rem 700 titanium action

found a 300 ultra built on a rem titanium action. nice gun and i am thinking about buying it. however, i have heard from several individuals that titanium flexes a little more and can therefore effect the accuracy of the weapon. is this true and should i worry about it or not??

Re: rem 700 titanium action

I know it costs a pretty more than steel, but cant say with any certainty that it flexes more. I was actually under the impression that it was stiffer. (again I may well be wrong.) This is probably best answered by one of the smiths on this site. If none of them chime in, I have really enjoyed talking with Kevin at Mountour County Rifles. Maybe give him a ring and run it past him?

Re: rem 700 titanium action

shawn carlock is building one of his custom rifle packages on this action. He would be a good one to talk to about it. If he is building custom rifles on this action I doubt there is much of an issue with its accuracy, but it would be worth a chat with him about it.

Re: rem 700 titanium action

I don't know the Ti alloy used however steel has a modulas of elasticity of 29,000,000 psi
and Titanium has a ME of roughly 16,000,000 psi

So yea, its very much less Stiff (modulas of elasticity) given the same physical geometry.

Re: rem 700 titanium action

Acually titanium is stiffer. The lower PSI number is stating that is has less flexibility and will facture sooner. Kinda like bending a tube of glass or plastic, glass is stiffer but will fracture or break with less pressure. Steel is more ductile or flexible. When is the last time someone tried to bend a reciever in half, these are not the type of forces being generated. Titanium is very tough and resists change and movement from atmoshere and heat very well. The drawback to titanium is cost at about $35.00 lbs or more and the machinability is very low, driving manufacturing cost WAY up. Titanuim is the way to go if you can afford it, in my opinion.

Re: rem 700 titanium action

Incorrect. Please don't confuse Modulas of Elasticity with Yield Strength.

They both use PSI as units. Neither has a direct connection with the toughness (impact or fatigue generated)

ME or just E is basically the slope of the stress strain curve BEFORE the elastic limit is reached. Meaning that slope is the "stiffness" of the material. A lower number indicates more dimensional (elastic) deflection with a given load and geometry than its counterpart. Steel is twice as stiff as Titanium... You will notice titanium or aluminum revolvers use steel in strategic places to prevent such deflection from causing problems. Again, were talking about stiffness Before ductile yielding occurs.

I'm not saying this receiver will perform worse or better, chances are there are Steel Inclusions or geometric Changes over a original receiver to account for the changes in properties.

You are covering quite a few material properties that are Not always related to each other. Toughness, Yield Strength, Work Hardening, Modulas of Elasticity, and finally Coefficient of Thermal expansion.
