9MM Range Officer

Thought I would post an interesting observation. A friend wanted to shoot a local IDPA Classifier with my RO. He used 147 gr Berry bullets that he shoots out of his G34. His OAL is 1.135". About half of his bullets tumbled. I shoot a 160 gr bullet with an OAL of 1.200". It stacks bullets with that load. Load them long sports fans if you want the best accuracy.

What was his load? If he loads the rounds down to much the bullets will tumble, or at least I have experienced the tumbling with 147 gr lead bullets in some of my 9MM guns.

He loads to a 130PF. His bullets shoot just fine in his G34. They also shoot well in my Wife's G17 and G34. He uses Titegroup. My go to load back when I shot plated bullets was a 147 gr with 3.0 gr of TG.

What is his OAL as I believe the Glock has a shorter chamber, I load out a bit longer to a 130 PF and have no issues with tumbling. I'll check the OAL when I get home this evening.

My Trojan 9mm likes longer loaded bullets. Only bullet I've had problems with is 147 lead. Tumbled in ,y Trojan and Glock 34. Only had problems with one box and have shoot thousands but it was enough to not purchase any more. Little research and several others have had problems from varied casters.

I load a 160 gr lead bullet to 1.150" out of a Glock.
