I have an older, Investarms .54 Hawken. I want to get a mould for it. What mould size should I get?
Thank you for your input. I will do as you suggest.Before @Flintlock Whiskey buys a $70+ mold, he should buy a $25 digital Vernier caliper to measure the land to land diameter and the groove to groove diameter. Then subtract 0.010" from the land to land diameter for a suggested ball diameter close to the calculated diameter.
Patching will be groove diameter - land to land diameter and divide by 2. Add 0.005 to the groove depth for patch thickness and you have a good start to begin load development.
Calipers are a worthwhile investment for inside dimensions, outside dimensions and depth.
