Yes.Are they ok to use
Maybe. It depends on how close you are to "max" powder charges now. You said you "want to start" loading for the .45ACP, so just start low and work up - just like you would if you could find regular large pistol primers.will I need to reduce powder charges?
I tend to follow the path of judicious caution: when any major component changes, drop back to the lowest known good, safe charge and work back up to the most accurate load that meets the needed velocity for the intended purpose.
I'm assuming you mean large magnum Pistol primers?I want to start reloading 45acp but can only find large magnum primers.

I don't think a powder has a big impact on those things, more of a slow powder light bullet issue. Same conditions that eat top straps... my purpose for the powder was pushing 170s and 180s in 357, so more of a specialty powder on my bench.I don't think using magnum primers would damage the breech face.
I've read where people had lots of problems with LilGun powder screwing chambers and forcing cones on revolvers.
I read that and threw what LilGun powder I had left in the garbage.
You can use it but know that the magnum primers were designed to have a longer and hotter flash when using larger capacity cases using slower burning powders ensuring total ignition of the powder. For this reason the ignition of a magnum primer that lasts longer will produce more gas and can increase the chamber pressure without necessarily effecting muzzle velocity. As recommended above reduce your loads and check for pressure signs.
In 45acp pressure signs aren't a usable thing. On top of that you can't read primers either..You can use it but know that the magnum primers were designed to have a longer and hotter flash when using larger capacity cases using slower burning powders ensuring total ignition of the powder.

But one can tell the difference during recoil as well, every time the slide slams to the rear, and I've had primers blown off the case.In 45acp pressure signs aren't a usable thing. On top of that you can't read primers either..
While I agree Lil'Gun is offensive for handgun ammo I really think it shines for .357 Magnum ammo with a heavy bullet shot from a levergun.I don't think using magnum primers would damage the breech face.
