I am considiering a 300 whisper but would like to ask a few questions first. Is it difficult to find a subsonic load that is consistant and accurate?
Would you recommend a gun built on an AR or a bolt platform? why?

I was thinking of using 220 mk's, would I need an 8 twist or something different?

How accurate can these be, moa or 1/2 moa?

Thanks Shane
