i guarantee that NO ONE has tested max pressure of a mini action besides the factory. ONCE AGAIN, we DO NOT recommend pushing the limits of any cartridge beyond what is SAAMI spec. To retain the warranty, factory ammunition must be used. I cannot tell you how many instances we have had with people and their hand loads. Be safe, as noted by Bluntforcetrauma, what do you really gain by the added pressure?
