Project SBS: Complete and Function Tested
Tuesday Nov. 23, 2010
Mossberg 590A1 'Compact' Short Barrel Shotgun (SBS) w OEM /14" barrel
Fixed modified choke
Hahn Precision receiver mounted 1913/Picatinny rail and oversized safety
Primary Arms 'Microdot' red dot sight [By way of the company owner who is not a hunter but thought my concept idea was interesting enough that he heavily discounted my purchase on the spot.]
OEM tritium front rifle type blade sight (Emergency)
Remington 'Slugger' rifled slug 2 3/4" 12GA
Brenneke 'K.O.' foster slug 2 3/4' 12GA
I'd though of this concept four years ago.
Began working toward it three years ago.
Today it comes to a close.
One shotgun (receiver and barrel) to meet four distinctly different tasks in functional capability.
1) Home Defense and Combat Shotgun [Efficient for storage within and navigating small spaces while being able to deliver good stopping power.]
2) Turkey hunting [Able to provide a controlled killing power cloud out to 40 yds.]
3) Deer slug gun [Able to direct precise projectile solids between 50 and 75 yds.]
4) Total cost of build at or less than $800 including all fees & taxes.
All three of these on the surface to traditionalists are opposite opposed.
But not if if you start from a book that has no pre-conceived notions and by that does not hold to convention for simple sake of being conventional (!).
I've had multiple folk tell me my plan was stupid and/or not possible both in person, including fellow instructors, as well as via the internets at various gunfu forums that shall remain nameless.
Well today the proof is in the pudding and all doubts have been put to rest.
The above target was shot by me as _off hand_ and _standing_ with _no sling_ and using no magnifying optics of any sort with _commercial_ ammo I'd bought from my local Dick's!
There were three other guys on the line with me today all firing high dollar deer slug guns every one using optics by normal convention, and they were firing as seated at a bench from shooting sleds with their guns strapped within to arrest recoil. Their results were same as mine.
I don't own a rest, have never shot from one...And don't have one with me when I'm in a tree stand (!) real world.
They stopped shooting to watch me shoot and take note of my results,to then ask; "What kind of gun is that?...That barrel is awfully short!"
One of the former RSOs from S&W drove up as I was leaving and we chatted about my results. He was stunned.
I told him it's just a matter of physics...And that shotguns and their shells contrary to popular belief are _not_ same as rifles and handguns as related to barrel length.
Anyway this project is now officially done and put to bed.
I'll be running this gun day after Thanksgiving toward winter deer in lieu of the Browning 16 gauge.
Oct. 24th, 2010
Same range...Same distance (50yds)...Same conditions standing off hand w/no sling...Though wind that day was not still but rather ~ 15mph right to left.
Then I have to request approval from the BATFE to take it out of state to NY so that I can use it as well toward the 2011 spring and fall turkey seasons.
To my mind this is the ultimate as they say 'Zombie' tool platform.
Slugs for intermediate trouble interdiction and shot of varying type for close up personal defense...In a package that easily will fit in a backpack.
If there was such thing as a zombie aside from mother rapers and child takers by the name of Deebo or Hayes.
Those shots at the bottom of the paper were my ranging shots as I was working to bring the elevation of the sight up across three tries to meet center of the 'Shoot N See' target.
I had to dial in 24 clicks of elevation to put these heavy 1 ounce projectiles at dead center as POA.
The group of five at the center were all in one continuous string being the IMHO VERY accurate & consistent Remington 'Slugster' shells. They are what I run in the 16 ga. and I get exact same hit what you look at exactly where you look at results.
The outliers to the outer edges of the paper were the Brenneke which had reduced recoil and with that longer barrel timing as well as time of flight. They are a lighter projectile as well which makes them inherently less accurate than the heavy and higher velocity (higher recoil!) Remington.
