The practices I use for casting match quality bullets has been in a state of flux these past couple years. I’m still learning.
A new mold came in last week and it caused me to work with a bottom pour vs ladle cast and Linotype vs #2 Lyman as I worked with the bullet to bore fit.
For the past year or so the only bottom pour I’ve done was with mass production 9mm & 7.62’s. All .308 match bullets were ladle cast using Linotype, single cavity brass.
For whatever reason I’m starting to think that bottom pour allows more consistent mold temp, more bullets per hour and just as consistent bullet uniformity.
Swapping #2 for Linotype made a difference in bore fit with the softer alloy. Barely noticeable in dimensions but where Linotype stuck in the lands, #2 extracted. No data +/- regarding accuracy.
What are the pros & cons of ladle/bottom pour, Linotype/#2. Or is it just personal preference. I’d appreciate your thoughts. Bill Cook.
