NOT!
At least not mine
I did a test, 2 X 10-round groups fired in as close as possible to identical conditions several weeks apart. Both started with a clean, cold bore & were fired timed fire to heat the barrel.
The result?
A single 4" round 100 yd group at 100 yds with even dispersal of the rounds within the circle.
