I am just beginning to test the performances of my1917, when the barrel is warm the gun is very precise, my problem comes when the barrel is cold, the POI is higher about 2,5" and gradually decrease with the following shots, actually I use the following reloads: 55grs of IMR4350, lapua167 scenar moly, CCI br2, Sellier&Bellot brass. Is there any way to contain or eliminate the problem or should just try to controll it by using leaner starting shots?
