I may have to take my original comment back.
I tested this stuff in my CZ 455 stainless standard barrel last week. At 100 yards out is well under 1". Due to my unimpressive first couple of tests, I wasn't holding out much hope but I had a box along and stuck in 10 rounds to make sure it sucked. The first group was great. 10 more. 10 more. And so on until that box was gone. Thinking it might be a fluke, I grabbed another box the next time with the same results.
The first time I was shooting it in a 452 and 457 during the summer. I think it was probably 25°C. This time with the 455 it was -3°C. Not sure if it would make that much of a difference but when it finally warms up and the wind dies down, I'll try it again.
