I was quite impressed, finding an entry in a USA website, with pics.. a load of 7gns of Bullseye with 150 gn cast bullet, possibly a Loverin, shot at 50 yards.. 19 rounds in a single hole of about 3/4 inch.. not sure about the rifle.. I will try the same with my Marlin.. I have a lot of cast bullets and some Bullseye.
