From my understanding, the handi's have quite a few differences from a bolt gun. I have read on this forum that:
1). They have way to much free bore to ever get close to the lands like a bolt gun.
2). They have to be shot dirty while bolt guns need to be clean.
3). If you set the forearm on anything without a washer under it, expect stringing, usually not a problem with a bolt gun.
4). You need to keep the latch clean, well a bolt don't have a latch.
5). There a bunch I've forgotten.
Most handi's won't shoot factory Hornady V-max loads. I could throw them better than mine shoot them. I have a buddy that has a CZ 204 that shoots anything you put in it under 3/4" and most under 3/8". I have never heard of a handi doing that. My whole reason for starting this thread was to zero in on the handi's unique loading requirements. Don
