Is New Load Development Required After Swapping Chassis?

[theDuck]

For those of you who have swapped out chassis on a bolt action rifle, did you need to develop a new accuracy load for the rifle afterwards?
Thanks

I would think not, if the barrel is free floated. If it were me, I would check some of the developed rounds just to be sure.

The load shouldn't change but the harmonics of different chassis may change the grouping (accuracy) torquing the chassis bolts to a different setting may restore or improve your grouping.
Start with the same torque setting as the previous chassis if the group opens run a test and change the torque by 5lbs.
50 - 65 lbs is the range most common.

The chassis manufacturer usually provides a torque setting.

Try it and find out.

Shoot a bunch of 5x5's while swapping between chassis's. See what the results are. See if the results are repeatable.

The POI may have shifter slightly after the new chassis was installed and torqued. make sure there are no pressure points and the action bolts are torqued to spec, you should not have to develop a new load but may have to adjust your scope to get back to your previous POI

Depends on how badly the fitment between action and chassis is between the 2 options.

Thanks for the responses.

I went from a Savage Stealth chassis, ( MDT ) to a MDT XRS and used the same load without problems.
