Boom Boom's Prototype Pistol Trap Is Finally Built
Hi,
Well The Pistol Trap Is Finally Built With The Great & Patient Help Of Rassmusson Inc.
My Original Designs Were Much Improved By His Input. He Changed The Angles Slightly, Changed It To A Flattened 4 Sided Cone /funnel Shape.
This Redused Costs & Wt.
It Is On 2 Wheels & Can Be Moved Like A Wheelbarrow ,very Stable. I Use A 6' Ramp To Get It In & Out Of My Toyota Truck. As It Is Too Heavy To Just Lift As I Am Now Pushing 60.
In Fact It Is So Heavy I Will Probibally Not Build The Planned Rifle Trap.
It Is Buil Out Of 3/8" Plate W/ Some 1/2" Welded At Rear.
There Is A Vertical Decelerator Pipe At Rear W/ A Removeable Top For Any Repairs If Needed.
The Decelerator Pipe Empties Into A Welded Bucket Made Of 1/2" Pipe & Plate.
I Used Used 2 Rubber Mats , The Type Commonly Use To Staple/tape Targets To On Commercial & Police Ranges.
1st Test Was W/38+p Lead 180gr. 50 Rounds, Then 38+p Jacked 6 Rounds, No Prob. At All, In Fact 2 Lead Bullets Did Not Compleatly Exit The Rubber Baffels In Front.
2nd Test Was V. Hot 180gr. Lead 357 50 Rounds. No Prob.
Then 6 Rounds V. Hot Jacked. 2 Small Scraches On Pipe.
Will Do Another Test On Thurs. Using 5 Rubber Mats On Front.
2nd Test Was W/
3rd Test Boom Boom's Bullet Trap
HI,
TEST 3,
50 YDS. 11 layers of rubber baffels/flaps
-44 MAG. 250GR. Pb bullet on top of 20grs. Wc820 . good results. 4-5 of the 50 rounds did not exit the last flap all the way.
100YDS- 7MM/06, 168 GR. Pb bullet on top of 24.5grs IMR4198 w/ DACRON FILLER.
GOOD RESULTS. A few of the 50 7MM bullets did not exit the last flap.
No damage to the trap, fair amount of Pb dust
4th Test Boom Boom,s Trap
HI,
FORGOT TO MENTION IN DESCRIPTION THAT THE PLATES ARE ON A 22&1/2 DEGREE ANGLE.
RESULTS SO FAR:
150 ROUNDS 180GR. Pb HARD CAST, WARM LOADS 38 SPECIAL NO DAMAGE TO TRAP USE 2-3 RUBBER FLAPS TO REDUCE Pb POWDER. 6 ROUNDS JACKED +P NO DAMAGE.
240 ROUNDS 180GR. Pb HARD CAST, VERY HOT LOADS! 357 NO DAMAGE TO TRAP.
USED 5-6 R. FLAPS TO REDUCE Pb POWDER. 6 ROUNDS JACKED 2 SMALL SCRACHES ON DECELERATOR PIPE.
50 ROUNDS 250GR. Pb HARD CAST, HOT LOADS, 44 MAG NO DAMAGE TO TRAP.
USE 11-12 R. FLAPS TO REDUCE Pb POWDER.
200 ROUNDS 168GR. PB AIR COOLED TW. SQUIB LOADS (1,300'/S), 7MM/06 NO DAMAGE. USED 5-6 R. FLAPS.
20 ROUNDS 168GR. HARD CAST MID RANGE LOADS (1,800-2,000'/S), 7MM06 NO DAMAGE. USED USED 11-12 r. FLAPS TO REDUCE Pb POWDER.
ALL FIRED AT 50YDS. NOW.
ANOTHER ADVANTAGE TO THE R. FLAPS IS THERE IS NOTHING COMING BACK OUT THE FRONT OF THE TRAP. RICORCHIE MIGHT BE A PROBLEM W/ STEEL PLATES AT LESS THAN A 45 DEGREE ANGLE.:Fire:
Boom Boom's Bullet Trap Update
HI,
Well I have made some modifications.
I cut off the metal tabs that I was bolting the rubber flaps to at the bottom, also I cut off the lower part of the vertical decellerator pipe to make easier to wheel.
Have fired over 1000 rounds of hot 357, 44's-50 rounds, 150- 38"s, and at least 750 - 7MM/06 into it most all at 50 yds. All save a few 38 & 357 rounds were cast.
When I moved to the mid-range velocity (about 1800-2000'/s) 7MM/06 loads the removable cap to the pipe rose up under impact so I am loosing about 1/2 the Pb out the top.
Only solution is to put something real heavy on it to hold it down or just weld it down , as far as I can see.
Also the rubber flaps are starting to look like shreaded wheat. I did assume at the start that I would have to replace them from time to time.
