My point is, a stock doesn’t make you a better shooter on its own. Spotting shots with a suppressed 6.5 is easy for any shooter who applies proper fundamentals and actually practices shooting with virtually any stock.
A stock designed properly and adjusted to the shooter properly can definitely help with a lot more than just muzzle rise, but by itself it’s useless if a shooter doesn’t know what they are doing. Which is why I asked if you were being honest when you stated that you couldn’t spot your shots easily with the factory stock. Something tells me your are exaggerating like everyone does online.
My wife is 105 lbs and shoots a suppressed 6.5 tikka with the factory stock with vertical grip. She also shoots a non suppressed .243 Tikka with factory stock and vertical grip. Has zero issues spotting shots and quickly putting 2nd and 3rd shots into big game and targets when needed. Quickly meaning within seconds of taking the first shot never losing her sight picture. Are you saying this isn’t possible for you? Fundamental work is likely in order if that’s the case.
To answer your question, I’ve never had an issue spotting shots with the factory Tikka or Sako stocks, or any of the aftermarket stocks I’ve used on over a dozen tikkas and sakos in 6.5 chambering and below. Kills as close as 30 yards and as far as 1,100 yards on big game animals.
And guess what, I still plan on buying 2 or 3 rokstocks as soon as they are available.
