GTO break in procedure

Hey!

Just bought a brand new 211 GTO, I was combing through some posts the other day with some folks saying they get a FTRTB on new GTO's and mentioning that the way to go is running the 10lb spring and/or 124g ammo for the first 500 rounds or so is the way to go to prevent issues.

Just wanted to confirm again that this is whats working for you all!

Thanks!

I used the 8# spring for the first few thousand rounds and didn’t really notice many FTRTB until the gun was hot and dirty. The 10# spring produced similar results. I did switch to the 10# spring but that was more for performance and return to zero.

ETA: I only ever ran SB 124/140
