I believe this is a bit of the misleading statement. Every major match in my recent memory has been won by a sponsored shooter. Many of these sponsors are gunsmiths and having their shooter use a prefit barrel goes contrary to the purpose of sponsorship which is drum up more gunsmithing...
Hard to diagnose without being there but what kind of rifle is it? There is the possibility the chamber was headspaced to minimum dimension and the sizing die is not sizing down enough.
Size is the same but might be too hard to reliably ignite, depending on the mass of the FP and mainspring weight. Before I loaded a bunch, I would load 50 and try them.
The relief for the ejection port is just cosmetic. While you are having the lug pocket opened up you might also check to make sure the barrel channel has enough room for the barrel nut, otherwise that's another issue. Another thing is make sure the notch for the bolt handle clears. The TL3...
The TL3 has a thicker integral recoil lug than the M700 washer type recoil lug. The FRONT of the recoil lug pocket in the stock and possibly the sides of the pocket need to be relieved to accept the TL3 lug. You do NOT want to relieve the back of the pocket because then the action screws will...
Since the scope you are intending to mount has enough elevation travel to comfortably get a 100yd Zero with a 20MOA cant, there's no reason not to have it. Better to have it and not need it, than need/want it and not have it. If the scope had a very limited amount of elevation then it could be...
Something doesn't sound right. The rifle is supposed to come with a 20MOA base and you only have about 20MOA of elevation on your scope. You shouldn't need to add another 20MOA to that. I would take everything (scope, rings, base) a part and start over.
Clean and degrease EVERYTHING...
If you're loading on a single stage press you could take a few thousandths off the caseholder (cheapest part). Considering you're using a 650, make sure you've taken up ALL the slop in the press and die toolhead, before you start modding anything. Since you're trimmer indexes off the shoulder...
Cases can grow during the sizing operation if the die does not make contact with the shoulder of the case. Think of this; the case is forced into the die, the sides of the case are sized down the only unsupported area of the case is up. If the case makes contact with shoulder of the die then...
Received mine and installed. The lightest I could get the T3 trigger with the FACTORY spring was about 20-22 ounces (1.25 lbs). With the new spring it's down to 14-15 ounces, with no slam fires. Two Thumbs Up.
A whole lot of what you wrote is suspect. Not saying it's not accurate but that doesn't mean it's true. The design of the AI action is such the tolerances are kept within a given specific range. I'm certain Robert Gradous knows the tolerance and chambers his barrels accordingly.

Having had about ten USO scopes with four currently in possession this is my perspective. A few years back, when there were fewer competitors in the precision tactical market, a USO scope was highly sought after. However with the entrance of Vortex, Kahles and others the consumer has many more...
