[QUOTE="Pizzaman1, post: 1983167, member: 109976"] Does it chamber? Use a headspace comparator to measure headspace of the new brass compared to the newly resized brass. Try seating your bullet a little deeper to see if it fits in the case gauge. It looks like you are using a very high B.C. You said it chambers. Now- have you measured BTO, using an O.A.L. gauge? to make sure your not "jamming the lands"? If you did, and your'e not jammin the lands-send it! Did you measure the C.O.A.L. for that particular bullet? Measure your BTO on the one that wont fit. Take an empty case and another bullet and seat it deeper into the case- work in .005" increments. Measure it in your case gauge- if it looks like its fitting better- your bullet is long and bottoming out on the case gauge. It looks like a high B.C. bullet they are long and the ogive might be your problem. If it's chambering and not "jamming" the lands" -send it. [/QUOTE]
