You can try, but I doubt you can crack the crack!!
Mine did it up to the 165 RCBS sil bullet.
I have loaded up some Lyman cast bullets in the 120 range, and cranked up the speed. This helped me the most. If I recall correctly, they are sized .310.
Only problem I have ever had with my gun is cylinder locking up due to high primers or long brass. I have to trim my brass religiously so I don't have to worry about whether a round will load in it.
Good Luck and enjoy that gun.

P.S. If you see an extra cylinder for one, let me know!!
