Old post, but I'm bored. Picked up some of this stuff a few weeks back for a new toy. I'm only carrying 5 rounds, so the weight savings is minimal, but if your toting around 10+ rds, the weight can add up. Liberty 38sp 50gr ( 44 grams ) and Remington 158gr lrn ( 75 grams ) …..two different animals here, but it's all I have.
