Another thing that will cause tipping is when the bullet enters the transonic region.

The 732 has a low BC and could be shedding velocity enough to be in that zone. That type of tipping can still be pretty accurate though.

It would help if you could chronograph the load but, it's perfectly safe to raise your powder charge to between 14.8 and 15.5.

14.8 was my most accurate load in my 32/40, Douglas, 15 twist but, using a spitzer.

I shoot those bullets in my CPA at 200m, but with black powder in a 1:14 twist barrel.  They alway tip a bit for me except in summer when the air is warmer.  The faster I shoot them the less they tip.  That bullet does seem to tip more than others for me, but it has shot pretty well.

Jagfolks, I have that exact same mould for my CPA 32-40. And yes my bullets tip also ? Less tipping when I increased the IMR 4227 powder charge but less accurate ? Infact the Saeco mould even with the tipped bullets were still more accurate that the Hoch mould that Paul Shuttleworth sold me with the rifle ? The Saeco bullets are more difficult to seat with my plugged 32-40 case.

I found the same with both my .32-40 barrels.  One is a Douglas and the other is a Badger.  My Hoch 322200D doesn't fit either barrel well.  The Saeco 200gr works well in the Badger barrel.

  I had Steve Brooks make a nice .32 cal mold with the shank of the Saeco bullet ( but changed the band diameters a bit ), and the nose of the Hoch.  It is a lot less tippy.  Often the Saeco is still as accurate in the Badger barrel, but the Brooks one looks to be very good in the Douglas barrel.

Thanks fellows! I neglected to mention that it is a 32-40 and I will up the load a little and give it another try as soon as the snow melts again. These bullets do breach seat easily using a plugged case not that it improves "operator error"!
