cost.

I have used many titanium parts in racing. From valves to Spring retainers holding 900 lb springs to Bell housings transfering over 3000 HP. Titanium is very tough stuff. We used a lot of it and it was amazingly strong, and very light for the strength you get.

May be just in my head, but I have a fear of an aluminum base not having the strength in the bottom of the screw holes to do as good as job as steel. I have seen aluminum pull and bend in these type of areas.

But I have not used one of Seekins bases. Does Seekins keep these on the shelf?

Re: Titanium Rail Bases, Pros and Cons

I think that 7000 series Al (certainly some alloys within this series) may be a different animal that what most of us typically deal with, namely softer, weaker 6000 series Al. In some cases 7071-T6 has a yield strength higher than some titanium alloys, as I recall. And, screw hole bottoms yielding shouldn't be as great of an issue in a rail with a lug...unless I'm interpreting what you mean by 'yielding' incorrectly. The lug should take any load that occurs such that damage to screw hole bottoms shouldn't occur anyway. Am I making sense?

Call Glen directly. He often answers the phone. I wouldn't bother emailing and haven't had a great deal of luck with leaving phone messages. Just try him every once in a while or so throughout a workday when you think about it. I usually get through within a day or two doing this.

Re: Titanium Rail Bases, Pros and Cons

It would seem to me that the weak link to going with titanium beyond maybe machining and cost is the SS screws....Like saying the bridge is built out of titanium but the bolts holding it together are SS...just my 2 cents...I agree with others and would go with good quality aluminum base if you want to save weight. Personally I like the SS ones but, they do weigh a little more.
