Got finished with a home project and had some scraps of 3/4 plywood left over. Got to thinking about our recommendations for HD and my personal "first up" loads of #2 birdshot (12 ga).
I read somewhere (wasn't Hatcher's notebook - I checked) that the Army considers any projectile that can penetrate a given thickness of plywood (can't recall if 1/2 or 3/4) is also capable of a fatal wound. As I had the gun/range/ammo and 3/4 plywood onhand, the rest is revealed here...
Gun - 870 with a 20 inch cylinder choke. My thought was that the cyl bore would give the worst results - probably get better results as the choke increases.
Range - the longest shot reasonably available in my house is 34 feet down a hallway. Adding the patented Dave McC one yard put my peformance range at 12 yards.
Ammo - just to keep the brands together, I ran one round of Remington # 8s (3 1/4 dram, 1 oz.) promoloads, one round of Remington # 4 shot (probably 3 1/4 drams, 1 1/4 oz), one round of Winchester Turkey load # 6 shot (max drams, 1 5/8 oz) and one round of my hoarded Winchester # 2 shot, load data unknown.
I propped up my 4 ft x 10 inch piece of 3/4 plywood on a target stand as I wanted to make this a tough test. I figured if I secured it, the lack of give would increase the effectiveness. The first shot was with the load of number 2s - figured if they didn't penetrate, the rest of the test was unneeded.
First shot revealed a 8 inch pattern and complete passthrough of the number two shot. Given the collander appearance of the plywood, I'll stick to this as a suitable round for my use in my house.
Next up was the # 8 dove load. No passthroughs, same 8 inch pattern and some of the pellets were stuck in the surface of the plywood. I am aware that some prisons use this load or # 9s inside a cellblock. Frankly, unless your engagement range is five yards or less (rathole peformance), I'd pay another couple of bucks and get a better load.
The Remington number 4 Duck and Pheasant load did almost as well as the #2s. Seemed to have less but adequate penetration.
Last load tested was the Turkey load. The 1 5/8s ounces of #6 shot simply smashed what was left of the board and broke it in two pieces. I actually could not tell if true penetration took place as the splinters made it difficult. The impact of this load was impressive and bears additional testing.
There were a couple of other things I wanted to test - one was finding the line/distance where the number 8 shot started to exibit the rathole performance. My mistake was not realizing that my scrap plywood was going to be reduced to splinters quite so fast. In the near future, I plan to cut some 10 x 10 pieces of 3/4 plywood and run this portion of the test.
Thoughts/comments/suggestions?
