[QUOTE="swampratt, post: 4194753, member: 15054"] I got a 6.5 CM and was not impressed. I really thought the velocity would be higher than it was with the 140 gr bullets. 22" barrel I suppose does not do it any favors. I like short barrels and some testing I have done with Ruger American 22" vs my 18" savage Model 10 showed me the model 10 barrel is a fast barrel. Lets say you did get lucky and got a fast barrel. Some trajectory math I had Shooters Calculator do. All 24" barrels load data from Hodgdon .308 at 2900fps with 155 ELDM. 100 zero 10 mph wind. Yards below 200 : -3.29 400 : -27.42. 600 : -82.07---- Drift 29.02 ----1136 energy. 6.5 CM 24" 140 ELDM 2780 FPS 200 : -3.50. 400 :-27.81. 600 :-79.90-----Drift 20.58---energy 1241. 6.5 CM again with 123 ELDM 2900 fps is easy to get. 200 : -3.23. 400 : -26.69. 600 : -78.92.---Drift 25.86----energy 987. I put the 123 gr in there because I hunt and found smaller more fragile bullets put the smack down on deer -hogs and other critters. My favorite round is a 55 V-Max in an AR or bolt rifle 2700-3200 fps. Nothing gets up from being hit with that in the right spot. 500+ lb hogs included. Like was stated already pick a bullet for the job at hand. I will put this here if I can't make an accurate load for a rifle it does not go hunting with me. My hunting rifles stay under 5" at 500 yards. The .223 is the winner for my rifles with under 1" at 300 yards. Deer and pig shots for me 95% of the time are under 200 yards. Neck shots. That heart or double lung sends them running. If you want to anchor under 300 yards on a deer with .308 or 6.5 go heavy and bust right through both shoulders. 178 A max was awesome as is the 168A max. for tearing up shoulders. I have done that and it sure puts the minus on the table meat. That is why I went light and neck shoot them. One last note. Some deer do not know they are dead yet and keep on trucking. Every one of them I shot in the neck knew they were DRT. [/QUOTE]
