Gun Digest reloading video series Phil Massaro youtube

Gun Digest reloading video series Phil Massaro youtubeDo you have a friend who is getting started in hand-loading? Or would you like a refresher course in some of the more important aspects of reloading? Today’s video showcase provides a wealth of information. In these videos, Philip Massaro, Editor-in-Chief of the Gun Digest Annual, explains the techniques handloaders should employ to create safe and accurate pistol and rifle ammunition. These videos are part of an 11-Video Reloading Series from Gun Digest.

After the intro video, there is a video on case resizing, with a focus on full-length sizing. Next Massaro explains how primers work and he demonstrates how to seat primers. There is a video dedicated to bullet choice, followed by a video on bullet seating, both with and without crimping. Today’s video showcase concludes with a helpful video on troubleshooting, showing how to check your ammo and disassemble rounds when something isn’t right.

Basics Of Reloading
What goes into reloading ammo? Here are the five basic handloading steps — removing the primer, resizing the case, inserting a new primer, adding powder, and seating a new bullet. Gun Digest also has a related video on Reloading Tools, explaining the basic tools you’ll need: dies, press, scale, powder measure or powder-dispensing machine, and measuring tools.

Case Prep and Resizing
The reloading process starts with your cartridge brass. You need to remove carbon from the case exterior, check for case damage and signs of incipient separation. And it often makes sense to clean the primer pockets. It’s also wise to check case length, and chamfer/debur the case necks (as needed). Then the cases should be resized before loading. We recommend full-length resizing for rifle rounds.

Primer Types Explained
What is the difference between a large rifle primer and a magnum large rifle primer? Can you use magnum primers in standard cartridges and vice versa? These are among the topics discussed in this video.

Priming Procedures — Using Press or Hand Tool — and Powder Throwing
In this video, Philip Massaro tackles primer installation, the first process of assembly in reloading and case charging. Learn the differences between large and small primers, and how to use a primer cup accessory on a single stage press. Then Massaro shows various methods to dispense the correct powder charge.

Bullets — How to Select the Right Projectile for your Application
Not every bullet is appropriate for every job. Find out what projectile you’ll need to win a shooting match or put meat on the table. Not all bullets are created equal — hunting bullets are different than match bullets and varmint bullets are different than big game projectiles. With this in mind, Phil Massaro examines different bullet designs — including a look at Nosler’s line of projectiles.

Cartridge Completion — Bullet Seating
In this installment, Philip Massaro covers the final step in cartridge assembly, bullet seating. He covers how to use a micrometer seating die for reloading, as well as various ways to crimp handgun bullets. Massaro demonstrates seating bullets for the .357 Mag, .45 ACP, .30-06 Springfield, and .458 Win Magnum cartridges. The video also covers using a roll-crimp and taper crimp.

Reloading Troubleshooting
This is a very important video, that shows how to troubleshoot potential problems with handload ammunition. The host shows how to check for potential case head separation and other brass problems. He shows how to get stuck cases out of dies using the drill and tap procedure. Also covered are collet bullet pullers and inertia hammers for removing seated bullets from cases. This is necessary if you mistakenly seat too deeply or forget to charge the case with powder.

Guide to IMR Enduron Powders — Temp Stable, Reduced Fouling

IMR Enduron Powder 4166 4451 7977

Have you tried IMR Enduron powders yet (IMR 4166, 4451, 4955, 7977, and/or 8133)? We’ve been impressed with what we’ve seen. IMR’s line of Enduron extruded powders offer excellent temp stability, reduced copper fouling, and good load density for many popular cartridges (such as .223 Rem, 6mmBR, .308 Win, .30-06, 300 WSM to name a few). Some of our Forum members have reported excellent results with IMR 4166 in the 6mmBR, Dasher, 6.5×47 Lapua and .308 Win. One member wrote: “in my 6.5×47… 4166 gives speeds and accuracy pretty much exactly the same as Varget.” And other shooters have observed reduced copper fouling with Enduron series powders, so IMR’s Enduron anti-fouling chemistry does seem to work.

IMR now offers five (5) Enduron powders: IMR 4166, IMR 4451, IMR 4955, IMR 7977, and IMR 8133. Shooters looking for good alternatives to hard-to-find extruded powders should definitely check out the Enduron line-up. Precision shooters will find an Enduron option well-suited to most popular precision cartridge types. For example, IMR 4166 is a good replacement for Hodgdon Varget (commonly used in the .223 Rem, 6mmBR and .308 Win), while IMR 4955 is a fine substitute for H4831 (favored by F-Open shooters for the .284 Win and 7mm WSM cartridges).

The Enduron Line-Up of Five Powders

IMR now offers five Enduron powders that cover a broad range of burn rates. They are suitable for a wide variety of cartridges, from small varmint cartridges all the way up to the .338 Lapua Magnum.

IMR Enduron Powders

IMR 4166 possesses the fastest burn rate in the Enduron lineup. It is the perfect burn speed for cartridges such as .308 Win, 7.62mm NATO, 22-250 Rem and 257 Roberts. A versatile, match-grade propellant, IMR 4166 is comparable to Hodgdon® Varget.

IMR 4451 is a mid-range burn speed powder, ideally suited for cartridges such as .270 Winchester, .30-06 and 300 Winchester Short Magnum. This powder is comparable to Hodgdon H4350.

IMR 4955 is a medium burn speed powder, falling in between IMR 4451 and IMR 7977 in burn speed. It provides top performance in big game cartridges such as 25-06, 280 Remington and 300 Winchester Magnum. This powder is comparable to Hodgdon H4831.

IMR 7977 is a slower burn rate in the Enduron family. Loading density is perfect for magnums. This is a true magnum propellant yielding outstanding performance in .300 Winchester Magnum, 7mm Remington Magnum and .338 Lapua Magnum. IMR 7977 is comparable to Hodgdon H1000.

IMR 8133 IMR Enduron 8133 is the slowest burn rate in the Enduron family. Loading density is perfect for the very large magnums, including the 6.5mm and 7mm magnums. This is a true magnum propellant yielding outstanding performance in 6.5-300 Weatherby, .264 Win Mag, 28 Nosler and .300 Rem Ultra Mag, among other cartridges.

IMR Enduron Technology powders are sold in one-pound (1 lb) and eight-pound (8-lb) containers through quality retailers including Graf & Sons, Midsouth, and Powder Valley. Check frequently for current availability as these will sell out quickly after arrival. Also check your local sporting goods dealers for recent powder shipments.
