I'm just starting to load for my desert eagle 50. I know h110 is a good powder but I have alot of lilgun sitting around collecting dust. I'm loading speer 325 gn bullets. I'm curious if any of you guys have used it? How many grains? It seems to work in most rounds that use h110 but it seems to use a little less with the same results. I'm struggling to find any info in my books. Hornady is using it in their book but for 300 gn bullets. Any help would be greatly appreciated.

I have no experience with that round. All I can tell you is that QuickLOAD thinks that a charge of Lil' Gun that is about 1.2% lower than a charge of H110/296 will produce about the same peak pressure, slightly more velocity and muzzle pressure, and therefore a bit more recoil. It looks to be a couple percent more bulky, so you'd have compressed loads at a lower charge weight.
hornady lists a load using lilgun but its for a 300gn bullet. Start at 24.3 and max at 31.7. How much of a difference is there going to be on a 325 gn bullet? The manual is showing a max h110 at 33.7 for the 300 gn and I know that the max for the 325 is 32.4. There is definetly a difference in pressure with a heavier bullet. Thanks for any help.

Figure the ratio will be about the same, so 30.5 for Lil' Gun. QuickLOAD got 31.78 for the H110, so very close. 30.5 is less than the 1% difference QL predicts, but owing to bulk, it is the value which it will provide 100% case fill without compressing, so that may be how they came to draw that line? Using QuickLOAD's 1% it became 102% case fill, so, a bit compressed. If Lil' Gun doesn't like being compressed or is difficult to compress, that would explain it.
The reasons for the adjustment are two fold. One is that a heavier bullet provides more inertial resistance for the powder to build pressure against, so the case volume doesn't grow as rapidly for a given pressure, so pressure rises more for a given amount of burned powder. The other is that the bigger bullet eats up more space in the case, so you are left with less room to put powder into.
