@skipdavidson How quiet is your 6ix vs the likes of a TB Ultra 7?Slower is fine, just watch your terminal range and wind deflection.
The last two guns I built were an 18 in Clymr 6.5 PRC and 20 in Magnus 7LRM running Gunwerks 6ix and 8ight cans, respectively. The speed trade off with size is completely acceptable.
