Ruger RSMs were 1:14. I wonder why such a divergence in twist rates. My CZ has no issues even with 400gr TSXs.
A good principle to guide me through life: “This is all I have come to expect, standard lackluster performance. Trust nothing, believe no one and realize it will only get worse…”

The CZ is shooting well with 400 TSXs. May try it in cold weather also. Also, Mule Deer's opinion that twist doesn't affect a bullet after expanding is comforting. Guess I could shoot into some newspapers and test that.

I have only shot an Elephant with mine. Barrel has been cut to 21" and has a Brockman laminated stock. I used only Woodleigh solids and the accuracy and performance was exemplary. I would use that combination on anything that walks.

I have shot a couple of Cape Buff with the 400gr Original X bullet and some monolithic solids in my CZ550 416 Rigby and so far they have all performed well, for ME. Model 70 guy from here was with us on the 1st, and wildly successful on all counts 24hrcf Safari in 2006 and he had a 400gr X bullet veer off course in one of his several buffalo shot on that trip.
I will never forget, while hunting with mike (Model70guy) us sneaking up to within FIFTEEN FEET of a snoozing cape buffalo bull in double thick brush, and the PH then THEN THROWING ROCKS AT HIM! to get him standing so we could look him over! It worked, by golly, and the bull had soft bosses so we did not shoot, but I was glad that all three of us were carrying 416 Rigby's.

You would have had doubts as to its wisdom at the time. I sure did.

I am sure you are familiar with the "Terminal Performance" thread, Micheal has pretty much conclusively shown that the 1-16 twist is too slow for optimal penetration with 400 grain mono metals.
I got banned on another web site for a debate that happened on this site. That's a first

EXCELLENT Observation, JWP! I had forgotten about Michael's stbilization tests. I will adjust fire accordingly! Good thing I have a good stock of 400gr A Frames and Woodleigh solids.
