Tried both the 50 cal Barnes(Traditions) 250gr Expanders and Barnes spitfire 285gr in my Omega. I loaded with great difficulty one Expander. The spitfire I pushed done about 5 inches - quit trying and pulled the bullet. Expander had a red sabot - Spitfire had a yellow. Gun was clean but for 2 caps.

Is there a better sabot for this bullet or should I try something else?
