I had loaded up some 162 Amax bullets for my Stevens 200 in 7mm-08. I had loaded them to 2.925" OAL - about .025" off the lands - and they shot well, about 1 MOA. I tried seating them back to 2.875" so they would fit in the magazine, and the shots were all over the place, 2-3 MOA. It seems odd that the bullets would be that upset by an additional .05" jump, or is that how they perform?
It was also in the 30s today, and in the teens when I shot previously. I was shooting 39.0 grains of IMR 4064, so I would expect a slight increase in velocity in the warmer temperature, but I would think not enough to through the shots so much.
