Big Bore ARs designed by an Alaskan gunmaker
      #255271 - 16/10/14 03:52 PM

Not what we usually look at over here, but the fact is that ARs are becoming increasingly popular for hunting in the US. And, I do think that the wood stocked ARs built by this firm in particular, are really nice.

As nice as some of these are, I just can't see them as serious hunting rifles.

Hunting bear in Alaska with a semi-auto? Wouldn't freezing of the action and/or parts be a real problem?

Several years ago, a guy was converting Garands into 458 - I mean a few people have done it but he was in business converting them. I think he stopped but I'm not sure what happened.

How about this - a semi-auto 505Gibbs:

Not all that practical a DG hunting rifle though.

from a technical point o view such things are interesting
its allways thrilling for me to get the maximum out of a given action but there are some prejusdices against rotten plastic on guns in me and the AR 15 was the mother of this crap idea.
like the .50 Beowulf because it was just this - the maximum in the ar 15 - but dont wish to have a AR. think about converting a bloody Ruger Mini 30 because it looks like something the good taste police allow but there are to many projects here and I will never find the time.

Well bear hunting is not as dangerous and man-hunting, and our military uses Auto-loaders for that. So does every other military on earth.

Most of the dogma of how reliable a double rifle is came from writings of 85-150 years ago. And at that time doubles were the most reliable hunting arm available. But I would point out a fact here;
Doubles were reliable in the hunting field BECAUSE if and when they broke you still could hunt using the other barrel. It was like having 2 rifles. So in that knowledge we must define the word “reliable”. 100 years ago “reliable” seemed to mean a weapon you could still hunt with even if it broke. Today “reliable” seems to mean a weapon that doesn’t ever break.

I hunt with a flintlock much of the time. From a standpoint of use and abuse, it's probably the least reliable gun I could use. (Matchlocks and wheel locks would be even less reliable, but I have not hunting with them) So I am not one that worships at the feet of 100% reliability when it comes to hunting, but as a gunsmith and as a former military man I do understand the issue very well.

When we look to the M-98 Mauser and its copies (with or without some modifications) we find a rifle that truly is more reliable then the double rifle. That bit of news seems to drive a lot of double rifle fans crazy but it is none the less true. If you think not we should look at the “test to destruction” that has been done of various rifles and even on handguns.
The criteria is pretty simple.
Fire the weapon in either lab conditions or field conditions until something causes it to fail in a way that requires parts to be worked on or replaced. This usually doesn’t include the barrel, the failure of which is judged on its ability to shoot accurately, not just to shoot bullets. Bore erosion is a function of the cartridge fired, not the type of rifle it’s screwed into.

Many controlled feed bolt actions have gone over 1,000,000+ rounds. In many cases good bolt actions have not failed before the test ran out of ammo. I have never known a class of double rifles or shotguns to be able to boast of that kind of reliability.

So coming back to the original subject, we need to look at the current autos that are being discussed. The AR platform.
It’s pretty common to see them go through many many thousands of rounds before they jam. When they do jam they usually can be cleared in about the same amount of time as you can reload a double. I work on them a lot in my shop and I will say that they are NOT as reliable as a good controlled feed bolt action, but they are not bad enough to make me reject them as a hunting weapon. They may someday attain to the reliability of the AK platform which is probably the most reliable auto rifle ever made. The regularly DO go thought several barrels with no jams at all. I still doubt that an AK is as reliable as a properly built Mauser system or M-70 Winchester, but I would not say dogmatically that I know it. To be able to say that with certainty I would have to have 5 rifles of each type and enough ammo to shoot them all to a failure (and enough years left in my lifetime to do that test, which I do not think could be done quickly).

To complete that test I believe I would have to fire many millions of rounds to get an average. Then I might be able to say the Average M-70 or M98 is more reliable than the average AK or visa-versa.

What I can say right now and right here is that the average M98 or M-70 is going to be just fine for hunting for the average man today.
I can also say that for any well build AR or AK.
Heck I would not feel a bit under armed hunting big bears with my old WW2 M-1.

In good examples, autos are just fine for hunting.
In bad examples (of which we do have many) no rifle is just fine.

I think you are completly right however if we talk about reliable semi auto rifles today we have rifles for the original military cartridges in mind. there can be no doubt that a lot of money was used since WW 2 to make such auto rifles so reliable as we find it now.
but this is about big bore ARs and they use cartridges the action was not build arround. this cartridges are sometimes semi wildcats and handloading only rounds and I dont believe they working smooth as the original caliber in such automatic rifles.

I have used the AR platform in a number of situations, including the one it was designed for as well as for hunting in Alaska, am in complete agreement with szihn.

Still no specific answer to this question. In a freezing Alsakan environment.

I wonder regarding the comments about the reliability of semi-autos? Why then do they need so constant and consistent cleaning to continue to operate well? ie in a military environment, isn't the failure to maintain and keep the s/a clean and serviced a real problem if it is not done regularly?

I've never had this problem with a Mauser 98 or a double rifle. Other than a wipe down, or cleaning the bore which is more for maintaining the life of the bore than keeping the firearm functional.

John,

I'll take a shot at answering that question. Not all, but the majority of our seasons occur when freezing is not too much of an issue. A few notable exceptions would be musk ox hunts, late season caribou and some of the late moose hunts.

Of course there are the fur callers and wolf hunters that hunt during the coldest part of the year. Interestingly, the AR platforms are surprisingly popular with the guys, and gals, that fur hunt through the winter. Many good dry lubes exist that work well on an auto loader during the worst of conditions. And honestly, the AR platform is really a pretty dependable system, no matter what weather they find themselves in. They do need to be kept clean but then the same applies to any rifle or shotgun.

Are they as reliable as a bolt or a double? I cannot answer that. I have not had the level of experience that Phil has with the AR but I've always had good luck with them. I can say they are very dependable in my limited experience and I would not hesitate to hunt with one in the most extreme conditions Alaska has to offer.

Mart

The main drawback of any semi auto gas gun is the consistency of the ammo. If your ammo is all over the place with pressures they are not reliable. Think of it as "regulating" in another sense. I've never used my AR on anything more dangerous tha a coyote but the fact is they do work. Again, I can't speak for freezing conditions but maybe I'll dunk it in a tank and toss it in the freezer just to see? I'm curious also.

For whatever it's worth to this conversation mine has worked fine from ten below zero F to 110 here in the high desert.

I like my ARs, one of which is a match rifle. They are good for many things. However, while in the woods it just doesn't seem right to carry one. I'm not a tactical Barbie so I'll take my HVA 146 long before my AR. 😁
