That sure is an interesting looking bullet. Would love to see how it performs. Before you get into a jam, no pun intended, you really need to use a Hornady OAL gauge and determine at what OAL that bullet engages the rifling. This is doubly important in all copper bullets. Some 300gr hollow points when loaded to just fit in the magazine, say 2.26 OAL, turn out to be jammed into the rifling. Don't get me wrong. Bullets seated to just engage or even push into the rifling a little bit are some of the most accurate loads you can produce. Not always, but more often than not. The key factor is the increase in initial pressure early in the ignition cycle. That phenomenon has to be allowed for in choosing a starting load. For smooth sided bullets, it also introduces an additional concern and that is not having the bullet pull out of the case when you extract it unfired, leaving a mess. Every reloader should have an OAL gauge, especially those who use bullets without much of a track record in the caliber they're using. From a real world standpoint, I have yet to encounter a 450b bullet with a ballistic tip, that engaged the rifling without being too long to fit in an AR magazine.
