The mainstream media hates guns. So you won’t find pro-firearm content on NBC, CBS, CNN, or ABC. Thankfully we have independent cable networks such as the Outdoor Channel. And Wednesday nights are a visual feast for shooting sports enthusiasts.
On Wednesday nights, from 7:30 to 11:30 pm, the Outdoor Channel delivers an entire evening of great gun programming. You can watch FIVE different shows: American Rifleman, Guns & Ammo, GunnyTime, Shooting USA, and Shootout Lane. Here are some popular samples from these shows:
Shooting USA — Understanding Parallax in Scopes This Shooting USA Pro Tip defines parallax and explains how to adjust your scope.
Guns & Ammo TV — Hornady Bullets, Nikon Black Force Scopes, Suppressors 101 This episode reviews multiple products — bullets, optics, and suppressors.
American Rifleman — The Guns of The Vietnam War, Part 3 Major John L. Plaster discusses Marine snipers in Vietnam and their rifles.

Each week, Brownells releases a new product video. This week’s review spotlights Hornady match bullets and factory ammo of interest to PRS and tactical shooters. Hornady’s ELD Match ammunition is now offered in the popular 6.5 Creedmoor and 6mm Creedmoor chamberings, along with .223 Rem, 6.5 Grendel, 260 Rem, .308 Win, .30-06, .300 Win Mag, and .338 Lapua Mag. This ammo is loaded with Hornady’s ELD Match bullets which feature heat-resistant tips. The ELD bullet line offers impressive BCs at prices that are quite a bit more affordable than some other match bullets. For example, a 100-ct box of 130gr 6.5mm ELD Match bullets is $32.46 at Midsouth.
For 6.5 Creedmoor shooters, three bullet weights will be offered in factory-loaded 6.5 Creedmoor ELD Match ammo: 120 grain (SKU: 81491), 140 grain (SKU: 81500), and 147 grain (SKU: 81501). Hornady’s 6mm Creedmoor ELD Match ammo is offered in one weight, 108 grain (SKU: 81391).
The 6.5 Creedmoor and 6mm Creedmoor chamberings are very popular with PRS competitors. These cartridge types offer excellent accuracy, and a good ballistics with moderate recoil. Many factory rifles, such as the impressive new Tikka T3X A1, are offered in the 6.5mm chambering.
This video also features Hornady’s new Black Ammunition designed for gas guns. Offerings include 5.45x39mm, 6.5 Grendel, 6.8 SPC, 300 AAC BLK, 450 Bushmaster, and .308 Win. The 6.5 Grendel ammo attracted our attention. That chambering is inherently accurate and could be used successfully in an XTC match rifle or in the new PRS Gas Gun Series.

Sierra’s new 110gr 6mm MatchKing is so new you won’t even find it on Sierra’s website. But MidwayUSA has it listed as “coming soon”. This new bullet, optimized for a 1:7″-twist barrel, promises class-leading ballistics. The listed G1 Ballistic Coefficient (BC) is an impressive 0.617 (sorry, no G7 BC has been stated). That’s 12.8% higher than the 0.547 G1 BC Sierra claims for its older 107gr MatchKing. That’s a very significant improvement. We attribute the reduced drag of the new 110-grainer to an improved hybrid-ogive bullet shape along with much smaller meplats. Sierra has not yet confirmed that it is pointing the meplats of the new 6mm 110s at the factory, but we expect that may be the case. In this respect the 110-grainers could be like Sierra’s excellent 183gr 7mm MatchKings, which come with tight, pointed tips right out of the box.
G1 vs. G7 and Listed BCs vs. Tested BCs — What You Need to Know
Manufacturer-listed G1 Ballistic Coefficients of 6mm Match Bullets
If you look at the table above you’ll see that Sierra’s claimed 0.617 G1 BC for the new 110gr MK is higher than the 0.536 Berger lists for its 105gr 6mm Hybrid and higher than the 0.536 Hornady lists for the new 108gr 6mm ELD Bullet. We do think Sierra’s 110-grainer will prove to have the highest BC of the bunch, based on recent comparison tests by Sierra.
Let’s explain… Sierra lists a 0.547 G1 BC for its 107-grain MatchKing. Sierra tells us that the the .547 listed BC is for the current lots of 107-grainers which are pointed by Sierra. Sierra’s Matt Reams states that the new 110-grainers definitely have less drag than the current Sierra 107gr MKs or Berger 105gr Hybrids: “We have shot the pointed 107s side by side (raced) in our 300-meter range next to the [Berger] 105s and our pointed 107s had a higher BC between those two lots. In the comparison we did, our lot of new pointed 107s had a slightly higher BC than the [Berger] 105s. The 110s are significantly higher than both.”
In the real world, Sierra’s new 110gr 6mm MatchKing may not have as big an edge over the competition as it seems from Sierra’s claimed 0.617 G1 BC. (The G7 numbers may be closer.) Nonetheless, we do expect that Sierra’s new 110-grainer will be very competitive, and may actually have best-in-class BC. And if the new 110gr SMKs come “tipped” from the factory that will be a very good thing.
Anybody currently shooting a heavy 6mm bullet in competition should look at the new 110gr MatchKing when it becomes available. It could prove to be a winner. NOTE However — Sierra recommends a true 1:7″-twist barrel to stabilize the new 110-grainers.

Nosler recently introduced a new series of high-BC bullets with factory-closed meplats. Bryan Litz’s team at Applied Ballistics is now testing these new Reduced Drag Factor (RDF) projectiles to determine their performance — and specifically to see if the BCs are as high as claimed. Nosler bullet testing is underway this week and Litz hopes to bring the results to the Applied Ballistics Seminar in North Carolina later this week (November 3-4, 2016).
Applied Ballistics Seminar Fall 2016: November 3 – 4, 2016 – Caraway Conference Center
4756 Caraway Mountain Road Sophia, NC 27350; Phone: (336) 629-2374. Seminar Sign-Up.
Bryan notes: “If you live in the Southeast region, this is the last seminar for you for at least a year, possibly longer. We will most likely do the next seminars in regions not yet visited.”
Applied Ballistics Library Update
Bryan Litz is hard at work testing new projectiles: “We are currently in the middle of testing all these new offerings that have recently come out. In fact, the lab is up and running today, with some of the new Nosler RDFs going down range. Bullet measurements have been taken with our state-of-the-art digital comparator which is accurate to within 0.0001″. For example, shown below are the measured dimensions for the new Nosler RDF .308 175 grain projectile. For these new bullets, we will not only have complete BC measurements accurate to ± 1%, but we will have Custom Drag Models (CDMs) coming as well.”
New Data Coming Soon
Bryan hopes to present the new Nosler data at the Seminar this week in North Carolina. In addition, Bryan is developing information for the Hornady ELD bullets, G9 Competition Series solid bullets, some new Sierras, and some other projectiles not currently in the library: “Once we complete testing on all these new offerings, we will then compile the library for the next library update (which will be done across all platforms). We want to make sure that none of these new offerings are left out. For those who want to see some of the early results, come join us at this final seminar of 2016!”
Custom Drag Models
Applied Ballistics has been providing custom drag models for use in trajectory prediction for the past several years. Custom Drag Models (CDMs) for bullets are a more refined way of modeling drag for bullets because you’re not referencing a standard like G1 or G7, rather you’re using the actual measured drag of a specific bullet in a ballistic solver. This results in more accurate trajectory predictions, especially through transonic.
