I seem to read the best 45-calaccuracy reports using the 270 gr. Powerbelt,195 gr. Barnes Expanders and 200 gr. T/C Shockwaves. Since the sister toyour failed 200 gr. XTP is the Shockwave, I don't recommend you try that one again. Try the Cabelas Dead Centers in 220 gr. or Extended Ranges in 235 grain.
