[QUOTE="ducky, post: 2493393, member: 94420"] You have a lot of choices, there are a bunch of wildcats based of the .223. I personally have used 6X45, .25-45, .277 Wolverine, and .300 BO. The middle two were strictly AR-15 rifles, the last one in BA and AR. My two favorites are the 6X45 and .300 BO and the reason why is bullet selection and suppressors. I built my Savage 6X45 with a 1:7 twist so I can pretty much handle any bullet out there, but I do run out of magazine space. It does shoot 55 grain bullets gaster than a .223 by 200 +/- fps, and 70 grain bullets equal a 55 out of a .223. My long range hunting bullet is a 100 grain Sierra GK with a MV of 2700 fps, and I use the Sierra GK 80 grain HP as a second choice. The .300 BO is just a lot of stupid fun shooting subsonics suppressed. In a bolt action it basically sounds like a springer air rifle, in an AR all you really get is noise from the action cycling. It is so popular that there are a lot of great bullets made for it both for supersonic and subsonic use for hunting. I've killed two deer with this cartridge using 125 and 130 grain bullets, and I've finally got some 190 Sub-X Hornady bullets to try this fall from the deer stand. I've shot steel to 400 yards with this cartridge, but I'd really try for 200 yds or less hunting. I really like the .277 Wolverine, but finding bullets like my favorite 90 grain Gold Dot is hard. And since you shorten the case to get things to fit in the magazine the 130 grain bullets run out of steam to quickly IMO. We never got 3000 fps from 87 grain bullets in the .25-45 and once you go over 100 grains you start to loose out to the magazine length. I have the .204 Ruger as well in a slow twist factory rifle, I find it just okay. However, it lacks the versatility of the .223 so I rarely find myself using it. Also my 6X45 is a better LR rifle than the .204, with bullet BC always beating the velocites of my .204. I'd build a fast twist rifle if you do anything in a .20 cal, and I'd probably opt for the Pratical. [/QUOTE]
