I experienced them exploding out of my 44 mag. Way to soft. Loaded to hot. I also found that the consistency was all over the place. I avoid BB now at all costs. I've not had luck with any of there stuff I've tried and found the workmanship to be quite poor.
I've tried it in 4 calibers now with all the same problems.
I use Underwood or DT and find they are much better all the way around for "custom" factory loads.
I no longer own a 44 mag.
I have a box of their .44 magnum "Reduced Recoil" which is a
bit of a misnomer, in my opinion anyway. I wonder if I just should not shoot them at all. Why take the risk as I've heard their load may be a bit hotter than necessary.
