Yup, made me forget all about 10mm, etc. 230 grains going 1K fps. All for the cost of a recoil spring, a mainspring and a $15.00 EGW FP stop. My all-steel Kimber likes them just fine, though shooting many of them is a little hard on my wrist. I shot enough to verify function and accuracy and since then just shoot regular 45 ACP. They work fine in the gun, though if I was shooting a lot of ACP I would pop in a lighter recoil spring.
I could load them even hotter if I wanted to. 1K just seemed like a nice, round number.
