Node at different barrel lenght

Hello, a friend myne had tested some Reload with a new powder.
This had find nodes at 38,7gn and 39,5gn.
My rifle and the rifle of this are identical apart for the barrel lenght, myne 28" and his 26".
Same bullets, same powder, same primers same case.
Have I some possibilities to find the nodes on my rifle near the friend nodes?
Thanks
To start with, two barrels of the same length, same material, same contour from the same company can still have chambers that are cut a little different even with the same reamer (reamers wear over time), which can produce different results. Even the bore can have a little different cut. Next, barrel lengths produces different velocities. . .the projectiles are in the bore for a different length of time with exactly the same cartridge load. Then there's "harmonics" where different barrel lengths vibrate differently, just like orchestral chimes. Different vibrations of the barrel means a different point of release when the projectile exits the muzzle.Hi, thanks for the reply, but what you explained is still too elaborate for my skills. Can you help me?
You might use your friends load as a starting point for your load development. You might get lucky and find a "node" pretty close to what's works for him.
