jrtmasp Posted March 15, 2013 Report Share Posted March 15, 2013 (edited) I just wanted to get opinions on what other people have purchased or experienced with various calibers for ARs other than 5.56 and our wonderful .308. I would love to have certain ones, such as 6.8 and a .458 but the benefit doesn't offset the cost (IMO). The 300 AAC blackout is gaining more and more fans but I've never fired it. I have a few coworkers that have made the move to it and like it. It also seems to be cheaper than many options, especially when it comes to loading your own. I'm just gathering opinions because I plan on a SBR down the road next year or the following year and I don't want it in 5.56.

imschur Posted March 15, 2013 Report Share Posted March 15, 2013 Well I have a 300 blackout, 45 and 9mm. I love the option of the cheap handgun ammo. I love my dedicated .22 upper too :) Quote Link to comment Share on other sites More sharing options...
EasyEJL Posted March 15, 2013 Report Share Posted March 15, 2013 I like the idea of the .45acp, out of everything in the "other" calibers that's what I personally would build. great for suppressing, and with the right loads its reasonably safe for home defense use too.

Tripledeuce Posted March 15, 2013 Report Share Posted March 15, 2013 My wife and I have uppers in .223, 6.8, 7.62X40 wt, 30 hrt, 6.5 Grendal, and 260 remington. I'm working on a 338 Federal for the wife for pigs. I really like the 7.62 Wilson, the 30 hrt, and the 260. The wife is in love with her Grendal.

jrtmasp Posted March 15, 2013 Author Report Share Posted March 15, 2013 (edited) Well I have a 300 blackout, 45 and 9mm. I love the option of the cheap handgun ammo. I love my dedicated .22 upper too :) Interesting options. I completely agree with you on being able to use handgun ammo as an option is a big plus. I'll do a little research on the 9mm. Did you build it yourself? I would go all in for a 45 ACP but I have a secret obsession with buying an HK USC and building a 45 AR would put that on the back burner. I have heard some good things about the Hi Point rifle in 45 ACP and its cheap. However, I've always found that you get what you pay for. My goal is two more AR builds before I branch out and invest in other rifles. I have to fill this nice new big safe I bought last year after all.

StainTrain Posted March 15, 2013 Report Share Posted March 15, 2013 I own ARs 5.56, 300blk, and 308. I just passed up a decent deal on Noveske 6.8 barrel and bolt. Quote Link to comment Share on other sites More sharing options...
survivalshop Posted March 16, 2013 Report Share Posted March 16, 2013 I like my 300 blackout & I was liking the idea of a 6.8 , may build an upper just for it . Quote Link to comment Share on other sites More sharing options...
StainTrain Posted March 16, 2013 Report Share Posted March 16, 2013 I keep waffling on the 6.8. Just when I'm about to do it, I start telling myself that the .308, 300, and 5.56 has all my bases covered. I haven't taken my .270 out of the sage in two years. That being said, I keep pondering, if the 6.5 (or 264lbc) could get a little more standardized, I would probably consider hat. Quote Link to comment Share on other sites More sharing options...
jrtmasp Posted March 16, 2013 Author Report Share Posted March 16, 2013 The tough part is seeing if some of the big boys are playing ball with certain ammo. The 6.8 feels a bit forced but certain names have invested in it and seems good. The 300 BLK is following suit. The 6.5 is nice too but I would also fear about its longevity.

