Graybeard,I killed 2 whitetails yesterday about a hour apart and both shots were pass thru but no blood til bout 20 yds from where they finally died,these were killed from my omega in-line,I was shooting 777 magnum with a 245gr power-belt, and now I am going to start using my grey hawk I recently purchased , I am shooting it with 100gr. of 777 powder and a 245 power belt I do have a old box of 385 grain Buffalo bullets but the lube is dried up on them , can I clean it off and still use them,in the grey hawk? I dont know much about conicals so what do you think I should do?
