Jason McCann here with Mountain Tactical Company. Hey, I want to talk to you today about accuracy, specifically about accuracy of rifles that we've built. And it's a little controversial, but I don't guarantee the accuracy of any rifle I build. I will guarantee the machining all day long. But I will not guarantee the accuracy because every shooter is different. You just might have a shooter who just doesn't know how to shoot, and he thinks he can buy accuracy. Whereas you guys have been shooting for a while, now the only thing that can guarantee accuracy is trigger time. 

So I'm going to show you exactly what I mean with a rifle that we built. There is an interesting story behind this rifle that I'll get into a little later, but the guy says it doesn't shoot. It shoots three quarter MLA. He says that's not good enough [00:01:00] for him. And so I told him to send 20 rounds of ammo, so we could test it and bring everything back. And so he brought it all back here, and let me show you what we found. 

Okay. So, multiple things affect accuracy. And I personally as long as I know the machining of the rifle is done well, which were Tikka Shooters, the fins do an excellent job of machining. Every once in a while they send a rifle out that doesn't shoot, but for the most part, the rifles are bomb proof. This particular rifle I borescope the chamber. I test fired it five rounds into a nice little bug hole prior to sending it to the customer. So I know the machining solid. 

So the first place I'm going to start is ammo. Now if your ammo is not concentric, which means that the bullet’s not perfectly round to the case, and the case is not perfectly round to the bore, the bullet’s going to be in the chamber cricket, which is obviously an issue. So Sinclair, being the precision minded people that they are, [00:02:00] created this handy little gauge to help guys determine if their rounds are concentric. 

Now, typically speaking, I mean, this is just a general rule, and it depends on the level of accuracy you're going for. Obviously, zero run out is perfect. In the real world, you're not going to get your run out. But if you can get two or 3,000s, that is acceptable for most applications. And so, this, what we do here is we rotate this, and then we watch this needle. So watch that needle. So we're down to call the 40. This is about 8,000s out of concentricity. This round’s never going to shoot accurately. I might shoot 7 MOA, but it's not going to show the potential of the rifle. Boom, here we go. Let's try this again.

[00:03:00] This one's almost 10,000 static concentricity. Swing’s not as bad. This one we're looking at about sixish, thousands out of concentricity. So in there, may not shoot. So here's a just grab this out of our stock stuff that we've reloaded here on the shop with our own dyes. And looking at okay, down. We're at 3,000s out of concentricity. So what causes the bullet to be out of concentricity? 

Well, you could have a bad jacket on the bullet [00:04:00] where you have a fixed spot on there. And I measured all these prior to shooting this video. And his issue is all his necks are out of concentricity, which means his reloading dyes are bad. And so I'll adjust this here real quick show you how this works. You slide this so you can use multiple cartridges on here, and I'm going to just lock this down here, and I'm going to show you how concentric this neck is. So here's our needle up here. Barely moving about one-and-a-half. I skipped it there.

You can't buy accuracy. You got to have trigger time...

Let's get a better measurement here. I have one to one-and-a-half. So it's between one and one-and-a-half thousands out of concentricity, and this is with dyes proven. We use the [00:05:00] Redding Competition Dies. And when this round, I mean, this is what I'd expect to see out of a non turn neck is usually one to 2,000s concentricity. If we turn these necks, we can get them dead nuts perfect. So let's go out shoot this rifle and see what does this all mean.

All right. Well, here we are out here with the rifle. I brought some of the loaded ammo that we have loaded at the shop, some of the customers loaded ammo that we saw that was out of concentricity. And I brought some factory ammo as well so we can compare accuracy of everything. So I just threw a scope on here that we had at the shop. I'm going to get it cited in, and then we will test it. See why this rifle’s not shooting.

[00:07:00] Let's see what we got to make our adjustment. I'm going to keep shooting, and then I'm going to tell you a little bit more about this particular rifle and about this particular customer. I don't like talking about customers individually, especially ones that are having issues. But as I elaborate, I think you'll understand why I have no issues explaining the details of this particular customer. 

[00:08:00] So I'm going to keep shooting. And then, I think, I'm going to take this, I don't even know what velocity we're getting or anything. But I think I'm going to take some of the customers own ammo and I'm going to hit our thousand yard gong with it. This rifle shoots great. This is, I mean, as you can see it's not moving. It’s stable. This has all of the best of Mountain Tactical in it, and it's performing downrange as such. So I'm going to keep shooting. I won't bore you guys at this point. And I'll go into specifics about the build and about the customer after I prove my point that much more. 

[00:09:00] All right. Well, you can tell I was rushing a bit. We have all five rounds up here. 7m away. It's when the cows were moving in, so definitely 7m away there. Got half MOA here within about, that's all right, not bothering any girls. Customer’s ammunition that was out of concentricity back in the shop, three to quarters MOA here shot, two three shot groups here both just kind of ragged holes. Now assuming I did that and then I adjusted my scope and that one, so that's a three shot group adjusting my scope, and then right there, but the ammo that we load in house, that's five rounds. 

