    Adding weights to McMillan or a manners?

    I’m not making any more of these, nor selling them, but I did make a few steel ARCA rails for some shop rifles that were tapered at the rear so they sit flat against the Manners T4 stock, and some steel “spacers” that fit between the stock and the cheek piece for weight and ballast. It worked...

    SENTINEL Hunters in 6.5PRC just dropped.

    Still knocking them out of the park! Beautiful!

    Is this normal?

    So what’s your expert opinion on the OP’s pics?

    Is this normal?

    It’s amazing how well rifles shot before cheap Chinese borescopes were in everyone’s hands….

    300 NMI questions

    I think your builder is confusing Bartlein with someone else.

    Prefit barrels, and how the barrels are indicated during manufacture

    I doubt any do that. You’d be crashing tools if you tried to rapid a bushing that is >.0002” smaller than the bore, if the bore was out more than that.

    Prefit barrels, and how the barrels are indicated during manufacture

    If you find a builder to tell you how they hold a barrel, the maximum total indicator reading they will accept pre-machining, and where that reading is taken, how do you plan on verifying it once you get the barrel? I know how I’m doing it. I know how some others are doing it. My method works...

    Barrel vise bushing?

    Meaning, torque wrenches aren't meant for breaking fasteners free. You can damage them using them as such. Use a breaker bar instead to remove the barrel.

    Barrel vise bushing?

    If your torque wrench actually measures CW AND CCW, stop using it to remove things.

    I’d be looking at a straight .284 Win.

    White cerokote to reflect the sun

    Ever notice how heat sinks are always painted white? Me neither. They are either left as cast/machined or painted/coated/anodized black. (Sometimes reds/blues because looking cool matters…) A barrel is a heat sink, albeit, not a very good one. It is transferring heat generated inside to the...

    White cerokote to reflect the sun

    It is when you’re talking about radiant heat and pressure from a star some 90 million miles away.

    White cerokote to reflect the sun

    Hang on, we’re thinking heat from the sun affects barrel life?…

    White cerokote to reflect the sun

    I’d bet it has far more to do with tradition than thermal qualities.

    White cerokote to reflect the sun

    If sun is the only heat source, white would lessen it. But I’m pretty sure the automotive world has found that black is better for shedding heat from within, or I could completely be making that up, who knows.

    Proof Prefit 6.5 Barrel

    If a new 6.5 CM barrel isn’t shooting under an inch with factory Hornady Match ammo immediately, there’s something wrong in the system. Be it the barrel or something else, like Ern mentioned. More rounds is just more rounds wasted.

    Are these threads OK?

    That needs to be cut off and redone.

    Rebarelling an HS Precision Pro Series action

    I have a HTR Pro-Series 2000 from about 2001. It’s been forgotten in the back of the safe unused for probably 15 years. For grins, and now maybe I’ll rebarrel it and offload it, I popped off the barrel. Rather, I put the barrel in my vise, slid in the action wrench and as I was about to put...
