It doesn't sound like you reload and you might try some different ammo to see if the rifle functions. I have a 16" J&T and it shoots the 123 grain AMAX without any problem. I have reloaded ammo which exhibited the same problems you described. I traced this to the bullets being seating to long and the bullet contacting the rifling. Seeing how the 123 grain AMAX was designed to work in the 6.5 Grendel and has an optimum taper/ogive of the bullet I'd say the ammo is out of spec or your chamber is out of spec. Trying different lots of 123 AMAX or different factory ammo may give you an indication where the problem lies. Its possible the rifle is still very tight and just needs a few rounds to break in. It's not unknown to have magazine problems cause feeding issues with the 6.5 Grendel. If I bought different factory 6.5 Grendel ammo and still had functioning issues I would immediately be on the phone to J&T.
