Cant find load data:

You can also email Hodgdon and ask them for data. They sometimes have data not published because of space constraints they are willing to share.
I agreeWarning: The data above is for a jacketed bullet, not a lead bullet ... I suggest you not use that data.

OP did not post specifics of lead bullet type (commercial or homemade), alloy mix, hardness, sizing, lube type, etc. and we need more information before posting OP could use jacketed load data for lead bullet, especially for high pressure caliber like 10mm.Lead bullets will give LOWER pressure than jacketed with the same load.
I would say go ahead and use the data as long as you do not get leading.
You could load 180 gr Lead FP bullet to 1.250" (or your max working OAL) with start charge of 5.7 gr and test 6.0, 6.2 gr and see which powder charge will start to reliably cycle the slide and then monitor for accuracy trends and leading. You can always go higher while watching leading of barrel.10mm 180g Lead Flat Point with Winchester AutoComp ... Cant find load data
Well, I stand corrected.
Still, it's good idea to start low then go up.
That's all and good for someone doing this for 50 years but new reloaders should be pointed at proper data or at least warned the data is not tested. Just because you do it doesn't make it right for anyone else, especially a new reloader.Using jacketed bullet data has been a standard practice for over a century.
Other than Lyman, most manuals do not even post lead bullet data. Why? Because any powder and charge safe with a jacketed bullet is safe with a lead bullet.
In fact, the older Lyman manuals point this out. I've been doing it for over 50 years without incident. It's been standard reloading practice for a century.
And new reloaders also need to learn that you check several different manuals, especially Lyman. Individual Manuals are a guideline, not holy scripture. That's why we own, and check 3 or 4 of them.
