FYI I still would not advocate a tight neck for Fclass or TR, not really for safety, but the shear volume of brass preparation and the potential inability to borrow or shoot factory ammunition at a distant shoot should it be necessary.
We may have 2 disciplines colliding here on this topic, since in BR the tight neck issue is the norm and everyone is accustomed to it, vs the Fclass world where other issues dominate the choice of reamers.
I think that's exactly it. The fullbore world (TR/Palma and F-Class) is one of the most accurate forms of rifle shooting, and there's always good reason to look for a bit more exploitable accuracy. There is only one game out there with higher levels of accuracy and that is BR, so it is only natural to look to the BR world to see which of their tricks ad techniques can be imported to our game. Many can, but not every thing that BR shooters do ends up being useful in fullbore. Advanced techniques involve many subtle tradeoffs. Sometimes a given technique is overall beneficial in BR (and is therefore commonly done and it helps people win) but because of the tradeoffs involved it can be not helpful (or even worse off overall) in fullbore.
When trying to figure out what to do and what to not bother doing, it's useful to consider the relative importance of things. For example let's say you want to get decent accuracy out of a factory hunting rifle. Based on knowledge from fullbore and Benchrest, you know that bullet quality matters and so does brass quality. But before you worry about getting some Lapua brass for your hunting rifle you should realize that the accuracy effects of mediocre brass are *far* smaller than the accuracy effects of middling bullets (brass is at least ten times less important that bullet quality). So while it is *definitely* worthwhile trying out top quality bullets in your factory hunting rifle, quite honestly any old piece of junk brass will do the trick just as well as the very highest quality brass that you can get. It's not that the good brass isn't better, it's just that the improvement it gives you is so small that it will always and forever be complete lost in the inaccuracy "noise" from the other parts in the system that are less-than-perfect (e.g. bedding, barrel quality, action lockup squareness etc). Using good bullets is a big enough improvement to be worthwhile and it can give you improvements bigger than the "noise"; using good brass isn't.
If a good target rifle can shoot 1 MOA at 500 yards with crappy brass and your hunting rifle is shooting 3 MOA at 100 yards, using better brass is not going to help your hunting rifle. Whatever it's problems are, they are *much* bigger than any brass problem might be. Go find and fix something that will improve your accuracy by 1 MOA or 1.5 MOA (e.g. bullets barrel or bedding), don't waste your time with something that *might* be worth 0.1 MOA (quality brass) or 0.02 MOA (turned necks).
While fullbore rifles are more accurate than 99% of the rifles out there and they are built to very high standards, they still have "noise" of their own. While this noise is pretty small, it's still enough to overshadow and completely bury a whole bunch of really-tiny improvements that are out there, are real, and are being successfully used in the BR world.
Ha! (Colour me slow, I didn't get that the first time around....! ;-)
