Rifle Scope Brightness

BY Herschel Smith
18 hours, 20 minutes ago

Busting the myths.

Riflescope brightness is not as big a deal as advertising makes it out to be.

Differences in brightness from scope to scope are often undetectable to users.

Some features credited with brightness don’t even contribute.

Some high-end scopes aren’t as bright as some costing half that.

Maintaining a sharp image is as important as raw brightness. A sharp image at any brightness level looks “brighter” than a softly focused image. Resolution is a critical ingredient for making images seen through a scope appear brighter.

As for the wider main tube contributing to brightness, forget it. Doesn’t work that way. Regardless how much light enters the objective “window.” The higher the magnification, the less light that gets out. The amount of light that exits the scope at the eyepiece depends on the power level. Both objective lens and magnification work together to create the beam of light that exits the eyepiece. It is called the Exit Pupil (EP.) You can see it by holding a scope at arms length and pointed it at a bright surface. The little circle of light you see in the eyepiece lens is the EP. If you have a variable power scope, turn the power ring and watch the EP enlarge and shrink as powers goes down and up. The lower the power, the larger the EP and the more light that exits the scope.

While EP matters, extremely large EP does not because its effectiveness is limited by our own pupils. The human pupil opens (dilates) to about 7mm max. But this doesn’t happen until it’s nearly dark. In full daylight our pupils shrink to about 2.5mm. On cloudy days they might be opened to around 4mm. Place a 5mm diameter beam of light in front of your 4mm pupil and the extra 1mm rim just bounces off your iris. So why bother with a 50mm objective?

The magic hour for hunting is often the last few minutes of legal shooting light a half hour or more after sunset. Our pupils might then dilate to 6mm. They could use all of the 5mm EP and 1mm more. So step up to a big 56mm objective and what do you get? A 5.6mm EP. Not quite the 6mm you could fully use. You’ll need a 60mm objective at 10X to get the full 6mm EP. And if you want maximum brightness at the last minute or two of legal shooting light, you might need a 7mm EP scope. To get that, of course, you’d need a 70mm objective at 10X.

I’m not enough of a precision shooter, especially in dim light conditions, to nay say his observations.  Hunters can weigh in on this.  The most expensive scope I have costs around $600.

I’ve seen other interviews on this incident, but I learn something every time.

Small Caliber Shootoff

BY Herschel Smith
5 days, 18 hours ago

Why anyone would want to penetrate cinder blocks with small bore ammunition I don’t know, but for no other reason than interest, here it is.

I’ve always thought that 22LR was a little underpowered for a varmint round.  I’m not sure I’d keep the 5.7X28 by my bed either.  I prefer PD ammunition because of things like walls, people, and neighbors.

Paul Harrell On The Rock Island Armory 1911

He seems to think it’s okay, whereas for me, being unable to shoot anything I want to put in it is a deal-breaker for me.

He also seems to like Colt, whereas I prefer my Dan Wesson and Smith & Wesson 1911s.  I’ve never had a single malfunction with either of them, and neither has had a hiccup of any sort regardless of what ammunition I feed it (including and up to 450 SMC).

I don’t do FTF/FTE drills with my 1911s because I’ve never had a failure in many thousands of rounds.  But as always, I learn something from Paul (watch his demonstration of the safety feature on the Colt that isn’t there with the RIA, another deal-breaker for me).

What Guns Are The New Owners Buying?

BY Herschel Smith
5 days, 18 hours ago

Vice quotes David Codrea on the rush to purchase guns.  It’s interesting to see what they’re buying.  As for MSRs, here’s the list.

1. Ruger AR-556
2. Smith & Wesson M&P Sport II
3. Smith & Wesson M&P15
4. Springfield Saint
5. Kel-Tec Sub-2000

The real telling statistic is shotguns.

1. IWI TS12
2. Benelli M4 Tactical
3. Armscor/Rock Island Armory VR80
4. Franchi Affinity
5. Kalashnikov USA KS-12

One legitimate bird gun in the bunch.  You think this says something about what people are thinking and why they’re buying?

Never Put Your Thumb Near The Forcing Cone Of A Revolver When Shooting

Gun Sales

1 week ago

From NYT.

It would be an interesting thing to integrate the area under the curve, but with the spikes that would involve use of the trapezoidal rule, or else very small step functions.  I just don’t want to invest the time.

But suffice it to say, this is a lot.  I assume this also involves use of the NICS, and for states that don’t use it (like N.C. where a CHP suffices in lieu of the NICS), that will underestimate the total number of sales, by not a trivial amount.

