Assuming center shot and plunger, can spine selection become unimportant (forgetting about elevation here)?
For example, if bare shaft is perfect for #600, can the bow be re-tuned to bare shaft #300 arrows ?
I found a cache of stiff arrows that I'd like to play with (I usually shoot #600)...

Just from what I read on the Beiter plunger website; a plunger cannot overcome an incorrect spine. That being said; I have found that I can use arrows are close in spine such as 600s and 700s, with great arrow flight an accuracy.

First off it's .600. Called deflection because it's the amount an arrow bends with a 2 pound or 1.xx weight hangging in the center. Might be 1.96 I'd have to look it up.
When your moving the plunger:
Second it's easier to go weaker than stiffer.
When your moving the plunger:
If your going stiff once you get the arrow in line with the string and limbs you done.
When your moving the arrow out away from the window, you can go pretty far.
Could you shoot a .300 shaft out of a bow that's spined for .600? I'd guess you could but the arrow would have to be full length and the tip would probably weight twice what the rest of the arrow would weight. You'd end up with 600 grains or more and rainbow trejectory. So Not Really.
I have a bow that I shoot .620 and .390, so you can jump around but not as far as you want to jump.

The plunger can off set some spine issues but what you describe is probably too large to overcome.

fwiw I call 600 spine #600 to distinguish it from 600#, which is 60 pounds, and 60# which might be draw weight.
Thanks. What I actually have in mind is #600 (.600) with a bow that bareshafts perfectly with .700 (#700) full length with 100gr field points...

jk, I suggest looking at Stonebraker's Tuning for Tens.
Sections 1 & 2 will help you determine if your stiffer spined arrows are out of range of the plunger's tuning ability. As I understand Stonebraker's methods, they let one tune an arrow/plunger/bow, but only if the arrow is close enough in static spine to begin with.
All this does involve using a sight and perhaps you can use one temporarily to get you tuned. Good luck, and have patience with this tuning.

jk...it depends to some degree how the bow is set up now shooting the .700's. Depending on what you are looing to do, if you can move the .600's closer to the riser (toward center) and 1/8" or so you may very well be able to.
There's one sure way to find out and prove it to yourself.
