What you need is a better sabot. There are some that will make that loading managable and not a fight to the finish. In fact, how was the accuracy with a sabot loading that tight? I use the Harvester Crushed Rib sabots for about 75% of my sabot shooting. I also have some Nosler and some Thompson Center that fit tighter, but most my rifles like the crushed rib.
Accuracy wasn't too bad. I was 2 for 2 during deer season so that is good enough for me. I don't consider myself a good shooter but my groups were 2.5-3" at 100 yards with a Nikon Omega scope. I don't judge my shooting by a piece of paper, I judge it based on how full my freezer is, so as long as it hits the vitals of the the animal in my scope is all I'm concerned about. If I neededa quick reload for either of the 2 I shot I might as well forget it and wait for the next deer to show up. That is one reason I may switch from the BH209 to the T7 pellets, reloading time for me was much faster with the pellets. I don't care much for the crud ring and residue it leaves compared to the BH, but every powder is going to have its pros and cons.
