I have a 243 Howa in a heavey barrel. This gun was shooting great for the past 6 mouths. Over the weekend I took it to the range and my groups went from 1" or less groups to 3". I have been loading them the same all this time. But from time to time I will try another weight bullet. For the load I thought I had worked out for this gun was 87 gr. Hornady with IMR 4064 36 grains.
Any idea why my group has gotten so much bigger.
