Just torque the barrels on if it gives you wandering zero or fliers you can't figure out. Otherwise you're fine.

I've posted my explanation for 75-100 before but here it is again:

I tested snapping them on hand tight up through "way too much".

I could not get any zero shift or impact shift from day to day or when I whacked the barrel off something above 50 ftlbs with a 308 case head and 65 on a Win Mag. However, since lots of people don't have a torque wrench and "good enough" is a wild range depending on the person (farmers like shit TIIIIIIGHT) then our spec that I've published for years has been 75 for 223/308 and 100 for mags. This gives a specific value for folks and the consistency isn't an issue.

Ted says 100 because he asked me and I told him what my data was... so he used it.
Aaron from Zermatt asked me what I recommended when they were making up the insert cards that come with all their receivers and I told them too. So they used it.

The AI system isn't a point load. It uses a cutout in the tenon thread that the screw closes up the effective pitch diameter and drives preload into the joint by closing down the thread in the receiver to create a normal force on the ramp which in turn creates tensile load in the joint. Point loads on thread suck... which brings me to:

The Curtis system? No, it causes problems sometimes and we decline warranty of zero shift and groups when that system is used. Every single time that we've had an issue with a barrel and the set screws were installed it was fixed by removing those set screws and torquing the barrel in place. MPA ran into that years ago and quietly stopped recommending the use of the system even though their branded actions as the time from Curtis still had the features in the receiver.

Back in 2009 or so it was relative commonplace on this forum for someone to talk about having issues with groups and wandering zero or fliers in a freshly assembled Rem 700 build. One of the first things that was brought up was "check that your front action screw isn't too long and touching the bolt. Check that the front scope rail screw isn't too long and touching the top of the barrel threads."

In 2017 or so the powers that be in the market decided another quick change system was needed and since the systems on the market that created preload into the joint were already patented the set screw setup was adopted. This was about the time that the WTO lug was flashing into popularity and the "I can change barrels at the range" idea was all the rage.

Well shoot, I just ordered a Terminus QC.

aha i think i see what you're saying, and it makes sense. the actual distance has to be used as it affects time in the air and thus windage, where the horiz effective distance would be used for drops. so you'd need to input actual distance and angle and the program should calc/know the horiz distance. i was just trying to understand tbe issue... not helpful in answering you though...

Im in CA so no suppressor. A suppressor would likely fix the short stroking though bc its right on the edge

Yeah thats sucks yall can’t have suppressors there. And I agree a suppressor would definitely fix the issues you are seeing with the gassing issues.

It's two years later, but did we ever get an answer to what this flute count was?
(and contour)

7 flute, 7in twist, left hand.

Close enough, call it whatever you want. It's your wildcat.

To my knowledge I cut the first barrels for AI's in the following calibers:

6 Dasher, 6 BR, 6BRA in that order. The Dasher (2016ish) in fact, was taken to a match where several members of Team AI NA were in attendance and told the owner "That won't work, it won't feed". The owner then proceeded to win the match. Within 6 months he was wearing a Team AI NA shirt and I got several requests for mag kits and one of the Team members ordered a barrel from me.

That same owner also ordered a 450 Bushmaster from me and used it to great effect in a straight-wall regs area of his home state to clobber a bunch of deer.

I've also done a 458 Win Mag AI barrel for a guy in Ohio and a a 338-300 PRC Ackley for the same guy because he didn't want to deal with the Lapua for some reason.

I have a bunch of 223s, and multiple 22LR, and 6 ARC and 300 HAMR uppers.

Just one upper? That’s crazy talk.

Just one of each? Even crazier!

@Rubicon Precision you can demonstrate this for yourself in your loading room. Have any split die rings from forster? Not the Redding ones Josh described above.

Screw the die into a traditional press(rock chucker for example). Make sure the die ring clamp screw is loose. Now screw the die ring down to the press so it touches(no torque). In this state, you should be able to grab the die and unscrew it, the flanks are touching but almost zero load.

Now tighten the clamp screw on the die ring. The shrinking pitch diameter pulls a tensile load against the press. You will not be able to remove the die by hand any more, at least not easily.

Now you’re making it click!

I’ll admit I was wrong!

I bought two about 3 weeks ago - an 1836 US Property flintlock and an 1842 US Property percussion. Haven't had a chance to shoot either one, yet (and probably won't anyway).

this may not be the "oh no, how can she do something like that" everyone thinks it could or should be.

Perfect approach, wish I thought of that. You're right on the money.

Higher end Vector is a pretty decent Chinese scope. The closest it got to German glass would be if some of the scopes are shipped by air and flew over Germany.

That’s not a screw, that’s the locking tabs in the receiver. The arrow shows the direction the are loaded.

Oem Turkish gun, oem Chinese optic. Losing industries to China starts with Americans buying chicom oem stuff.

The irony is you're probably posting this on a Chinese made computer (at least the major components), which is fed internet from a Chinese made modem/router. Not to mention pretty much everyones cell phones, TVs, etc.

Also, to my knowledge, there are zero RDS that are 100% American made. Most are US assembled, but not all components come from the US.
