How low will you go regarding FPS on your hunting boolit for deer or American big game? I read that if your cast boolit can explode a 1 gallon jug of water then it is good for meat hunting, and the distance it only splits the jug is the maximum distance for a killing shot. I am working on finding my 45 colt 1894 Marlin a boolit mold so I can hurl some lead next year.
