Here is a design that I have been kicking around for the many Mosins out there, it is a 203 gr flat nose that would make a great hunting boolit. The check will be flush with the base if crimped into the top grease groove or will be just inside the case if you seat deeper to the top drive band, this design also lends itself to seating at the second drive band for worn throats. When seated to it's normal depth the OAL should ride right at 2.780.
The only thing I see we may want to do is make the bands .316, I kept the grease grooves deep so they can be sized down to .311-.312 and still hold plenty of lube for those long barrels. Let me know what you think as my first buy is headed to a close and I am looking to start another.
