I have this mold and have loaded the bullets in a 35 whelen,a 358jdj and a 35rem. I shot the bullets thru a stack of phone books and got about 7.5" (seven and a half inches) of penetration after flattening the noses.Un flattened ,they went about an inch deeper. They went thru gallon detergent bottles like a drill as RN's but exploded the jugs when flattened. My alloy is the same BHN as lyman #2. Linotype lead and some shot.in case I decide to heat treat it. IF i were going to use this bullet for deer hunting ,I,d use plain old wheel weight alloy! If the bullets did not fill right, I'd add a little tin(50-50 solder) ,about 3 to 4 ounces of solder to 10 pounds of WW .Add more solder if that does NOT do it.Check out cast boolits . com for more info! BTW, Those recovered bullets fired into phone books at 100 yards weighed 208 as fired and 146 recovered. About 65% retention. 14 inch Contender barrel 35 Rem.
