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...

Still knocking them out of the park! Beautiful!

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

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

I think your builder is confusing Bartlein with someone else.

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.

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...

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.

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

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

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...

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

LOL.

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