NCTURBOS Posted June 20, 2013 Share Posted June 20, 2013 I purchased a M4 about a month ago and am finally headed out this weekend for the first shots fired! From what I've seen/read on the board here: --Keep it very well lubed (wet) during the process! --Use high velocity ammo, preferred slug or 00-buck. 1.) Will higher velocity #8 shot work during the break-in, 1325fps? 2.) Can I use #6 steel shot in the weapon? Factory stock choke tube... Thanks, K.
