I used to reload .357 with 110 grain and 125 grain bullets using slower burning powers (WW 296, Hogedon H110 and Hercules 2400) and fired them out of a 2.5 inch S&W 19. The muzzle flash was unbelievable !!!

in italy there are a lot of pouders:

-american products are very expansive.

-best product like vithavoury N320\N340 0,5 kg 37 euro

-less expansive rex-32 (born to use in 12\70 shotgun with 32 grams of lead)
1,0 kg 25 euro

-B&P MBx36 (good italian product for 12\70 shotgun 36 grams of lead)
1,0 kg 45 euro

in short barrels I prefer hight velocity burning pouders.

in the same revolver with slower burning pouders:

-vithavuori N110 19,5 grains 110 grains fmjfn bullets:
1192 ft\sec 48 kgm

-vithavuori N110 16,5 grains 142 grains fmjtc bullets:
1112 ft\sec 54 kgm

more expensive loading, similar performances, the muzzle flash was unbelievable too...
