Does anyone have a source of reload data for 2.5" 12 gauge.
Components on hand: Fiocchi hulls, Cheddite/Nobel Primers and Clays powder and I'm roll crimping the hulls

I often trim hulls to 2 1/2 in then use 2 3/4 inch data (typically 1 oz or 1 1/8) and roll crimp the seal.
As a rule of thumb I stay under 8,500 PSI.
The number of 1oz loads that will fit is huge. My favorite hulls are federal gold medal and federal paper.

I always start with Hodgdon's website. In the Lyman 5th edition there was no 2.5" load data and very limited Fiocchi load data. Same for BP's 9th edition High Performance Loads for Clays

Hodgdon's online reloading center has 2 1/2" data for several hulls. You should be able to find something workable in 7/8 or 1 ounce. https://www.hodgdonreloading.com/reloading-data-center

Try Lyman's shotshell manual. Should be some there
8d look, but it's not handy in the orchard right now

I loaded a bunch of Fiocchi shells trimmed down to 67mm. That is slightly longer than 2 1/2”. It is 2.6378”. 2.5” is 66.04mm. So less than a mm longer. Why you may ask? 65 and 67mm CIP shells are approved for use in 2 1/2” chambered guns in proof. I was able to load with standard wads, common powder and Fiocchi primers. And I can load them on my progressive loaders.
I have sent several strings of test loads off for testing pressures and velocity. Until I get those results I’m just waiting. But I used Unique powder in a 1 and a 1/16 ounce loads with loads which would have been very modest with 1 1/8 ounce. For what I shoot 1 1/8 ounce is overkill. Unless I get extreme velocity variations I will be very happy. Everything fits, I can get more of what I need and don’t need to stock yet another special use wads.
You can roll crimp a 2 3/4 “ load in a 2 1/2” hull. But Fiocchi are not that long to begin with and there is a lot of internal volume in that straight wall case. Trim few down and try loading them at 67mm. Have them tested for pressure and velocity. Being able to just use a normal star crimp speeds up loading from a box now and then to loading hundreds an hour. And I had two 8 pound jugs of unique powder on hand.

this is very much dated information, and it's prime utility is reserved for those who have ratholed some of the old dupont powders....but, for those of us who meet those qualifications, this is a gold mine of low pressure data. michael's post regarding the use of 2 3/4" data in 2 1/2" hulls with roll crimps, opens the door to many useful loads - IF YOU STAY IN LOW PRESSURE TERRITORY.... http://pdf.textfiles.com/manuals/FIREARMS/imr_reloading.pdfbest regards, tom
