The 225 gr Barnes is a fairly long 44 bullet at 0.89" in length. When it comes to stabilizing a bullet it's the bullet length that is the determining factor. By way of comparison my 44 cal 310gr cast slugs are 0.85" long and they are stable in a 1 in 38" twist barrel, but just stable. The length of the Barnes copper bullet may be at the limit of stability.
Have you tried firing a group at 50 and 100 yards? The bullet stability will be quite obvious then.
I haven’t. I shot at 25 yds at the range and didn’t notice anything odd. I will have to try it farther. 50 maybe. It has open, ghost ring sights. 100yards ain’t gonna happen.
