Overall Length?

What do I do if the bullets I want to use are listed as FP (flat points) but all the reloading data I can find is for JHP or SWC type bullets?

If the ammo is intended for a semi-auto, you have to choose an OAL that feeds reliably. Start with starting loads and work up from there.

I thought the overall length had more to do with the amount of bullet that is in the brass so as to not cause pressure issues? But okay... I'll try some experimentation with dummy rounds when the time comes.

"What do I do if ..."
1) You can find a different reloading manual that lists the OAL for the FP's. You can never have too many manuals.
2) A more cost effective approach would be to ask here giving the specific caliber and bullet (brand and type). I would be surprised if someone hasn't loaded your caliber with your bullet or at least has a manual covering it.
3) Call the bullet manufacturer. Almost all of them have someone on staff who will give you good advice.

So what is the problem? A FP won't be more than a tiny bit different length than a JHP or SWC of the same weight. If you're not starting out with absolute maximum loads, you won't have any problems.
The gun doesn't know or care what the front of the bullet looks like. It only cares about the bullet's weight, material, and how much of its shank is in the case.
You can use jacketed data with lead alloy bullets. Don't use near-max lead data with jacketed bullets.

With all due respect, John, I have to disagree with that approach - with a novice to reloading. I have no doubt that you and I could handload those bullets at or close to max and make some safe rounds without opening a single book. But, I dare say we have a full lifetime or more of reloading experience between us.
We don't know what caliber he is talking about. Let's say it's a 45 ACP. I have some bullets in that caliber that are more than 1/10th of an inch different in length. That's not an insignificant difference when talking OAL if you use your implied suggestion that the OAL's for both can be the same as long as you don't load at or near the max. That's especially true if you go the reverse route and load an FMJ using FP data, for example.
Might as well do it right at the beginning and then, after the knowledge base is available, he will know what he can and can't do safely.

Point taken. My apologies. Mal H is right.

41 Magnum
I ended up ordering Remington Cases and some Hornady XTP 210 Grain bullets since I do have data for that.
If anyone has used West Coast Bullets and has data for that, it would be appreciated.
West Coast has not replied back yet either.
And they are being used in a Desert Eagle, so lead is a no no.

Amazing how a little extra information changes the picture! I can't speak for John, but I sure thought you were talking about lead bullets.

I like using powders (in ALL calibers) where a serious overload (> a proof load) is impossible. In the 41 mag, 296/H110 and slower (wc680/ Accurate 1680). In the .270, for example, 4831. Try the slowest powder that will give the desired velocity. This is a good mindset for the beginner to get into. It will stand him in good stead forever.

Revolver rounds are usually loaded so that the case mouth can be crimped into the cannelure on the bullet. If the bullet does not have a cannelure, then load them to the correct SAMMI specified OAL. For 41 Magnum the maximum OAL is 1.580". Since they are being used in a semi-auto, some adjustment of the OAL may be necessary to achieve reliable functioning.
