I am 0 for 2 on my last two bullet posts so let's try on more. Here is an unlisted bullet that I am curious if anyone has any information on. It measures 0.550" x 0.810" and has an ogival / paraboloidal cavity that is 0.34" deep. The profile and size somewhat resemble a Burnside but there are obvious differences including the rings and large cavity. The bullet also somewhat looks like a "Joslyn" MM470 (yes I know MM470 is not actually a Joslyn) with a ogival cavity. The base is concentric and there is zero evidence of any carving. This one was reportedly dug in Triune, TN. Any thoughts?
