I have done (and posted here a while ago) the actual chronographed testing results of the Buffalo Bore 158 grain +P LSWCHP-GC ammunition. Out of my personal model 2" 60-7 Chief's Special the velocity averaged 1037 fps. Out of my 3" M65 1086 fps. and out of my friends 2" Dick Spl. 1043 fps. Not only incredible, but it was incredibly consistent with a variation of only a few fps between shots from the same gun.
The results posted by the OP did not specify barrel length nor did it state that he actually personally chronographed them. I will say that I am a huge BB fan and I have no personal interest in the Company other than the fact that I am a customer and like what they do, but I will go so far as to make this statement:
Buffalo Bore's ammo is just about the ONLY ammo I have ever tested that ACTUALLY does EXACTLY - OR MORE than their advertised claims and ballistic charts state. Again, the results I chronographed above are from actual guns, not test barrels or 6" barrels. I can not say the same about the ammunition produced by Rem, Win and Fed because they are not even close!
If Tim Sundles (Pres. of BB ammo) can do it I am sure it can be duplicated by someone else as well, but they would have to stumble onto what the BB "formula" is. All Tim will state is that he has a special powder blend, but he obviously is not telling anyone else! We all know what the chemical make up of Coca-Cola is (like it or not) and it is plainly stated on their label, but NO ONE in a hundred years has quite duplicated it's exact taste.
I would certainly like to test those loads personally in my own guns through my Chrony. I am not currently a user of Power Pistol Powder, but if I cross paths with some I intend to give it a whirl.
Thanks for posting.