So that's the difference between [00:10:00] having concentric ammo, loading, reloading, having good reloading practices. This whole rifle has me so frustrated. I'm sorry. The five rounds into that bug hole versus three quarters MOA is still a decent group, but he's obviously having issues with his dyes. Let's turn around. I'm going to take one of these rounds, and I'm going to ring our thousand yard Gong. So let's do that, and then I'll fill in on the rest of this. 

All right. So I'm going to start at the 500 yard gong, because I have no idea what the muzzle velocity is with the ammo that Thomas loaded. And I'm going to estimate 2700 feet per second, we are shooting a 26 inch barrel. Loaded that into my shooter app that gives me 9.8 MOA. So we’re cited in at 100 yards. I'm going to shoot that, [00:11:00] verify the dope, and then we'll take it to 1,000. And we're using his ammo that we've already proven is highly out of concentration.

I'm just going to use holdovers in the scope. I'm shooting a Vortex HS LR 6024 x 50. We have the Christmas tree radical in here. Really cool radical. Wait for situations like this. I don't want to rezero the whole scope. [00:12:00] And I just want to verify data. So, all right. Let's see what we got.

Smacked it. Little high. All right. So that was actually 8 MOA according to my Christmas tree. So let's use 8 MOA. We have about one MOA of wind. See what we get here. Still little high [00:13:00] like 7 MOA. Must have these things loaded really hot. Off to the right. Man this ammo that he loaded is crap. 

That's okay. We'll just figure out the dope for the thousand and shoot that. Wind flag’s really going and 1,000. Let's see. I bump that load up to, [00:14:00] all right, edit this. I am going to say, give it 2800 feet per second. We're shooting 140 grain berger hybrid. Let's resolve this for 1,000. 28.7 MOA elevation, six-and-a-half MOA for wind.

All right. Well, let's see what happens. And I am just using hold over. So that makes this [00:15:00] all the more interesting. 

[00:16:00] Well, there we go. We took unknown load data, hit the gong twice. I mean, this rifle, it's just so easy to shoot. Tikkas are exceptionally easy to shoot, but this we have an M24 barrel profile. We turned it down to match the receiver. We have a Remington style recoil lug, our competition bed job all the way through the chamber. We Cerakoted this patriot brown, no, excuse me, federal Brown. We have our 20 MOA elite rail. This is a Manners Composite stock are really nice stock actually. This rifle’s amazing. 

Now, the guy who asked us to build it for them contacted us, says, he's in charge of the Secret Squirrel, [00:17:00] Southeast Sniper Task Force for Department of Homeland Security. And to start out, he seemed very legit. He had all the right lingo. I don't know. As the relationship went on, all of a sudden he's talking about having me fly out there. He'll take me to the farm. And I know some guys have some pretty high security clearances, and they're not even allowed in the farm. So my bullshit meter is going off the charts there. 

We sit on this rifle, and all of a sudden he sends me these emails. He's texting me. He's lightened me up saying this rifle doesn't shoot. Well, as you guys see, we shot all sorts of ammo through this thing, and it shoots just fine. And I mean, shoot, I don't even know the load data. And I was able to ring the gong twice at 1,000 yards. So there's nothing wrong with this rifle. 

And so I told him to send it back plus 20 rounds of his loaded ammunition, [00:18:00] so I could test it. More often than not, it's reloaded ammo that causes problems. It's poor reloading practices. And he sends me a suppressor through the mail illegally, no forums. Well, I have to immediately call the ATF. I'm not willing to risk my license for this guy who supposedly Department of Homeland Security. 

And it was interesting because while I called the ATF, they did some background. This guy doesn't work for Department of Homeland Security. He was a chief on some C130 up in Kodiak, Alaska for the Coast Guard, goes down to the Carolinas, opens up this tactical training school. He then sends me a letter from his Captain Lighten which Captain Lighten come to find out just works in a warehouse, not even a captain. He's a Gunnery Sergeant, works in a warehouse for the Coast Guard and ripping me a new one. 

It's bad enough that he's pretending [00:19:00] to be somebody who's not, but the guy can't shoot, and he's blaming me. It's causing this huge ruckus. He's breaking as many. I mean, it's so many loss, wasting my time. I have spent a total of 16 hours on the phone with government agencies talking about this rifle. It's just ridiculous. 

So anyways, I'm done venting. The rifle, this is awesome. This is an example of what we build as far as custom rifles out of our shop. As you can see, I'm not even the best shooter in the world, and I can make this rifle shoot. I do have very good reloading practices. I will guarantee the machining, on any rifle we build, it's going to be within 210 thousandths of an inch tolerance. Any ammo that I load is dead nuts. I shoot competitions, and I want to remove as many variables as possible. [00:20:00] So the ammunition I'm shooting that I reloaded is dead nuts, and you can see the difference in accuracy from our previous test. 

So, perfect example. You can't buy accuracy. You got to have trigger time. You got to train. And in my opinion, no gunsmith should ever guarantee the accuracy of a rifle they sell, because it's not the rifle. It's the shooter. We can machine it perfectly. We can make everything dead nuts, and the guy just can't shoot.

So anyways, enough of this video. Awesome rifle, dirt bag guy. Hopefully, he gets in trouble for impersonating a Federal officer. You guys have a good one. I'm going to shoot this some more [00:21:00].
