I won't make any call one way or the other. after watching some bullet shockwave videos it's pretty obvious a brake does cause significant changes to the gas flow and pressure waves behind the bullet. Will Quickload model the back pressure curve in a barrel with and without a brake after the bullet exits?

I pulled the bolt apart cleaned and lubed it yesterday also. It ejects great, just won't chamber the next round. It sounds right also, I had a soft cycling .223 that sounded similar and was cured with 20 rounds of some really dirty ammo after soft cycling about 200 rounds of Varget handloads. I think we are just talking a fraction of an inch here

After the next range session if I cannot get it to cycle or group I will test Sanders CS. He sounds pretty like a stand up guy on the phone so I am optimistic it will be cured one way or the other.
