hello everyone i'm new this forum...
i am looking to get a good long range gun but yet have decided what i i want... i am in the info gathering stage of this process considering i just bought a bushmaster varminter 5.56/223 and the power to be (the wife) just about had kittens at the price of the gun... so i would like to get as much info on the calibers i am interested in before i start buttering up the powers to be 
i am interrested in the 6.8 spc, 308/7.62, 6.5 creedmore and the 6.5 grendel. eventhough i can't hunt with a semi auto gun in pa i live close enough to ohio and west virginia that can use it for hunting but for the most part it will be used to put holes in paper and maybe some long range shooting compition. i am hoping to keep my choice within the price range of my ar and get with a 20 to 24 inch barrel.. so any and all info you all have i would like o hear it... thanks |

From what I understand the .308 and the 6.5 creedmoore are both AR-10 sized cartridges and the latter are AR-15 cartridges. That leaves you at a fork in the road already, do you want the rifle with the 2.81" cartridge-overall-length or the rifle with the 2.25" cartridge-overall-length(COL)
With an AR-15 receiver you can get uppers in .223, 6.5 grendel, 6.8 spc, .300 whisper, .458 socom, .50 beowulf, and many other calibers I neglected to mention. With a .308 build, you have another fork in the road. You can get an LR-308 or an AR-10. The AR-10 is Armalite's baby, the LR-308 is a DPMS build. As far as I know the main difference is in the magazines, some use the M1A/M-14 magazines and the others use AR-10 magazines. As far as effective range goes, if you want a long-range gun I suggest you stick with the .308, you can lob bigger projectiles with more energy and still retain semi-auto function better than if you were to try and accomplish the same task with the .223. With the .308 length receiver you can also get an upper for the 6.5 creedmore, which is also a precision shooter's cartridge. However for plinking or general range time, it can be costly to shoot these 2 cartridges. But, if you are a reloader, or like to collect uppers, there are also many cartridge choices you can use with the .308 length receiver. Just about any case that was based off the .308 cartridge would be feasable to build an upper for, it leaves you with a lot of powerful options like 7mm-08, .260 Remington, etc. |

thanks powder_burns,
you are right that does leave me with alot to think about as to which fork in the road i want to take... i guess i'll have to do lot more research on what i want and what i want it for... as far as uppers go that might be a way to go in the future |
