[QUOTE="bigngreen, post: 1600635, member: 13632"] There are three main things I look for in a good candidate for a Lapua class chamberings. Larger than .700 bolt diameter, I want a flat or coned bolt nose, and larger than 1.062 tenon. Titanium stretches much more than steel and even in smaller cals we see bolt lift sooner than a steel and even in steel actions you'll feel bolt lift sooner in some than others bases on material and heat treat. I would be very suspect of a 1.350 diameter Ti action for a Lapua class case simple based on how elastic Ti is, and putting larger threads than 1.063 in a 1.350 body that's Ti and it's going to be a compromise. I see issues regularly with RUM class cases setting back lugs and tenon movement in a Rem size action, a Lapua just magnifies all the issues. I see a couple makes of high end factory rifle come in frequently for poor extraction of Lapua cases because they just can't handle the full capability of the Lapua case so I polish the chamber and do the best I can so they can at least function at a lower level but it's obvious that just because it doesn't blow up does not mean it works good!!!
