I've never had issues with either of them, just never gotten either of them to shoot all that well in anything, especially LilGun. Buckshot looking groups is about all I have ever gotten with that stuff. 🤷♂️ Longshot wasn't bad, but just not as good as other powders.
Only handgun powder I recall really ever having "issues" with is HS6, and that was consistent ignition problems across several different cartridges.
