Biulding another ar-15 for hunting hogs and cant decide what caliber already have a 5.56 and 300 blackout but i have read they can be lacking at times . I dont want to do a ar10 at this time . What is a good caliber yall would recommend i reload so i can squeeze out the most from it .tia

What you already have is no better or no worst than any other caliber. If you just want to build one just close your eyes and point and what ever you land on build.

300 BO with a 110gr Barnes VORTX will make a hog good and dead real quick. If you're just wanting a new caliber, I have had really good luck with my 6.8 SPC and a 90 gr speer gold dot.

I built a 7.62x39 for hogs. Ammo is cheap and the hogs don’t handle that round very good. Does a heck of a job with the cheap HP ammo. I also killed a few truck loads of hogs with my 223/556. It’s just me but there is nothing about the 300 blackout that peaks my interest.

Yes going to biuld another ar already have
224 valkyrie
5.56 match
300 blackout pistol
Thought about a 300 ham'r or 6.8spc already use a 30cal suppressor on them now

7.62x39 All Day Long.

I have no issues with my .223

I would say either a 6.5 grendel or 6.8 spc. I have both and like them

A 6.5 Grendel is ideal. It’s got better penetration than a 300 blackout and it’s still in a cheaper ar 15 build.

Love my Grendels.

When the hogs really started showing up on the farm I would carry my 223/556. It would kill them but you had to sometimes shoot them multiple times to drop them. I shoot a 55gr. lead core HP and they were cheap so I would shoot till they drop. I decided to build the 6.8spc after some research. It did a really good job on the hogs but the ammo is not cheap. It got expensive to shoot. The cost of the ammo gave me a reason to build the Grendel(you know what I mean). It also did a good job and cheaper FMj ammo could be found but I don’t like shooting an animal with FMJs so good ammo costs were not cheap for the amount I was shooting. That’s when I read about the 7.62x39 and decided to build one. This has been my go to hog(and deer sometimes) rifle ever since. I bought a good supply of lead core HPs for $4 a box and they will flat out a hog on its arse if I do my part. I don’t have the longer range of the other rifles with it but I can still stretch out a good ways as I’ve practiced my hold overs and really learned what this rifle can do. I still carry the 223/556 for larger groups. I’ve been carrying the 350 legend I built to try to kill some with it but have seen any yet. They all will do a good job on the hogs and if ammo costs don’t matter and you want just one AR, my opinion is build a Grendel.

When I was a child we always used a 22 to the ear hole lol. With that being said I'd go with a 450 Bushmaster 👍

458 SOCOM is what I am building for hogs.

i have a 223, 300BO, and 6.5 grendel. I like the 300 BO for hog hunting due to performance in the woods.

223 to the head, makes a hog dead.

Another yes vote for the Grendel. Got the 18” upper from psa for the past season and im sold . Got two bucks one hog and three yotes with it. However my next one will be the 300 hamar check it out better ballistics than the Grendel and all you need is the barrel and I think it uses blackout mags.

I have the 223, Grendel, 300, Bushmaster, and the 22lr. The grendel is my overall favorite but when I'm going after hogs I always grab the 450 Bushmaster myself.

I've been wanting to build one in .308

my favorite is the 762x39. Was using the psak 47 rifle with folding stock and iron sights, due to optics fogging early in the morning in muggy weather. This year i went to psak 47 pistol with sig romeo 5. i use mine for hog dogging, so i like something small and light weight getting in/out truck and walking through the woods in the summer. Ammo is cheap, but very effective. You can also buy a case of ammo to stockpile for a couple hundred dollars.

Check out Bear Creek Arsenal, they had complete rifles for less than 400.00 in several calibers.

6.5 Grendels all the way.

6.8 has been more emphatic on deer and hogs than the Grendel, for me. That’s probably more anecdotal to the bullets/velocities I’ve used in the 6.8 vs what I tried in the 6.5. I just feel that inside 100 it was noticeable. I may bump to 300 HAMR and try it. 223 and the right bullets works for the right shots, as does the Grendel....it’s the after the first shot mayhem that causes problems for some stuff. It’s needing a quick follow up that causes problems with the big kickers. If shooting multiples day/night isn’t your niche, most anything will work from a stand to take a single, stationary hog.....but I’m not claiming any major expertise, either....few get to shoot 500/yr like Bill Wilson, or thousands like Jaeger.

I just replaced my 7.62x39s that were purpose built to hunt deer and hogs with grendels. More than double the range, much better terminal performance due to high sectional density bullets with almost no recoil.

Terminal performance is FAR more about a bullet design, than a headstamp.....if you’re only shooting factory, the 6.5 loads I’ve used weren’t nearly as emphatic at usual hunting ranges, as the factory 6.8 loads. That could be changing, but stuff inside 200 always died faster for the same placement, with 6.8, or even 223 sometimes.

7.62x39

Bought a 300blk as a woods rifle for deer. Killed a 4yr old 165lb 8pt at 90 yards this year. Shot him in the shoulder and he went about 60yards and piled up. shooting Winchester deer season xp in 150 grain

Try sst. They are explosive. I use more robust bullets because I want as much penetration as I can get. Not much difference between 6.8 spc and 6.5 grendel inside 200 yards ballistically or terminally. The difference comes beyond that, 6.8 runs out of steam at 200ish and the 6.5 is just getting started. I used 6.8 spc for a while when they first came out but switched up to 7.62x39 once the ar world figured out how to make one run. Now it's grendel until something better comes along.

Actually, it WAS the bullets available (SST was one of them) and performance UNDER 200 (90% of AR hunting use for me) vs sometimes past 200, which led me to dump the Grendel FOR a 6.8, years back. I do load, but don’t intend to load for ARs for hunting. There may be better stuff now, but until Nosler screwed up the SSA 110 AB, and Fed screwed up the XM68, those two were far better hunting rounds than anything I found over the counter in a 6.5....which was either too explosive, or didn’t expand well at the velocities of a Grendel, especially in smaller deer and hogs. Waiting for shots past 200 might have worked to make the SST useful, but from 0-200 was where the need was. I still may jump to the HAMR, but everything most tout in a Grendel is not as helpful for how/what I hunt with an AR, and having enough emphasis in the act. Just my druthers. The 6.5 creedmoor does some impressive things with some of its bullet/velocity combos. Just never saw that from a Grendel, but maybe I gave up too soon..

Do like my son, get a 458 SOCOM and nothing in the continental U.S. will stand up to it.

We use 6.5 Grendels. We shoot Wolf FMJ that has been pretty cheap til the current panic and now it is hard to find. But it's an inexpensive round for those of us that go through a 1,000 rounds a summer or more.

Sure, my 308 has better knock down but it's way more expensive when someone empties the clip and hits nothing!

Stay away from 765 x39m. They are addictive!! I got a big safe overflowing with guns. 5 of the last 6 I bought are 7.65 x 39. . It is a good caliber for everything from mice to mulemule deer.deer

7.62x39? Never heard or seen a 7.65x39.

Em 7.65 are good for those mulemule deerdeer. Ain't you heard?

This is a first post I can get behind.

My grendel is a sweet tool, amo selection is sparse but Im sold. Ive killed deer hogs and yotes with it.
Check out the 300 Hamar, 30 cal but shoots flatter than a 30/30. all you need is the barrel and mag uses same bolt and everything else as the ar 15.
Def my next build.
