What are the largest diameter .177 pellets

What indoor disciplines have a power limit?

We impose one due to damage to the Bisley target holders. Even at 6 ft lb the 3mm replacement steel plates bow outwards half an inch after a year or so, but open sights Airsporter type guns shot standing often hit the holder frames and do real damage at 10m. Our target stands are 15mm fibre board on 6mm mdf and shoot through at 12 ft lbs.
At 6 yards even 6 ft lb rifles hitting sprung plates splash lead back and I've felt hot lead on my face several times.
12 ft lb on a bell target would be asking for trouble.
ISSF dont have a limit at present.

That was what I was wondering about.
