Very short barrel subminor but Certified Ammo

[-JCN-]

I wanted to use a P365 at a match with Syntech 150. 
 

I don’t think out of that short barrel it’ll make 125 power factor. 
 

Am I reading the certified ammo rules correctly that I just have to be within 10 power factor of sample ammo with certified ammo for it to be legal?

 

So if they sample test at 130, I would be okay with a 120?

 

As an aside, I can make 125 PF shooting Lawman out of a P365 with a threaded barrel….

In addition to possibly not making power factor, bullets that heavy have difficulty cycling compacts reliably. They also have fat ogives that causes feeding issues in barrels with short leads. I would just stick to 115 or 124g with compacts.