New CZ 1012 Auto-loading Shotgun

BY Herschel Smith
1 week ago

The CZ 1012 line of gas-less semi-automatic shotguns is not only new to the company but fairly new to the market at such a reasonable price point, with MSRP on our test CZ 1012 All-Weather set at only $690.

Rather than cycling the action using dirty gases, CZ uses a spring within the bolt assembly to harness energy during the shotgun’s recoil motion, and then essentially re-uses this energy a split second later to both rotate and unlock the twin lugs from the barrel extension. This withdraws the spent shell and feeds the next round.

While the majority of semi-automatic shotguns are cycled with the gases generated through the gas system, the 1012 takes a page brought to popularity by Benelli and their Inertia Drive. Inertia scatterguns have been around for years, but that technology generally comes at a much higher cost.

[ … ]

If you’re still thinking the system may be too good to be true, especially for the price, the proof is in the pudding—or in this case—in the Guinness Book of World Records. For reference, the new 1012 action was the one used by competitive shooter David Miller and his hand-selection team of four youngsters to break the Guinness world record.

Together, they fired 20,425 Aguila shotguns shells through nine guns over 12 hours. They smashed the previous record by busting 14,167 clays, with one shooter using the same shotgun for the span of the event. The others only switched once.

I really like the cammo gun they’ve built.  If I heard her correctly, she said the patent on the intertial system expired and CZ apparently took advantage of that.

It’s nice to see a moderately priced auto-loader.  This gun might be in my plans for the future.

Paul Harrell Versus Gun Nuts Media

BY Herschel Smith
1 week, 6 days ago

Watch all of this video (it’s long) or my comments will make no sense at all.

Allow me to weigh in a bit.  I’ve never seen or heard of this guy (“Caleb” from Gun Nuts Media – I have no idea if that’s his real name or a nom de guerre).  I have visited his site once as you’ll see below, and I’ll never visit again.

He impresses me as a spoiled little boy, a narcissist, a child who was never spanked, a liar, and a drama queen who writes click bait for his web site and soap operas for his YouTube channel.  He’s much too emotional for my tastes.

If he was never spanked as a child, he certainly was by Paul in this video.  He deserved it.  I agree with everything Paul said, but even if I had not, there’s a moral issue at stake here.  It comes from Leviticus 19:32.  “Caleb,” if you need help with exegesis of that, write me a note.

On the issue of revolvers and “hitting” or slapping the ejector rod, I’ve done that as long as I’ve been shooting revolvers.  I’ve never had a problem.  The only problem I’ve ever had was with a S&W R8 revolver.

It’s tolerances are tight, and it’s very accurate.  I’m sure those are related things.  I could have taken the time to ream the cylinder a bit and gotten better performance, but there would still be the issue of the forcing cone being so tight against the cylinder.

Within 50 rounds without fail, shooting high power .357 magnum ammunition which of course runs very hot, the metal would expand and cause either (a) the brass to fail to come out of the cylinder (which necessitated me striking the ejector rod pretty hard), or (b) the cylinder seizing against the forcing cone until the gun cooled down.

I dumped the gun.  It was a wonderful gun, but I just wanted to shoot more than it would allow without heating up too much.  Every other wheel gun I’ve ever shot only had that problem to a much less degree, this one to a much greater degree.

So if you needed any more information about Gun Nuts Media, here is something they have to say about what should be your own choice.

Basically, it’s 2019, and if you aren’t shooting 9mm as a primary pistol cartridge, you need to re-evaluate your life choices. It’s now an undisptued fact that modern 9mm ammo can give ballistic performance on par with 40 S&W, 45 Auto, and pretty much every other handgun cartridge.

“Re-evaluate your life choices.”  Being a bit dramatic, are we?  If you shoot anything other than 9mm you need to “re-evaluate your life choices.”

Okay, first of all, it’s simply not true.  Oh, it may be close for two-legged threats, but it’s certainly not true for four-legged threats.  Moreover, if someone happens to shoot .45 ACP or .40 S&W better than 9mm, or .38 Spl better, they should be allowed to shoot whatever works for them without internet know-it-alls telling them not to.  Some rounds push, some rounds snap and cause more pronounced muzzle flip.

Either way, I don’t think there’s a nickel’s worth of difference between someone telling you that you shouldn’t be allowed to have such-and-such gun, and someone telling you that you should shoot such-and-such a gun because I say so.  Each is a different form of collectivism.  I can’t stand collectivists.  Mind your own business.

And “Caleb,” grow up, little boy, and quit being a drama queen.  Maybe when you do, you can be like Paul.
