Hey fellas,
I don't want to start a war but I am looking for a little real world information. I am pondering adding a new caliber to my AR world. I already have everything short of a barrel for another upper. I have been looking at the 6.5 Grendel, but it requires it's own brass and different mags. I was hoping to keep things as simple as possible so I am leaning away from that. I have a ton of .223 and 5.56 brass so I would like to be able to use that as a base for the new round. That has me looking at the 6x45 and the 25-223. My main uses would be ground squirrels, rockchucks (ground hogs for those of you back east), coyotes and some steel targets. I want to be able to reach 500yards with plenty of energy. I will be using bullets is the 75-87 gr range. I have other rigs that I use for lighter and heavier bullets. I am thinking a 20" barrel will be what I go with for the extra speed. So I am looking for a little input and some real world velocity numbers for bullets in that weight range from both of these rounds so I can run some ballistics on them. I am leaning toward the 6x45 because I already own a .243 so I have bullets and the dies are commercially available. However, from what I have gathered from reading numerous threads in multiple forums (besides a huge headache and lots of lost time) it seems that the 25-223 can get better velocity out of the same weight bullet. I know that the BC is lower in this scenario but that why I am looking for some velocity numbers so I can run them through the ballistic calc. I would appreciate some feedback from those of you who have actually used these cartridges. Thanks! Russ |
