First, 357 sig is my caliber. I have been carrying Corbon 125 JHP's for years. They are awesome on animals and the couple times I have shot them through 4 layers of denim into gallon jugs of water they had explosive power and expanded between 0.70 and 0.80". Today a lady gave me about 30 gallon jugs so I thought I would experiment with 4 layers of denim. Well two out of the three Corbon bullets did not expand with cloth and plastic clogging the hollow point. These over penetrated as well. I then shot three 357 sig HST's and all three expanded to around 0.64" and had proper penatration. They did not have the same explosive effect as the expanding Corbon. I then shot three Buffalo Bore 125gr 357 sigs with the proper Speer Gold Dot bullet. These leave my G32 at almost 1450fps. The effect was explosive on the first jug and all three expanded to around 0.58" with proper penetration. I only have about 60 of these left and BB is not loading with the correct bullet now, nor is DT. I know these are not scientific tests. The thing is that I have been unable to get any Corbons for a while and they start making them again this week. I have $400 worth on back order. I think I would still like them for woods carry but I am very concerned about PD. I am thinking of cutting back my order and maybe carrying the HST's for personal defense. Any thoughts?
