So I tried some .429 Barnes Tac-XP bullets for 44spl in my Henry 44mag/44spl rifle. I pushed a bit and velocities were in the 1500fps range.
Went to clean my rifle today and my patches were coming out the darkest blue I have ever seen them. I ran 2 patches, let it sit for 20min, 2 more, let it sit for 20min, still super dark blue. Put the bore scope in and the lands were covered in copper for about half the barrel. And that is after 2 soaks. I pulled out my dedicated copper remover, which is bore safe, its soaking now.
I have had some copper buildup here and there. Its generally minimal to nothing. And I have fired this gun primarily with JHP, and using the same bore cleaner it generally is light blue, which goes away after a 10min soak.
I have heard Barnes are bad about copper fouling, but this seems to be a bit much.
