I have several very accurate maximal loads for the Barnes XXX and am interested in trying their MRX bullet. My question is what has anyone's experience been with the MRX bullet? Ignoring the OAL question and cost, were you able to use the same powder? increase or decrease the powder charge? increase of decrease in velocity? increase or decrease in accuracy? has anyone actually used these bullets on game and what was the result and at what range? Thanx in advance for sharing your experience, assessment, and recommendations.
