I read in one of your posts that your BM barrel started to shoot in cold weather. I was wondering if you changed anything from before like, different ammo, different speed like faster or anything. I have a BM barrel that also want shoot in cold weather. It shoots pretty good in hot weather. Thanks for any help. Mickey:(

Last summer, I added weight and retuned, and went to faster ammo. It shot fine and I thought that the faster ammo and heat had made the difference. Last week, trying to decide on new ammo for this year and what to shoot at the indoor competition last weekend, I dug that gun out and shot it. I fully expected it to be a waste of good ammo. It shot great with the test lots (slow), I tried the fast stuff I shot last summer and it shot great and then I dug out the ammo that I know shot keyholes last spring and it shot great. I have no inside information, I just rang the barrel and added enough weight to move the null to the crown, and then ran the tuner again.
