Interesting about the 1-11" twist. I had a custom 7x57 with a 1-11.5 twist, which was not my choice but the gunmaker's. He asked me what bullet I'd be mostly shooting, and I specified the 140 Partition--but didn't tell me about the twist, which turned out to be quite a surprise when I tried 140-grain Barnes X's. That's when I measured it.
The other interesting thing is that while the rifle shot 140 Partitions well, the 7x57 that shot them best (as in five, not three, in 1/2" to 3/4" at 100 yards) was one I stocked myself in New Zealand-grown Juglans regia, on a VZ24 action with a 21" Shilen barrel with a 1-9 twist.
All of which is just one of many examples of why I ceased trying to "match" the twist to the bullet many years ago.
