I just loaded and shot 20 Barnes 375gn XPB's in my 500 Smith today. I was wondering if anyone else here has used these.
I went with 44.5 gns of AA-1680 for a start. They were the most consistant shooting cartridge I've loaded to date, and I've loaded hundreds. I came home and loaded 20 more with 45 gns of AA-1680 to shoot tomorrow.
I had to dig pretty deep in the dirt pile at the range to find a couple of the fired bullets but did find two of them. They were nearly the exact same shape as they were when I seated them. They appear to be extremely good for deep penetration. However they did not open up like I expected they would. I'm going to shoot a few through jugs of water to see if they will open up in liquid.
