Is there any testing that has been done on this? The temp that the shell is keeped at may be the best improvement in patterns that we have left, we did the barrle, we did the shells, how about the temp. of the shell. we wait for 60 degrees to test our loads, What if it is 30 when hunting?
If we heat the round up 30 degrees, do we get 30 % better patterns? Even if you got 30 more pellets in the 10 ring. How about when the temp is 35 degrees and the shell is 90 degrees? This needs to be checked out. The guys from BPI used to put there goose loads in a playmate cooler with heaters back in the early 80's because the loads they shot were much stronger when kept warm.
