Nitro,

When I build mine (Mauser 98, 300 Wby Mag full thread, forend fixed to barrel) it took some time to settle in and had to be adjusted however it no longer has any issues.

I am intending to replace the 300 Wby barrel with a integral featured barrel but more due to the fact that I didn't cut the barrel thread and am not entirely happy with the barrel/receiver fit.

It needs me to add the second barrel (375 Wby Mag)and build it a case.

I don't have any "thread wear/headspace" issues..........even after multiple takedowns and 600-700 shots. I can't imagine how many times you'd have to takedown and re-assemble one of these to affect a properly cut thread.

Next is a takedown Winchester 92 in 45 long Colt using the original (but full thread) Winchester format.

Takedowns/switch barrels are a great idea, especially for travelling.

I've carried mine many times in a duffel bag (taken down with barrel and forend up one end of a soft bag and buttstock/action/scope up the other and guncase folded in half)on airlines (checked baggage of course) without being required to use a separate gun case..........but times may have changed since.

Takedowns are like .375 H&H Magnums..........ever boy should own one at least once.
