That particular type of ammo is Good Friend .44 S&W Magnum. Not sure of the grain weight of the bullet. But, the brand is rare and wonderful. Sincerely. bruce.
I vaguely remember having seen ammunition using bullets with this style of hollowpoint. IIRC, it was in .357 S&W Magnum ammo. Have spent quite a bit of time this morning looking to see if any current RP is loaded w/ such a hollow point. There is a slight similarity of this ammo w/ Golden Saber but it is not the same. Possibly these are component bullets that were hand loaded into RP cases. HTH. Sincerely. bruce.
