No, you just shoot for no score or recognition. Definitely not a DQ.
Appdx C2 39
If the resultant power factor fails to meet the minimum power factor floor
for the relevant Division, the competitor may continue shooting the match,
but not for score or match recognition.
So this rule means that any ammo used be hand loaded?
Actually, what it means that your ammo and gun combination must meet the required minimum power factor as you have declared when you sign up for the match, as measured by the chronograph procedure. The rules don't make a distinction as to hand load or factory - for the reason one could take reloads, pretty them up and stick them in factory boxes and claim "I'm shooting factory". They're both treated the same at the match.
Every competitor must validate their ammo shoots through their gun at the required power factor. What we are suggesting to everyone is don't make the assumption that just because it is factory produced ammunition that it will shoot the required power factor. Many will with room to spare, but it depends on the gun, length of barrel, the manufacturer's variances and whole host of factors down to the weather an even your altitude above sea level on how ammo will perform. It's best to validate your gun and ammo configuration with a chronograph than to make that assumption.
