| Does anybody have the barnes manual for the MRX bullets? My dad is shooting a 140gr MRX with 66gr of IMR4350 and it seems a little hot for his gun. I was wondering what the max is for this bullet. I believe its a longer bullet than the other 140 grainers so the pressure will be higher. Also how much of a difference will the temperature make on the pressure? He shot 2 rounds saturday morning at about 40degreesF and they had flattened primers. He shot again saturday afternoon at about 70degreesF and the case looked fine. |
