After fighting mine for months and finally sending it back to cimarron for repairs it 'seems' to be working ok now. From what I have read they seem to prefer a longer bullet of a tapered nose design with a flat nose but not a real big flat nose. Overall cart. length seems to be 1.600" to have the best chance to feed correctly. I am still looking for a correct bullet. I am checking with Accuratemolds.com at this time.
