So I ordered some .359 175gr. Ranch Dog bullets from Carolina Cast Bullets. They were out of gas checks at the time so they sent me 7 bullets to sample. They look amazing...they shot amazing well with 8 and 8.5 grains of Blue Dot. My issue is with only 7 bullets to test I loaded 4 with 8 grs. and 3 with 8.5. After shooting the 8 grs. there was some mild leading. After 8.5 there was a streak for most of the length of the barrel. I measured them with my calipers and the measured .355 & .356. However, this is my may home cast bullets measure also...so I'm starting to wonder if I need to upgrade.
P.S. This is out of my S&W 6" 386. I really want these to work for my deer hunting load. What can I do? Please help!
