What are the heaviest and best slugs for the umerex gauntlet SL .30 that will still work in the magazine?

64 grain Patriot hollow points just barely fit. Getting decent results with them. Best speed seems to be at the low to mid 800 fps.

Griffin 64 HP fit with some wiggle room, but not much. They are very consistent!

I just sold some of these to a gauntlet owner last week. Awaiting feedback:

Beeswax lubed. Cast from an Accurate 30-070A mould with a hollowpoint conversion.
