Re: Will a 1 - 11.25\" twist stabilize a 190gr Matchking?
I have shot 190 SMK's through a 1-11.25 twist completely stable out to 1K at a starting velocity of 2600 FPS. This was also at 88' and 15 degrees F. You will have no trouble at your velocity.
FYI if you calculate the best twist for a 190 SMK using various stability factor calculations or calculators you will find that 11.25 is prime for the 190 and a stability factor of 1.5 which is just right.
Long range shooting is a process that ends with a result. Once you start to focus on the result (where the shot goes, how big the group is, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
