From what I gather, I.S. rules allow 24.5 gram loads.
The ordinary load used is labeled 24 grams.
24.5 grams equals 6.91/8 of an ounce. Not quite 7/8 of an ounce.
If you are running late on the second target, a skeet choke may be a bit thin.
Although, probably not worse than shooting NSSA .410 doubles.
