All brass hulls

[Jim Schultz]

Harry, I agree that is why I used the term"best suited for black powder." I know of one guy that uses Mag Tech hulls with pistol primers/smokeless powder and he is happy with the results. I have a box of the now defunct Double Hammer brass hulls, which are modified Mag Tech hulls with bored out primer pockets that accept a 209 primer and are fitted with a base wad. They are much lighter than RMC hulls and I use them with 1 oz. card and fiber hunting loads. The only issue that I have had with Double Hammer hulls is that a base wad dislodged. My fix was to crimp the hulls just ahead of the base wad and so far I've had no more problems. My two favorite powders in either Mag Tech or RMC hulls are IMR4756 and Trail Boss. There are 5 loads in all and Tom Armbruster (815 385-0037) at Ballistic Research Inc. has tested all of them. Tom tested the IMR4756 pressure/velocity loads for Double Hammer and gave me the Trail Boss loads via telephone.
