Thanks in advance Muzhunter
I like to get less than 20 to 30 ft/sec Extreme spread and Standard deviations of under 10.
10 to 15 is good for SDs.
These are not easy to get but are possible.
For 100 to 200 yards 60ft/sec will work but when you extend the range you will need to
improve it to prevent vertical stringing.
If you shoot 10 rounds in a row (Without Cooling between shots) make sure that the round
doesent stay in the chamber long (Cooking) before shooting it.
