    Just look at all that blue!

    I think this is one of those colors that look more green to those of us who don't subscribe to the traditional patriarchal chroma-normative identities....

    PWS new URX

    I think the titanium clamp based caliber changing system design is pretty slick, the venturi effect baffel to reduce gas backflow is a nice innovation and the moa accuracy sounds good too. The caliber change kit is $550, which is fair.

    Backfire 1 moa hoax video

    I work in a scientific discipline where we deal with these types of experiments all the time. There are basically three sources of error: Systematic error: Pencil thin barrels on hunting rifles heat up after a short string of shots and this opens up the dispersion of the group size. This is...

    Coup De Grace vs Nucleus or Origin

    Can someone explain why the conical breech on the CDG versus the flat breech on the nuc and Origin? I did enough reading to see how they are different but not the reason for the change from nuc.

    Any advantage to getting the 6.5 creedmoore version if one just wants it for hunting? Seems the .308 is about perfect.

    Springfield 2020 Waypoint?

    That's not necessarily correct. The main point of the carbon sleeve is that it is stiffer than steel. So a carbon sleeve on a thin fluted steel barrel is going to be stiffer than a steel barrel of the equivalent weight. As the steel barrel expands under heating, the tension between the...

    Springfield 2020 Waypoint?

    They are using BSF barrels: https://www.bsfbarrels.com/bolt-action-barrels It's a carbon sleeve around a fluted barrel. The carbon mainly provides mechanical stiffness.

    Tikka T3 Thread

    I'm not sure you really need any kind of bedding with modern materials and production techniques. Back in the day when you had wooden stocks and lower tolerance actions you needed an epoxy cast to match the shape of the inlet to the shape of the action and achieve a very rigid bedding area that...

    Excuse my ignorance but can someone summarize the reasons for the less than sterling reputation of Savage? Has there been lots of past reliability issues?

    Bartlein Steel Barrel vs Proof Research Carbon Fiber Barrel

    The different weave pattern may help the Proofs dissipate heat from the steel core better than the CA barrels. Heat transfers quickly down the length of carbon threads and slowly between layers of a CF cloth. On the CA barrels, the carbon threads are aligned lengthwise with the barrel and heat...
