I guess I missed that they were SWCHP. I recently bought some to load for my 642 revolver. So far I've gotten bullet jump on the 5th bullet almost 100% of the time. The bullets measure .357, just not tight enough in the cases. Last I fired were loaded in GI cases, they are a little tighter, still got a little jump on some of them. This being said, the bullets were accurate and hit the target perfectly straight, no tilt or keyhole what so ever. Out of the 2" bbl they prolly weren't doing 700 fps. I didn't shoot any over the Chrony. They do have healthy recoil in the 642.
