DocGKR has evaluated the following loads out of a 5" S&W 629 revolver and 16' Marlin 1894P carbine:

Federal 180 gr JHP (C44B), Federal 240 gr JHP (C44A), Federal 240 gr JHP Hydrashok (P44HS1), Federal 300 gr LWC Cast Core (P44E), Hornady 180 gr JHP XTP (9081), Hornady 240 gr JHP XTP (9085), Hornady 300 gr JHP XTP (9088), Remington 180 gr JHP (R44MG5), Remington 275 gr JHP Core-Lokt (RH44MGA), Speer 270 gr JSP Gold Dot (23968), Winchester 210 gr JHP Silver Tip (X44MS), Winchrester 250 gr JHP Partition Gold (S44MP)

Out of all these loads, the Hornady 300 gr JHP XTP (9088) was judged superior to all others, with deep penetration and expansion in excess of 0.70". Other comments: "The Hornady 240 gr and 180 gr loadings also performed well, the Remington 275 gr Core-Lokt was a good overall performer, the Remington 180 gr and Winchester 210 gr Silvertip loads had excessive muzzle flash, the Hydrashok fragmented badly, the Silvertip did well in the revolver and not the carbine, the Gold Dot did well in the carbine and not the revolver, the Cast Core has VERY deep penetration, but no expansion".
