[QUOTE="JTH, post: 2723093, member: 59647"] I can give you some comparison of H4350 vs Varget with the 123AH in 6.5 CM. I’ve got a Cooper Raptor in 6.5 CM, it has a 22” barrel and tends to show signs of pressure earlier than what others are seeing in this cartridge so your results will likely vary. Data below was all on a COAL of 2.857 With H4350 I started at 40 grains moving 2653 fps and worked my way up to 42.1 grains moving 2777 fps with an es of 6 fps and no signs of pressure With Varget I started at 38.0 grains running 2693 fps and worked my way up to 42.0 grains running 2923 fps and definite pressure, blown primer. 40.7 grains of Varget got me to 2830 fps with an es of 6 fps Obviously your rifle may be different, start low and work your way carefully up looking for signs of pressure. Both powders produced 0.5 moa groups. The 123 ah is a great bullet for the CM, bangs steel at 500 yards with consistency. [/QUOTE]
