just like the title says! for those barrels that have short life i've been thinking about getting 3-5 at a time to save time on waiting. doing a "switch lug" or "mrad" types will make it easier for pre-testing/load development. any other insight is appreciated!
do tuners "cheat" barrel harmonics or is there another way to duplicate previous barrel

With use of a tuner, you can initially develop purely for a powder node, then use the tuner to reach a barrel node on top of the powder node.
If your other barrels are from same steel lot, and finished the same, your powder node should hold, and you'll be close with prior tuner setting.
It IS cheating.

i haven't used or needed a "tuner" as of yet. thinking of possibilities ahead and hopefully barrels of the same lot is why. would a custom reamer or a specific reamer to the cartridge hold a more truer possibility of obtaining a more equal barrel to barrel process?

Holding a reamer, and having all barrels cut with this same reamer, will ensure that your chamber matches across multiple barrels.
I think it's best to have the machinist finish all barrels together, so that head spacing/breech clearance/threading/crowning will match as well.
The last time I did this was with 3 barrels. It worked so well that nothing about the brass, die settings, or load results changed as I burnt through them.

That is cool to hear. Something useful for long term with one chambering. Thank you.

I just want to express my admiration for anyone who would buy 5 barrels at one time, knowing he/she is going to shoot through all of them (4000-20000 rounds depending on cartridge and use). You're my new hero!
Tuners don't work. They appear to work with small sample sizes because of the stochastic nature of shooting, but don't actually influence precision over many rounds. If you have a good smith chamber multiple barrels at the same time they'll all shoot pretty much the same.
