Using unique and 115gr plated rn Im going with jacketed hp 115gr middle charge powder or the 120 gr lead rn powder weight but their oal is 1.05 one is like .905 or somthing ...Winchester white box is 1.15x on avg ...does oal differ with powder weughts? If 1.15 is perfect in my guns should I do that or should I do like lyman says and set oal to .1 less than winchester
