I have some 9mm FP bullets. I've never loaded these type of bullets before. They are 124gr. Berrys. I dont have data specific for these in my manuals. Can anyone give me some tips?

And you won't. You will load them like a lead bullet. They have a longer bearing surface than a RN so you'll want to back off any 125grLRN data you use. Seating deepth will be the biggest problem. They will likely not seat out near the 1.135"-1.150" OAL you see w/ other bullets. Your pistols chamber may have a slightly shorter throat & the sharp shoulder of the TCFP will engage the rifling before the round chambers completely.
Set up a dummy round to test for fit in the chamber. I would start w/ 1.120", expect to go slightly shallower. Then you can either use 124grJHP starting data from a sim. shaped JHP or 125grRNL starting data & work up.

Back when ALL Glocks were G17s, my friends and I discovered some nifty 147 gr. LFN projectiles, there was little data available for anything other than jacketed bullets. We basically developed our own load (I don't even remember what it was), but the secret was keeping the load under 1000 FPS, we had minimal leadding and shot thousands of these. Nowadays, most bullet manufacturers can provide you with load data for their products.

Find some Lead Data for 124gr lead bullets. Load the bullets you have to that starting data. I like to load my stuff to 1.130" most the time. Make a round at your desired length and drop check it in the barrel to be sure it works with the rifling. Besides checking for any oddities of your barrel and this bullet type it should an easy thing to load up with lead data.
