I've got a High Standard M4 and want to get something larger for deer / hog hunting. I like the ballistics of the 6.8 as it's close to my .270. But my buddy was expounding on the virtues of the .300. I can get a complete 6.8 upper for around $550 (bushmaster) and really think that's what I want.

Pros and cons accepted gracefully since I'm just beginning research. Thanks for your help!

i have both 300 ACC ( 762x35 ) and 6.8spc uppers for my M4 and ar pistol.

the 6.8 is a fairly potent round good report and recoil compaired to 300acc or 556.

the 300acc, has just about the same balistics as 762x39.

Deer get taken with 556 and 762x39 often... so the power is there. 6.8 will get you some more range with that power.

I like 300acc because it uses regualr ar mags...

I like 300acc and 6.8spc because they aren't 556 :)

when buying 300acc ammo.. what out for whisper.

thanks gd. I ended up buying Remington #700 in .243 A nice older rifle with iron sights still & made in the 80's, I think. Gotta check the serial number.

Appears to have been made in 1984

Don't give up on your AR project, I built a couple of 300 Blackouts and just love shooting them with supersonic ammo (usually load a 125 gr bullet). It is a short range cartridge but will knock a feral hog on it's butt. As previously indicated the only thing you need to change is the barrel (in theory).

I really want the 6.8 SPC for the longer range and the .270 ballistics. I'll get it done just a little later