Longevity is certainly a concern. I am no expert but its seems like the industry's acceptance of the caliber has been hampered by drama between Alexander Arms and Les Baer. Please jump in a correct me if that is off base. Quote Link to comment Share on other sites More sharing options...
Dane Armory Posted March 16, 2013 Report Share Posted March 16, 2013 I have several calibers 300wsm, 270wsm on the LR308 lowers and 22lr , 9mm , 6.8spc on the AR15 lowers. Project pistol caliber guns being built are .357sig , 40s&w , 10mm auto all waiting for BCG's. The 6.8spc is my favorite and most accurate caliber but ammo is scarce and expensive. I will end up selling one gun or an upper , dont shoot it much anymore can't afford to feed 4 hungry mouths. The 9mm is the fun plinking gun but the range is 50 yards. Past 75 yards and its a 6 to 12 inch pattern. I will also be building a 300aac blk, got the barrel but that is it. The WSM calibers are a novality , rounds are $2+ each and I had to taylor the handloads to 95% power or they wont cycle. But the range is 1000 to 1200 yards and velocity is from 2900 to 3900fps. Also made heavies at 200gr and 220gr in the 30 cal. I always tell people to do a caliber thats different but feasible. Try something like a 38 super in an AR pistol now that would be a fun toy and cheap to feed! Quote Link to comment Share on other sites More sharing options...

Robocop1051 Posted March 16, 2013 Report Share Posted March 16, 2013 I was researching a 10mm build. My ammo supply kinda dried up. So I might consider a .40 cal instead now. Although a 9 and 45 are always resting in the back of my mind. I've read about a few people building 7.62x25 as cheap plinkers. I see that cheap ammo is drying up now too. Besides .223 and .308, I have a 300blk, 7.62x39 and 22lr. I'm very impressed with how affordable 5.7x28 has become. I have tossed around the idea of a pistol/SBR build and one of their uppers. What I would ultimately love is a reliable 12 or 20 gauge upper! Quote Link to comment Share on other sites More sharing options...
shepp Posted March 16, 2013 Report Share Posted March 16, 2013 thought 22LR was the way to go just for blasting, until a month ago. that 45 that tom was talking about and posted about looks intresting. also i was watching a show about the 338 fed uppers how they bolt on to 308 lowers and can use the same mags plus they are lighter which sounded great for hunting purposes.

jrtmasp Posted March 17, 2013 Author Report Share Posted March 17, 2013 I came across an Armalite 50A1 at my local gun store today. I had never seen one up close before. What a nice looking rifle. It was on display for a $100 per ticket raffle. I passed on that one. Now that is off topic, Robo. Anyways, I keep coming across lowers marked multi caliber. Is that just a special term being used for a lower that is capable of anything that doesn't require a bigger mag well? Quote Link to comment Share on other sites More sharing options...
edgecrusher Posted March 17, 2013 Report Share Posted March 17, 2013 Pretty much. For me, the 5.56 and .308 cover my rifle needs, and I want to get a dedicated 22lr upper (whole AR rifle?) for training…… http://www.spikestactical.com/new/z/st22-16-22lr-upper-w12-bar-and-fake-can-p-1014.htmlhttp://www.spikestactical.com/new/z/st22-16-22lr-upper-w12-bar-and-fake-can-p-1014.html ….. thanks for that one J. I would also be interested in a .45acp upper, but only if they got rid of magazine capacity restrictions here (you know my pain there), and only if I could find an interested buyer in my HK USC….. maybe you know someone????

Hitman Posted March 17, 2013 Report Share Posted March 17, 2013 7mm Express and 280 are the same cartridge. The 284 is a rebated rimmed cartridge with a steep shoulder angle and short neck. Some people have good success with the 6.5X284 wildcat version. Quote Link to comment Share on other sites More sharing options...
jrtmasp Posted March 17, 2013 Author Report Share Posted March 17, 2013 Ha...Don't tempt me Edge. If you still have it w/i the next 18 months max, I may definately take you up on that offer. After my .308 build is complete w/scope in the spring next year, I will be in the market. Just in time to save up for the Tromix buy in 2015 too, if I'm lucky. I keep a strick and busy gun buying calender lol. Quote Link to comment Share on other sites More sharing options...

Also the 6mm284 is a smoking round and very accurate Edited March 17, 2013 by Magwa Quote Link to comment Share on other sites More sharing options...
