QuickLOAD has this wildcat on file. Always amazing me what they have...

On the capacity did you measure that with H20? It's close to what QuickLOAD has on record (73.00gr) since case capacity is a sensitive metric, I just wanted to check before I over ride the value.

You wouldn't happen to have the make and model of the bullet? I just get the warm and fuzzies if I can use a bullet on file rather then altering an existing.

Whats your barrel length?
