Podcast – Max Michel and Bob Vogel, Competitive Shooters

Posted June 22nd, 2010 in General, podcast, shooting sports by Rob

Max Michel and Bob Vogel come on the podcast and discuss their practical shooting success this year.  Bob and Max are both fresh off of their wins(Bob-Limited, Max-Open) at the Area 5 Championship.  Listen to their stories, strategies, and insights.

We recorded the show live on Monday and had a caller ask a great question about how to get his son involved in practical shooting.

Check out video of Bob at the Area 5 Championship.

Podcast — Shooting at Bulletproof Glass and Cars

Posted June 15th, 2010 in General, podcast by Rob

Old_Painless of comes on the show to discuss his experience ballistic glass or bullet-resistant glass with a number of different rifle and handgun calibers.  We also discuss bullet deflection when shooting through angled glass like a windshield.

Interview Notes:

Rob starts out by discussing the youtube video of the Non-Standard Tactical Truck in which 7.63×39 rounds are fired at the truck with people inside.(1:09)

Polycarbonate Bulletproof Glass:

Old_Painless had some Polycast mailed to him.  It was a cast acrylic sheet about 1 1/4″ thick.  It was pretty heavy stuff and he shot at it with a variety of different ammunition.  It stopped .22lr, 9mm, 45ACP, etc.(Pistol rounds)

“Rifles are rifles and pistols are pistols.”

When he moved to the rifle ammunition, it started damaging the glass much more than the pistol ammunition.

Rob offers up an example of the difference in power between rifles and pistols.

The 12 gauge slug and .45-70 were able to break through the polycarbonate bulletproof glass.  He mentioned that some have suggested that the test results were skewed because of the rounds fired at the glass prior to the 12 gauge slug and the .45-70, but he found it hard to deny how easily those 2 projectiles went right through the glass.

Laminated Bulletproof Glass

More recently, someone sent him some laminated bulletproof glass.  The laminated bulletproof glass is a different type of material all together.  This glass was also about 1 1/4″ thick, but it was composed of 3 different sheets that were laminated together with a soft, rubbery adhesive.  When fired upon, the first piece will shatter, the the adhesive will help absorb the impact.

If you continue shooting the same spot multiple times, you will end up “chewing” through it.  When the outer layers shatter, the adhesive keeps most of the pieces attached as an extra barrier.

He was also given some laminated bulletproof glass rated for rifles.  This glass was about 2″ thick and was much heavier.  The 20″x20″ sheet weighed about 70 lbs.  This material is commonly used in armored vehicles.  He shot it with various rifle rounds including 12 gauge slugs and armor piercing rounds  and it stopped all of them for the first few rounds.  Like the lesser rated laminated bulletproof glass, multiple rounds fired in the same spot could still “chew” through the glass.

In conclusion, this stuff works.  Most armored vehicles would not allow multiple shots on the same spot.  Hopefully the vehicle would be on the way out of the area as soon as they realized they were coming under fire.

We also move into discussing the ballistics of shooting at a normal vehicle window.  He mentions the Buick-of-truth writeup by JohnWayne777.  When shooting through a front windshield, the angle causes pistol bullets to be deflected several inches.

If you are shooting out of a car’s front windshield, your projectile will hit higher than the point of aim.
If you are shooting into a car’s front windshield, your projectile will hit lower than the point of aim.

In the tests, the bullets were hitting 4-6 inches high/low with a .40 S&W or 9mm Luger.

Rob and Old_Painless recommend that everyone go and test with their own Buick-of-truth.

Old_Painless points out that secondary and following shots will not have to deal with the same amount of deflection.

Ruger LCR .357 and SR-556 Carbine Details

Posted June 8th, 2010 in General, podcast, Uncategorized by Rob

Mark Gurney from Ruger comes on the show to discuss the new guns that were announced at the NRA Annual Meeting.

Ruger LCR .357 Magnum Revolver

The standard .38 Special +P LCR gets a boot grip and XS Standard Dot Tritium Sight. The boot grip is a smaller, smoother grip that is easier to get in and out of the pocket. It is still a Hogue grip and helps absorb shock. These 2 features are paired as one new project.

The new .357 Magnum brings the weight of the gun up to 17.1oz because of the new steel frame that replaces the previous aluminum frame. Mark has found that the 158 grain bullets can be a bit much, but the 125 grain bullets are “perfectly manageable.” He has even found the 110 grain .357 Magnum loads in the new .357 LCR to be easier to shoot than the .38 Special +P loads in the original LCR.

Mark recommends that recoil sensitive shooters try .38 Special +P loads in the new .357 Mag LCR.  The extra weight of the gun makes them much easier to shoot.

Mark also mentions the patented LCR non-stacking trigger.  He mentions that this trigger starts out at about 6#s and builds to about 10#s before letting off.  This makes it easier to get the trigger “started” and feels much smoother and lighter.

Rob goes back to remind people that the small weight increase is still a good percentage of the entire weight of the gun and makes a big difference in recoil reduction.

Rob asks about the .357 LCR cylinder size in comparison to the .38 Special +P model.  Mark confirms that they are the exact same size, but the fluting is different.  Both cylinders are 1.283″ in diameter.

Mark also mentions the the other minute differences in the frame and how they improve the gun.  Ruger added bevels to the frame at rear of the barrel where the cylinder aligns with the frame. (see pointer below)

This minute bevel reduces spitting and moves flash from the cylinder gap forward and away from the shooter.

The .357 LCR uses “Carpenter 465″ stainless steel in the barrel and cylinder.  This is the same material used in the .454 Cassull revolvers.

Rob confirms that none of the cosmetic and internal changes keep the .357 model from using the same holsters as the .38 Special +P LCR.

Ruger SR-556 Carbine

The original SR-556 uses a heavy contour barrel(.850″ under the hand guard and .750″ in front of the gas block).  This makes for a muzzle heavy gun(typical of piston guns).  The new gun is in response to customer feedback asking for a lighter gun for faster transitions.

Some weight is removed by shortening the barrel and still keeping it legal with an integrally machined flash suppressor(as opposed to pinned and welded).  With the integral suppressor, the barrel is 16.125″(16 1/8″).  The rifled barrel is about 14.5″.  This removed about 1.75″ inches from the barrel of the gun.  Please note: This is NOT a short barrel rifle!

The barrel is also fluted beneath the hand guard.  Between the shortening and fluting, .5 lbs was removed from the front of the gun.  Mark says it is easily felt in handling and moving target to target.  Mark cautions that it does have more muzzle rise, but that is the trade-off.

Because the carbine version has the flash suppressor integrally machined, it cannot be removed or replaced with compensators, suppressors(sound), etc.  You would want to use use the original SR-556 if your intend to replace the flash suppressor.  BTW, Mark recommends a Torx T60 bit to remove the flash suppressor on the original SR-556.  It matches the flutes in the flash suppressor.

Mark says that the integrally machined flash suppressor does not contribute to additional accuracy although shorter barrels tend to shoot more accurately because they exhibit less barrel whip.  In testing, they found that the carbine was slightly more accurate that the original SR-556.  “We’re talking a couple tenths of a minute of angle here.”

Also remember that the shorter barrel length will lose some muzzle velocity.
