That's a good point about barrel length. If you ever participated in a 5m BB program you know the challenges they have with muzzle control.Thanks! I’m pretty sure I’ll stick with the 350. I have a few 243’s I am planning to give him when his LOP increases and he becomes a more serious shooter. We hunt primarily in the woods and at close (100 yards) ranges and I like the heavier bullet option. I don’t reload and 350 is readily available here locally. I agree, I think with it being suppressed the shorter barrel may be the way to go. As he grows, and starts to hunt more I doubt he will continue to suppress and I would assume the short barrel is not liability or more dangerous to carry and hunt with for an inexperienced hunter? Seems like it could be but obviously will do my part in educating him in proper gun safety, etc
