Thread: Sub - X load - Case filler needed?

So stumbled across Sub-X load data on the Hodgdon website for the 190gr using H4895 - though at 13.3 grains. There's no mention of any need to case fill - but, having just thrown 13.3 grains into a 308 case - there's a lot of empty....!

Has anyone else played with this load? Am i overthinking that using a case filler is a must in this instance?

I'm not really keen to throw plastic down the barrel to be honest, though keen to find an alternative to Trailboss for sub loads...

Have contacted Hogdgon for their views on their views..

Your thoughts please.
