Quick questions (and answers) for the impatient :

  • Which 9mm ammunition was best at penetrating a 1 inch OSB Plywood? All 6 types penetrated fully
  • Did any 9mm Luger ammunition fail to penetrate the 1 inch OSB Plywood? Um. No. Didn’t we answer this in the first question?
  • Based on this test, which 9mm ammo is best? Keep your pants on, junior! We don’t have nearly enough data to pick the “best”

*many of the links will take you to a trusted retail site where you will find additional product info and can purchase 9mm Luger ammunition, if you like.

The Ammo

Ammunition Supply Company provided the following ammunition for this test:

Winchester White Box 115gr FJM
Cci/Speer LE Gold Dot 115gr
G2 Research, INC RIP 9mm
Federal Premium HST 147gr
Dynamic Research Technologies- DRT Ammunition 85gr HP frangible
Remington Arms Company 115gr FMJ

The Test

One round of each 9mm ammo was fired at an undamaged section of 1 inch OSB Plywood from a distance of 7 yards.

Test gun: Century Arms Canik TP9SA pistol.

The Results

The rumors of the 9mm round having no punch have been exaggerated, folks. Not a single one of these rounds was stopped by the 1 inch OSB Plywood. Heck, none even left holes suggesting that they were slowed down much. The lesson here: If you ever have to look for cover, even from just a 9mm handgun, a wall made of 1 inch OSB Plywood won’t cut it. That may sound a bit obvious, but I know of several people that have outbuildings/sheds with walls made of 2 layers of 1/2″ OSB Plywood (one exterior layer, on interior layer on the other side of the framing studs). That is effectively the same thickness. I wouldn’t fault anyone that might have expected that type of wall to give them some protection. Although we now know that it doesn’t.

We started with one of our “control” rounds, the Winchester White Box 115gr FJM, which made what looked more like a dent than a hole on entry. It did slightly better on exit with a splintery divot smaller than a penny in diameter.

The Dynamic Research Technologies- DRT Ammunition 85gr HP frangible, made a fairly clean entry hole, then ripped up a penny sized section on exit.

The single shot of Federal Premium HST 147gr left the cleanest entry hole and a splintered mess on exit.

The Remington Arms Company 115gr FMJ made the messiest entry, looking like it merely pushed into the board instead of blasting through it. The exit hole, however, was one of the tighter, more clean exits… as one might expect from a rounded FMJ round.

The G2 Research, INC R.I.P. 9mm 100% copper, machined bullets sawed a rather clean hole on entry. Living up to it’s name, the R.I.P. ripped out more material on exit than any of the prior rounds in this test. Many of the prior rounds left a lot of splinters. The G2 left only the memory of the wood that had been there.

The Speer LE Gold Dot 115gr made a rather non-descript entry hole that really isn’t that impressive. The exit hole, though, was easily the biggest, having shed the most wood fragments.

Recovered bullets

Sadly, no bullets were recovered during the 1″ OSB plywood penetration test.

Conclusion

All rounds penetrated the 1″ OSB plywood, but the story told by the holes they left varied greatly:
In order of size of hole made, with the largest hole listed first:

  • The Speer LE Gold Dot 115gr made the biggest hole… again.
  • The diminutive 92gr, but scary looking G2 Research, INC R.I.P. 9mm made a cleaner entry hole and slightly smaller, but cleanest exit hole.
  • The Federal Premium HST 147gr left the cleanest entry hole
  • The two FMJ rounds mainly pushed material out of the way instead of tearing it, as the hollow point rounds did.

If your goal is simply to penetrate a barrier with maximum retained energy, then it appears the FMJ rounds transferred the least energy to the plywood.

Noting that none of the rounds so much at made a scratch on the second wall of the cinder block, given a choice I will reach for a centerfire rifle.

Beyond this, we found that the single layer of 1″ OSB plywood was insufficient to make further comments. We are working on future test protocols that call for multiple layers of barrier material, with the hope that we will be see evidence of expansion, and have bullets that do not pass through all layers of barrier.

Huge thanks to Ammunition Supply Company, who supplied the ammo for this test.
