How does cold affect point of impact?
For a load that was worked up in the summer (80+ degree weather), what, if any, effect will the cold (below freezing) have on the expected point of impact?
Last year I used the FPBs for hunting. I had good success but wanted to see if I could work up a better accuracy load with the Speer GDHP in the 240/250 grain range, both .44 and .45 caliber. I’ve got a couple of bullet/sabot/powder loads that work well in my Omega X7, but they were all shot in pretty hot weather. Particularly because of the plastic sabot, I am wondering if I need to get out to the range on a really cold day to see if there is a difference. Maybe load up and let the barrel get really cold before shooting.
Anyone with experience on this?
[edited to correct poor terminology as pointed out by Sabotloader - Thanks!]
