Sorry for not being specific: the ammo would be for my .357 sp101, which is the gun I carry when I'm hiking in WA. I have a bunch of Cor-bon safety slugs in my closet, and due to their really light bullet weight they're probably lighter than the Blazers. They're what I load my gun with when I feel like carrying around town or at home. I usually carry Federal Hydroshock when I'm on the trail, and I'm wondering if Blazers would be a decent alternative. 158 JHP with slightly lighter shells sounds interesting to me.

I know we're probably talking a total weight savings of a fraction of an ounce for 5 or 10 rounds, but the experiment might be worth it especially given the price.

It looks like they have "clean" ammo in .38+p. Not exactly powerful, but I wonder if it would foul less than their normal loads.
