My Omega is almost as tight as what you are describing. I finally went to Hornady bullets with harvester sabots to be able to load them. Powerbelts load easy and I am in the middle of trying the Sabretooth from harvester. I ran a light polishing with JB bore paste (200 strokes up and 200 down) which helped a little. If you have a stainless barrel they seem to be slightly more difficult to load due to the nature of stainless when it is machined it tends to leave rough surface compared to 4140 steel (my Omega is stainless).
