Airgun Technologies Agt uragan 2 30 cal question?

Hey guys I’m currently looking to buy a Agt uragan 2 in 30 cal can’t decide on the 600 or 700mm version. Can the 600 be tuned to run like the 700 while still getting 40+ shots talon tunes lists the 600mm at 60 shots and the 700 at 50 shots is that about right
Depends on what your using it for i would go with the 700mm that way your covered whatever you need to do
 
Like kpac said all depends on intended use. I went with 500 mm .30 Vulcan 3 as it will strictly be for hunting and the out of the box 75-80 ft/lbs is more than adequate . All depends on how much power you need which will be determined by use. The 700mm will always be capable of being tuned higher than the 600 due to 4 more inches of runway to accelerate in.
