I'd like to see the difference between the two (standard vs magnum) extractors. I suspect the only difference is the radius, it shouldn't create a different gap between the extractor and the breech. To your point though, I don't think the extractor could cause a light primer strike because the...

I don't think it's the extractor, but to check for rubbing put some sharpe ink on the face of the extractor and repeat. If it's rubbing the breech, you'll see some ink removed.

This. Another way of checking (and determining the extent of the extractor interference) is to remove barreled action, unscrew barrel a couple of revolutions, then with the bolt closed slowly screw in the barrel. You'll feel it bottom out against the extractor - or if the interference is...

Threaded 5/16-24. Terminus knob is male threaded, most aftermarket are female threaded. Just connect using a 5/16-24 set screw. Google bolt knobs, dozens to choose from.

The Lone Peak Fuzion is a smooth action, but I completely disagree that the Zeus (or any Terminus) is "prone to binding", there are none smoother. Get in touch with Joel, he'll take a look at it and if there is a problem he'll take care of it. I've built dozens of rifles with Terminus...

The pull weight of the trigger has no relation to the bolt lift weight. Bolt lift weight is a function of the cocking piece moving up the the cocking ramp which is retracting the firing pin assembly/compressing the firing pin spring. Although not clear on what you mean by the firing pin...

It looks like you plan on using a flat head screw by countersinking the screw recess. KRG designed their chassis to adjust magazine fit by movement of the forend and trigger guard a small amount each to allow fine tuning of magazine fit. Since the countersunk screw on the trigger guard will no...

It's a pretty easy fix with a mill. Just need to inlet the aluminum backbone and trigger guard screw as shown on my KRG Bravo. Also a little inletting just in front of the rear action screw. I also milled down the trigger guard front set screw. The Dremel "inletting" on the right side below...

I doubt they use a die to thread their barrels. There's no way to accurately cut the threads concentric with the bore since a die registers from the OD of the barrel shank. You might be seeing crystal remnants from the exterior phosphate treatment that wick into the threads.

Gotta say I've never heard of a reamer being "too sharp". If the reamer is chattering, it usually means the bushing is undersized. It could be a mis-cut reamer where one cutting edge is cutting more than the others, or the primary cutting angle is too shallow. As an outlier, I'm sure you...

Completely agree with everything . . . except 3-phase. A Variable Frequency Drive will convert single phase to 3 phase. Inexpensive, easy to set up and most will allow programming such as spin up/down time.

Measure from the shoulder of the muzzle threading to the front of the muzzle. The Area419 adapter can only take about .650" of threads before it bottoms out. Your muzzle looks like it has an exceptionally long thread gutter (unthreaded portion between the threads and the shoulder). Edit - I...

I'll leave the semantics to professional machinists, but I'd say the tool is a surface grinder, the process in this instance is cylindrical grinding. So if it helps, you can say it's cylindrical grinding using a surface grinder. Surface isn't limited to flat.

It's a BEMA Maschinen FSM 260, a German machine. The screen shots were from Stefen Gotteswinter's YouTube channel. He was grinding a bevel on the spindle of a tube micrometer to be used specifically for case neck thickness measurements. Many micrometers have a carbide tipped spindle that...

Actually, he's right. It's how precision gage pins are made. Part is held in a rotating fixture then turned as grinder wheel spins. I think he was being factious - it'd be ridiculous way to sleeve a bolt and to bring this back to topic, there's nothing wrong with the CDG's bolt to body...

This edge - right? Since it doesn't contact anything you can take a file to it and soften the edge if it bothers you.

The Bergers are 10% below advertised speed and that is more than I would expect. If the Hornady match ammo is shooting only 65 fps below advertised on a relatively fresh barrel (2845 fps is only 2.2% below 2910 fps), I don't think it's the barrel. If you're not getting high pressure signs, SD...

That's an odd "step" between the OD of the muzzle and the OD of the barrel. It does appear to match the OD of the brake. Frankly, I wouldn't worry about it. That radius doesn't look sharp and it serves no shouldering purpose so in the even you did ding it, it would only be cosmetic.

@PRSDietitian I've got a Kreiger 7mm blank in 7T. PM me if you're interested.
