I have a PH with supposedly short-short chambers.

About 1/4"
The 2 5/8" 10ga has less internal volume than the 2 7/8". This means less filler wad is required. Heavier loadings like 1 5/8 and 1 3/4 ounce may not be possible (or advisable). A plastic wad may not be able to sit deep enough to allow for a star crimp, forcing a roll crimp or the trimming of the petals to make room for a star crimp, or use of nitro card and filler wad combination instead of plastic wad. Use the 2 7/8" Sherman Bell recipes that are low pressure and experiment with the filler wad to get the shot column height correct.
Us Short Ten and Shortier Ten reloaders are a little more on our own than loaders of other gauges. The good news is that big hole is very forgiving.
