Don't expect to find 1oz loads for the 10 with the same pressure as 1oz for a 12. Bore capacity of a 10 is only about 13% more than for a 12, so for comparative loads you are only looking at 1 1/8oz in the 10 to be equal to 1oz in the 12. 1oz loads in the 10 are more comparable to 1 1/8oz in the 12.
