The 158 grain Buffalo is soft cast. Gel tests I have seen have been O.K. - should go 12" to 14" but may fragment. Since it is easy for me to suggest ways for you to spend your time and $$$, please try the Buffalo Bore hard cast 150 grain stand pressure wadcutter, it should go about two feet and the Cor-Bon 110 grain DPX +P - I'm sure it will preform well/best of all if expansion/penetration is the goal out of a 2" barrel. I like the 150 grain wadcutter which should out-penetrate anything out there in .38 special even compared to +P loads

+1 on BBs hard cast 150 gr. Works the best in a 2 inch or under revolver.
