Node at different barrel lenght

[RTTY]

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

The simple, yet frustrating answer:

- Maybe. Maybe not.

Barrels are individuals, so the guarantee that his load will be equally good in your barrel isn't there. However, certain cartridge/bullet/powder combinations seem to do well in many barrels.

You'll have to shoot it to see.

So the solution is the usual one...
Try loads in 0.2gn increments near the best SD and ES rounds?

I’d be more concerned over length than charge based on my experience

Can you explain me better?

In my experience the cartridge length impacts group size more than charge. The old adage is that powder changes vertical and length changes horizontal

My approach for load finding are to start 2 or 2,5gn below the max load data for the combos.
After finding a good load make some seathing adjustments.
