Default Changing AR barrels/cartridges.



Advertise Here

Sitting out waiting for the deer to walk by, I had brought the .300BO with me.

The handful of does that I saw were at the limit of my ability with the BO, and not legal for me, too bad the kids weren't along.

The three moose that walked by also gave me a moment of concern.

And as much as I like the BO cartridge, the heavy barrel is heavy compared to the .223/M4 barrel of the youngest. So eventually a lighter barrel will be acquired.

But until then, I will be swapping the BO out for something with more range and oomph. And yes I do have other choices but the AR is enough lighter, (and lower recoil) that it has become the best option a lot of the time.

So right now, I am looking at the 6.8 and the 6.5 Grendel.
Any other options that I am missing that fit the AR and are good to 300-400y?

6.5 Grendel is the hot ticket and the solution to your woes! You could shoot a moose with it but the shot placement and bullet choice will be critical for most shooters. I would prefer something more substantual in that case. Its a very flat shooting and modest recoiling round with a lot of good bullets out there for it. Even wolf is making steel cased ammo for it in the 6-7 dollar a 20 round box range. Make sure you get one with the type II bolt on your BCG.

The 350 Legend might be the cat's meow for short range woods hunting. Winchester claims it equals the old 35 Remington which was a standard woods gun for years and years.

OP

The Grendel is what you seek, but don’t go Moose hunting with it. 120gr-130gr controlled expansion bullets will not carry enough energy after 50 yards to reliable penetrate and kill a 1000 lb moose.

The Grendel was on the short list for several reasons, picking up a 6.5 Swede has been a consideration. But the 6.8 also has its points as I already load for the .270 Win.

I don't mind adding another caliber of it makes sense.

As for moose hunting, WY hands out 3 tags a year, and to be in the consideration list you have to have 8 preference points, so if I started applying today, I might get a tag when I am 75. Pass.

Basically I want to maximize the package, practical power and range.

Here's hoping that there are some good post-Christmas sales.

It's just me but I'd consider a more appropriate rifle.

Indeed. With AR-10s only running $700 it would be fairly easy to pick one up and keep the same style of weapon but have it in a true high power hunting caliber.

Ok? What rifle is appropriate?

In this case, I already have the AR, its light and doesn't beat me up.
I can assemble a myself, only the cost of a barrel, bolt head and ammunition (reloading stuff), some of us are on a budget. No paperwork or the $500+ for a new gun, and how much gun do you need for a deer or antelope?

Is a .338 Mag enough? I just passed on one of those.
Do I need a Fudd gun? I have a couple, they weigh more than I want to deal with unless I am after elk.

.350 Legend is about $280 , BCG, CH, MLOK handguard. Just pin it on and go.
16”

18”.
https://www.bearcreekarsenal.com/bca...lok-split-rail

6.5 Grendel is probably better at over 200 meters. BCA is $220, but totally out of stock. PSA has some, but they cost more, as do most other budget places.

The point is, for the cost of the conversion you are most of the way to the price of a new gun, say something .308 based. Iíve was in the same place as you, and considering the same things, but the math was not on the side of a caliber change.

You donít need much gun for deer, but the whole premise of your post is that you donít have enough gun....

On the right day, he can change to 6.5 Grendel for $220, and have it shipped to his house.

I know you can buy a Savage Axis for close to that...but he wants an AR based option.

All of that said, I kind of agree with you about the need for more oomph at the 400 yard range, and the AR-15 may not provide enough of that, unless he spends “more” money.

Well, cost kind of depends on what you have already.

You have the cost of new mags, new reloading gear if you reload, new ammo, add that all up and you get close to the cost of a PSA AR-10 pretty quickly.

Especially from a prepping point of view there are very real logistics costs that come with adding a caliber beyond just the price of a new upper.

For most common problems, I can handle it with a .25-06, or a .270, or a .30-06.

No need to get in a wad, dude. Many of us are on budgets. My options didn't just happen overnight. They came about over 50+ years.

Look at the Grendel’s ballistic charts for a 16” barrel and you’ll see the sweet spot and where it starts to run of of punching power.

Actually the biggest reason was to get more punch and range out of the AR that I have. A friend wants the BO barrel so that covers part of the cost of the new barrel. I already have two good bolt guns in .308 and 8mm, but there are days when the back and other aching parts say those are too heavy, in recoil and weight.

Not adding a new upper, just a barrel, bolt head and mags. Ammo I can get to along the way. And if I go 6.8, the bullets can be shared with the kids .270.

Nothing in a wad, and I have used a bunch of options over the years. Tried a nice Aero Precision .308, it was just too much for me on a bad day. I believe that the term is impingement.
And having been hunting nearly 40 years, like you, I have a fair idea what works.
Having to accept that I ain't 25 anymore and have to face my limitations.

So for a multitude of reasons, it's a new barrel on my existing gun.

I don’t get the idea of swapping a barrel. An upper costs $30-$50.
Unless you are literally stripping your .300 barrel off, so you have an empty upper?

Which I also don’t get. I have a .300 barrel coming tomorrow, it cost $54.

But...here’s your 6.5 G barrels. I have a 5.56 from these guys, it groups.

If you have to have it in at-15 and want deer I would go with the 6.5 Grendel. If you want moose I would go with something like the 450 BM, 458 or 500. I have a 450 BM and with 275 grain xpb for deer and it is way overkill. Someone on the 450bushmaster forum was asking for a bison load and the 275 xpb/tsx was recommended. The downfall is 250 yards is about the max. I would only do 200 yards.

If not a tons of used lever actions. Or is you want an ar them 6.5 creedmoor in at-10 style rifle would work for either animal at the distances you want.
