Hoppe's gun cleaning how to videos youtube #9

Hoppe’s has added new videos to its “How to Clean” Series, which provides step-by-step cleaning instructions for some of today’s most popular firearms. The 15-part video series can be seen on YouTube, Hoppes.com, and Hoppe’s Facebook page. There are now 15 Hoppe’s How-to-Clean videos hosted on Youtube and the Hoppes website.

Firearms Featured in Hoppes Gun Cleaning Series:
Glock 17
Mossberg 500
Remington 700
Remington 870
Remington 1187
Ruger 10-22
Ruger LCP II
Ruger PC Carbine
Ruger Vaquero
Savage 555
Savage MSR-15
Smith & Wesson Model 36
Smith & Wesson M&P Shield
Springfield 1911 A1
Winchester Model 70

Developed to provide effective, yet easy-to-follow cleaning instructions for a variety of different firearms, the Hoppe’s video series is a very helpful resource for first time gun owners. The “How to Clean” series also serves as a valuable refresher course for any firearms enthusiast. In the videos, host Luke Williams (Outdoors By Luke), covers recommended cleaning procedures for numerous popular rifles, pistols and shotguns. Below we link four videos from the series: Remington 700, MSR-15, Mossberg 500, and Smith & Wesson M&P Shield.

How to Clean Remington 700 Rifle

IMPORTANT NOTE: Here at AccurateShooter.com, with our custom match rifles, we may use different methods than shown above. Our preferred cleaning procedures may employ both different tools and different cleaning solvents/supplies. For example we like to use Wipe-Out foaming bore cleaner with two applications while the barrel is still warm. With every new barrel, we recommend cleaning conservatively until you learn what works best for your particular barrel and shooting style. Long strings of rapid-fire shooting can create tough barrel-fouling issues that may not arise when shooting slow-fire and cleaning every 40-50 rounds. In addition, some powder types foul much worse than others.

These Videos Are Particularly Useful for New Gun Owners
“As the industry welcomes more first time firearms owners than ever before, the need to provide helpful cleaning instructions has never been greater”, said Eliza Graves, Sr. Brand Manager for Hoppe’s. “Through our instructional video series, longtime and novice gun owners alike can easily find helpful tips that will keep their firearms running like new”.

Firearm Science: Eye Dominance, Eye Protection, Irons vs. Optics

firearm science NRA Jessie Duff Harrison

NRA Media offers a series of 40 informative videos about the Science of Shooting, covering a wide range of topics, from eye dominance to long-range ballistics. These videos feature high production values, with super-slow motion segments, as well as helpful computer graphics to illustrate the principles covered.

The videos are narrated by Jessie Duff, a top action pistol shooter (and the first women ever to achieve USPSA Grand Master status). Jessie is assisted by talented shooters such as Top Shot Season 4 Champion Chris Cheng. There are forty videos in the Firearm Science Video Series. Here are five NRA videos, with links to others below. You’ll find all 40 NRA Firearm Science Videos HERE.

Eye Dominance — How to Determine Which Eye is Dominant

Host Jessie Duff and longtime shooter Krystie Messenger demonstrate how eye dominance affects aim and teach you how to determine your dominant eye in this edition of Firearm Science. There are very simple tests you can do to determine your eye dominance. This Editor is right-handed but left-eye dominant. All competitive shooters should check for eye dominance. If you are cross-dominant, you can alter your head position or put a paper patch on one frame of your shooting glasses.

Eye Protection — Effect of Different Color Lenses

No matter what you’re shooting, eye protection should always be worn. But with so many choices, what should you wear? In this edition of Firearm Science, two-time Olympic trap shooter Corey Cogdell explains lens color options for protective eyewear. Different colors may be selected according to the light conditions and the sport. For most rifle shooters using magnified scopes, clear lenses are probably the best choice, except on very bright summer days.

Iron Sights vs. Optics

Host Jessie Duff and shooter Krystie Messenger demonstrate the benefits and drawbacks of using iron sights and optics in this edition of Firearm Science. For AR-type rifles, choosing the right option depends on the intended use of the rifle and the rules of competition. For example, a “Standard military Rifle” for CMP competition must have iron sights. But current NRA service rifle competition (and CMP unlimited military rifle class) allows scopes. Olympic smallbore shooters and Palma shooters have shown that extreme accuracy IS possible with sophisticated target sights. Below is the iron-sights Palma rifle with which John Whidden (Whidden Gunworks) won NRA Long-Range National Championships.

How Do Bullets Fly — Great Online Resource Explains Key Factors

Bullet External Ballistics
“The overturning moment MW tends to rotate the bullet about an axis, which goes through the CG (center of gravity) and which is perpendicular to the plane of drag….

Ruprecht Nennstiel, a forensic ballistics expert from Wiesbaden, Germany, has authored a great resource about bullet behavior in flight. Nennstiel’s comprehensive article, How Do Bullets Fly, explains all the forces which affect bullet flight including gravity, wind, gyroscopic effects, aerodynamic drag, and lift. Nennstiel even explains the rather arcane Magnus Force and Coriolis Effect which come into play at long ranges. Nennstiel’s remarkable resource contains many useful illustrations plus new experimental observations of bullets fired from small arms, both at short and at long ranges.

Bullet External Ballistics

A convenient index is provided so you can study each particular force in sequence. Writing with clear, precise prose, Nennstiel explains each key factor that affects external ballistics. For starters, we all know that bullets spin when launched from a rifled barrel. But Nennstiel explains in greater detail how this spinning creates gyroscopic stability:

“The overturning moment MW tends to rotate the bullet about an axis, which goes through the CG (center of gravity) and which is perpendicular to the plane of drag, the plane, formed by the velocity vector ‘v’ and the longitudinal axis of the bullet. In the absence of spin, the yaw angle ‘δ’ would grow and the bullet would tumble.

If the bullet has sufficient spin, saying if it rotates fast enough about its axis of form, the gyroscopic effect takes place: the bullet’s longitudinal axis moves into the direction of the overturning moment, perpendicular to the plane of drag. This axis shift however alters the plane of drag, which then rotates about the velocity vector. This movement is called precession or slow mode oscillation.”

Raise Your Ballistic IQ
Though comprehensible to the average reader with some grounding in basic physics, Nennstiel’s work is really the equivalent of a Ph.D thesis in external ballistics. You could easily spend hours reading (and re-reading) all the primary material as well as the detailed FAQ section. But we think it’s worth plowing into How Do Bullets Fly from start to finish. We suggest you bookmark the page for future reference. You can also download the complete article for future reference and offline reading.
