Thread: Straight wall nitro cases. Who uses filler and what ?

In your straight wall modest capacity cases who is using filler and what with nitro loads ?

I'm talking about cases like 45-70 and 45-90 that have more than enough capacity when using nitro / smokeless powder.
38-55 and such like don't count because it's a pretty small case anyway.

I use dacron and wool as a filler in my big capacity cases with nitro for black loads.
But those cases are massive and the nitro load is only around 50% of case capacity.

I have come across varying opinions lately about the use of toilet paper to hold nitro powder back around the powder for better ignition and cleaner burn in this application.
Also varying opinions on crimping bullets to get better ignition and burn also.
Crimping not an issue for me as exclusively using single shot rifles

Thoughts ? Experiences ?
