What are the largest diameter .177 pellets

Can't see the point of 7 fpe, what do you use it for? be over the 6 allowed for a lot of indoor disciplines and not really high enough for outdoor shooting at longer ranges. .

What indoor disciplines have a power limit?

Possibly try something with a softer skirt, perhaps some AA Diablo? With the lower energy available, you want a head that will fit on the lands of the rifling, but not be too indented, otherwise you will waste to much of that precious energy. A soft skirt that fits into the rifling should provide a seal with the minimum of friction I would have thought?

If your just shooting card at short range with modest power, a light weight wadcutter might be worth a try - RWS Hobbies for example.

What indoor disciplines have a power limit?

I don't believe they do. But many indoor, especially club, 10M ranges are set up for .177" rifles at under 6 ft-lbs or .177" pistols at 2-3. They very often have formal or informal restrictions on either power or calibre, or both, because they don't want some bloke turning up with a .25" Rapid Seven and blatting their backstops and target holders to bits.

For example, the last time I was on a club 10M match pistol range, the range rules specified .177" wadcutters only. I think if I'd turned up with a 5.9 ft/lbs pistol, even shooting .177" wadcutters, the club officials would probably have made it clear that I was not obeying the spirit of the rules and would I please go away and take that big noisy denty thing with me and come back with a proper match pistol.

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.

Ta Peter.

That was what I was wondering about.
