Tight bullet fit is not necessary for great accuracy. Some of the best shot groups occur with "slip-fit" conicals. My T/C Renegade 58 is a perfect example. If my index finger was long enough, I could load my bullet without a starter or ramrod.

On another note, having difficulty loading your 3rd Powerbelt means you need to swab between shots more often. Powerbelts do prefer a fouled bore, but not that fouled...lol.[X(]
