I would suggest gas checked bullets. I am unsure if you were using them or not.
Also you need to have a good heavy crimp. Too loose and the bullet will jump in the cases of the unfired rounds. And H110 will not ignite properly or should I say not as good.
There are many variables to check also. Bullet Diameter, Bullet Hardness. Brass length (whether they are the same)
and many more that I cant think of at this moment.
Keep trying and be safe
