Here’s a “heads up” for our Forum members and site visitors. This evening, we plan to install new software for our SHOOTERS’ FORUM. As a result, the Forum will be offline for approximately 16 hours, starting at about 9:00 pm Central Time on December 27th. The Forum will remain off-line as we transfer all the data (600,000+ messages) to the server running the new Forum software. We anticipate this process will be conclude in the early morning hours of December 28th. If all goes well, we hope to have the Forum re-activated by noon on Monday, December 28th.
The new software gives us improved security and stability, and it should allow the Forum to run faster. In addition, the upgraded software is mobile-friendly so it will automatically adjust to the platform you are using — whether desktop, laptop, tablet, and even smartphone.
Current Forum categories and threads will be preserved, and we will maintain the general layout. But you will see some differences in link/button locations and in user profile screens.
Log-In Procedure (Read Carefully)
You will still be able to use your current Forum name and password. However, some users who changed their display name(s) will have to use their original name or original email address to log-in.
So guys… don’t freak out if you cannot access the SHOOTERS’ FORUM tonight. God willing, everything will be in place within a day. We’ve done a successful test, but there could still be some unanticipated hiccups. This is a MAJOR upgrade. If all goes according to plan, there will simply be a “time out” until mid-day on Monday.

The Coriolis Effect comes into play with extreme long-range shots like this. The rotation of the earth actually moves the target a small distance (in space) during the course of the bullet’s flight. Photo by Dustin Ellermann at Whittington Center Range.
When you’re out at the range, the Earth seems very stable. But it is actually a big sphere zooming through space while spinning around its axis, one complete turn every 24 hours. The rotation of the earth can create problems for extreme long-range shooters. During extended bullet flight times, the rotation of the planet causes an apparent deflection of the bullet path over very long distances. This is the ballistics manifestation of the Coriolis Effect.
Bryan Litz of Applied Ballistics has produced a short video that explains the Coriolis Effect. Bryan notes that Coriolis is “a very subtle effect. People like to make more of it than it is because it seems mysterious.” In most common shooting situations inside 1K, Coriolis is not important. At 1000 yards, the Effect represents less than one click (for most cartridge types). Even well past 1000 yards, in windy conditions, the Coriolis Effect may well be “lost in the noise”. But in very calm conditions, when shooting at extreme ranges, Bryan says you can benefit from adjusting your ballistics solution for Coriolis.
Bryan explains: “The Coriolis Effect… has to do with the spin of the earth. You are basically shooting from one point to another on a rotating sphere, in an inertial reference frame. The consequence of that is that, if the flight time of the bullet gets significantly long, the bullet can have an apparent drift from its intended target. The amount [of apparent drift] is very small — it depends on your latitude and azimuth of fire on the planet.”
Coriolis is a very subtle effect. With typical bullet BCs and velocities, you must get to at least 1000 yards before Coriolis amounts to even one click. Accordingly, Bryan advises: “Coriolis Effect is NOT something to think about on moving targets, it is NOT something to think about in high, uncertain wind environments because there are variables that are dominating your uncertainty picture, and the Coriolis will distract you more than the correction is worth.”
“Where you could think about Coriolis, and have it be a major impact on your hit percentage, is if you are shooting at extended range, at relatively small targets, in low-wind conditions. Where you know your muzzle velocity and BC very well, [and there are] pristine conditions, that’s where you’re going to see Coriolis creep in. You’ll receive more refinement and accuracy in your ballistics solutions if you account for Coriolis on those types of shots. But in most practical long-range shooting situations, Coriolis is NOT important. What IS important is to understand is when you should think about it and when you shouldn’t, i.e. when applying it will matter and when it won’t.”
The Coriolis Effect — General Physics
The Coriolis Effect is the apparent deflection of moving objects when the motion is described relative to a rotating reference frame. The Coriolis force acts in a direction perpendicular to the rotation axis and to the velocity of the body in the rotating frame and is proportional to the object’s speed in the rotating frame.
A commonly encountered rotating reference frame is the Earth. The Coriolis effect is caused by the rotation of the Earth and the inertia of the mass experiencing the effect. Because the Earth completes only one rotation per day, the Coriolis force is quite small, and its effects generally become noticeable only for motions occurring over large distances and long periods of time. This force causes moving objects on the surface of the Earth to be deflected to the right (with respect to the direction of travel) in the Northern Hemisphere and to the left in the Southern Hemisphere. The horizontal deflection effect is greater near the poles and smallest at the equator, since the rate of change in the diameter of the circles of latitude when travelling north or south, increases the closer the object is to the poles.

Holiday Greetings to Our Readers
Merry Christmas and Happy Holidays to all our readers and especially our nearly 30,000 Forum Members. This marks our our 11th Christmas “in business”, and the site is stronger than ever thanks to our members and industry sponsors. AccurateShooter.com (and 6mmBR.com) are now accessed by over 550,000 visitors every month. Part of the reason for that success is the hard work of our volunteer helpers.
