What would it be for 22 cal? Mine is a 40 grain VMAX. They shoot GREAT in just about ALL 22 caliber center fires. They work in my 22-250. They are a NATURAL for 223 Remingtons. 222 Rem loves them too. A 40gr VMAX is ldeal in 221 Fireball. l even shoot them in a 10'' bull barrel TC Contender 22 Hornet. Those 40gr VMAX will even topple a 55 pound IHMSA RAM @ 200 Meters from that Contender with a high hit. Prairie Dogs simply go to PIECES when hit with a 40gr VMAX
