Does anyone have any experience with this caliber?

[okrattler]

I've been throwing around the idea of buying a 6x45 barrel for my AR. From what I gather I wouldn't need a new bolt or new magazines or anything except the barrel. Which I do like but this isn't necessarily something I absolutely need but more of a want type deal. Realistically would it be worth it going from a .223 to this caliber? I already have a .223 bolt rifle I use alot and the AR tends to stay home quite a bit. Basically I guess I just like a variety of calibers for different hunting situations and I don't see much sense in having a rifle that just sits there all day every day. I've read up on it quite a bit but I don't know if swapping a barrel to shoot a bigger bullet is worth it. I don't know if I actually will get one as of now but I figure maybe someone will help persuade me to get one or leave it like it is.

One reason my AR stays home more times than not is because it's not as accurate is a big part of it. Another reason is because it won't shoot the bullets I like. If I'm going to have two of something I'd like to shoot the same bullets in either one instead of having to fiddle fart around with buying every bullet weight known to man. Would the 6x45 be considerably more accurate?

I'd say build it. I'm like you, I like variety.

I built a 6.5 Grendel at it goes with me 90% of the time

6x45 is a great choice for barrel swap only. Will increase ballistic performance in an AR for hunting. Very easy to reload with plentiful brass.

I'm following because I've considered the 6x45 myself.

Almost all I hunt with (suppressed as well). It will stack shots, hit hard enough for anything in Texas and give quick followups for hitting multiple hogs. Killed 2 does with headshots this weekend.

Now 2 of the other people at the lease are looking at getting one.

Just finished building one. I have not shot it but I have loaded same rounds. Got a Liberty barrel w\flutes in 20". Just waiting on rings to mount the scope! I think it will be a great low recoil ( watch a few videos) medium range fun rifle.

Thanks for the info so far y'all. The reason I got to thinking I need one more than any other reason is the way my AR functions. It's a 1:9 twist and wouldn't shoot anything but 45 grain bullets or lighter. When I shot 55 grain bullets it never once acted up on me. After switching it would short stroke all the time. I have checked the gas block,changed magazines,checked buffer tube spring,cleaned the bolt and every other part of the gun several times. I honestly think the bullets I'm using both factory and reloads are causing it to malfunction. If it's not reliable with anything I shoot in it I don't need it. I had it do that for the first time during a coyote calling tournament. I called it everything but a rifle that day.

I have been reading up on the 6x45 as well, and like what I've seen, but I think I'm still going to build my AR as a .223. The one negative that stood out to me was having to hand load every single round you want to shoot out of it.

I do handload for .223 already, but I don't HAVE to if I just want to let friends plink with it or take it on a prairie dog hunt, etc.

I think a 1:7 twist .223 that will shoot a 75 gr AMAX or 70 gr TSX is still the best use of the case IMO.

I thought about that too but I have a box of .223 brass that I could run through a die and resize them. It would be a little time consuming is all. I think between me and my grandpa we could have alot of brass resized and loaded in no time.

I planned on using this for hogs and coyotes. My biggest trouble would finding a load that doesn't completely destroy a coyotes fur. Everything I shoot does alot of damage on the inside and leaves little holes on the outside. I'm thinking if I do get one my go to bullet will be an 87 grain Ballistic Tip.