Unsung Heroes Deserve Recognition
I want to acknowledge some guys who have really helped out the site. Number one is JayChris, our IT guy — he keeps the servers running smoothly and maintains our Forum. Jay has been working through the holidays on a major Forum upgrade we hope to roll out at year’s end. This is a big undertaking, requiring great technical expertise. Jay deserves our thanks for all his hard work and his dedication… working nights and weekends to keep this big project on schedule. Thanks also go to Jeff Williams, our “Answerman” who fields miscellaneous questions from our readers. We have a great place to test rifles thanks to our good buddy (and designated trigger-puller) Joe Friedrich. Special thanks go to the 6.5 Guys, Ed Mobley and Steve Lawrence, who authored our latest Cartridge Guide, and contributed SHOT Show videos. I also want to recognize our regular contributors, including Vince Bottomley, German S., Jason Baney, Robert Whitley, Tony Chow, Mark LaFevers, and Gavin Gear. And we must acknowledge Boyd Allen and EdLongRange who tirelessly supply story leads for the Daily Bulletin. These guys (and many others) have all contributed much time and effort.
We also want to thank our major sponsors, without whose support the site could not provide the full AccurateShooter.com experience, with an active Forum, an archive of in-depth articles, and fresh content 365 days a year in our Daily Bulletin. We’re grateful to all our sponsors and advertisers. In particular, I want to acknowledge Shiraz Balolia, a great friend of the shooting sports, and a gifted marksman in his own right. Shiraz has provided key support for this site though his companies Bullets.com and Grizzly Industrial.
John Adams and Jerry Tierney Have Left the Range…
I also want to say a word in remembrance of two good men (and talented shooters) who really helped the site. John Adams, one of the site’s first Forum members, and a great supporter of our efforts, passed away just over a year ago. And we lost Jerry Tierney, a champion shooter in many disciplines, just this month. These men both served as mentors to me, and their knowledge (and good fellowship) will be missed. John and Jerry — rest in peace, my friends.
With each passing day, prices are dropping at Midsouth Shooters Supply. Right now Midsouth is running its end-of-year Inventory Closeout Count-Down. This is a very unique sale — now through December 31st the price on Midsouth’s clearance items drops 5% each successive day. So the deals get sweeter and sweeter. But, inventories are limited — if you wait too long you may be out of luck.
Today, four days into the sale, every item on clearance is 25% off. That’s pretty tempting. Remember — the number of clearance items offered is strictly limited. If you see something you like you can watch the price drop 5% each day. But if you procrastinate, the item may get sold. As Midsouth says: “Wait too long and it may be gone”. CLICK HERE for SALE.
Here are some of the best deals we saw this morning (12/24):
What could be more fun than decorating a Christmas tree? Well how about busting Xmas ornaments with a .50 BMG. Boys will be boys, right? This 50 Cal Days of Christmas video features some fantastic slow-motion footage of a Barrett .50 Caliber M82. This bad boy pumps out some serious muzzle flash. Watch carefully at the 1:05 mark and you can see the .50-caliber projectile exit the muzzle brake and spin through the ball of smoke and flame.
The video carries “overkill” to the max, as the shooter uses his big Barrett to blast Christmas ornaments and a snow-globe. To top things off, at the 2:50 mark, the shooter fires the .50 cal at a pyro-equipped gingerbread house. (The gingerbread shot is taken from a standing hold no less!) The results (at 3:22) are impressive — gingerbread house becomes flaming gingerbread pudding.
Shooting Times has released an article entitled “Ten Most Common Reloading Mistakes”. Listed below are the Top Ten mistakes hand-loaders can make, at least according to Shooting Times. What do you think of this list — does it overlook some important items?
Top Ten Reloading Mistakes According to Shooting Times:
1. Cracked Cases — Reloaders need to inspect brass and cull cases with cracks.
2. Dented Cases — Dents or divets can be caused by excess case lube.
3. Excessive Powder Charge — Overcharges (even with the correct powder) can be very dangerous.
4. Primers Not Seated Deep Enough — “High” primers can cause functioning issues.
5. Crushed Primers — Some priming devices can deform primers when seating.
6. Excess Brass Length — Over time, cases stretch. Cases need to be trimmed and sized.
7. Bullets Seated Too Far Out — If the bullet is seated too long you may not even be able to chamber the round. Also, with hunting rounds, bullets should not engage the rifling.
8. Burrs on Case Mouths — Ragged edges on case mouths can actually shave bullet jackets.
9. Excess Crimp — This is a common problem with pistol rounds loaded on progressives. If case lengths are not uniform some cases will get too much crimp, others too little.
10. Inadequate Crimp — This can be an issue with magnum pistol cartridges in revolvers.
Do you agree with this list? We think some important things are missing, such as not adjusting full-length sizing dies properly. This can cause the shoulder to be pushed back too far (or not far enough). Another common mistake is using brass that is worn out, i.e. stretched in the case-head area from multiple cycles of hot loads. We also think the #1 error a reloader can make is using the wrong powder altogether. That can be a fatal mistake. See what happens when you load pistol powder in a rifle.
