  1. The mold throws good ... review by Nils on 6/12/2017

    The mold throws good bullets. I\'m having some success with them in my 7-30 Waters G2 Contender using Hornady gas checks. Cast from straight wheel weights they weigh 142 grains lubed & with the gas checks in place. No jacketed bullet performance but good for light plinking/short range varmint hunting loads on the cheap. The best I\'ve gotten so far is a 2.6\" 100 yard group using SR 4579 with the bullet seated way out, just deeply enough that they don\'t get stuck in the barrel when I open the action on a loaded chamber. One grease groove is outside the case neck. No leading so far, I\'m still testing. Aren\'t we all?
