I have shot some buck or maybe it was deer slayers a 300gr hollow base kneraled semi conical 50 cal bullet . It perfomed decent at the range although I've not usedit in the field.

Are there others out there like it or is it a 1 of a kind ? I like the lubed bullet "self sealing" base full shoulder contact bullet shape and a dead soft 50 cal only needs to on its mark to be leathal ....Right?
