6 Dasher Velocity Increase after 325 rds

[Texas Solo]

Now that I have 325rds on my Dasher, my fps has increased by 47fps from original break in/load development. It went front 2852 to 2898. Measured 10 shots.
Is this about the norm?

What changes have you recorded in ambient temperature and how is the extra speed affecting the target ?

Temps are about 25* higher now.
Groups are the same, but POI is about .500" lower at 100yds.

I watched mine jump 15 fps in 15 degrees in less than one hour. I’m sure it sped up a bit from break in also, i don’t have that in front of me but only the target matters.

Completely normal

30-60fps is normal and will likely be seen in the first 30-60 rounds max (independent of temperature)
