I just finish testing a new Lyman 260gr Devastator HP with gas check cast bullets and my older 240 gr.RCBS Sil gas check bullets from my S&W Mod. 29 8 3/8" Barrel...


S&W Model 29 44 MAGNUM 8 3/8” BBL

260 gr Lyman Devastator HPGC 0.431"
16.2 grains Blue Dot
CCI 350 primer
COAL seated in cannelure 1.692"
Velocity 1370 fps 8 3/8” BBL
Energy 1083 ft/lb

245 gr RCBS Silhouette GC 0.430"
16.2 grains Blue Dot
CCI 350 primer
COAL seated in cannelure 1.654"
Velocity 1360 fps 8 3/8” BBL
Energy 1006 ft/lb

Very accurate loadings, velocity was consistant for both bullet types. All cases extracted easily with no sign of excess pressures and primers were looking good also.
The RCBS Silhouette cartridges have been loaded for 20+ years.
