Hi gang! Today I was gifted 3 50 round boxes of this ammo from a local Sheriff who I became friendly with. It appears to be highly regarded from what I have gleaned on the net, but I have a question about it's application. I am an elder with a preference for revolvers. It's hard to teach an old dog new tricks. I think I would like to standardize on this highly rated cartridge, but would like to hear input from those members more sophisticated than me in that area. I presently own three(3) revolvers that will accept these rounds: 1) a 2" Model 36 no dash, 2) a 4" Model 10-6 HB and 3) a 6" Model 19-3. At present, I only use factory loaded Remington ammo in these home defense revolvers as follows: Mod 36 158gr lead SWC, Mod 10 158gr +P SWCHP(FBI Load) and the same in my Mod 19. I think the Mod 10 could digest this ammo without concern, but question the safety of it's use in the Mod 36 and the Mod 19(forcing cone cracks). If this Speer product would allow all three revolvers to use the same load, it would make things more simple. I welcome your replies, thanks for reading this long winded post
