Gongzilla! Giant 72″x72″ Three-Element Steel Gong

A few seasons back, Forum member Rick from Louisiana (aka RMulhern) rigged up a fantastic target for long-range shooting. Rick, a long-time competitive Palma shooter, had a large 72″x72″ steel target fabricated with two separate center rings that are equivalent to the official paper Palma/Creedmoor target. He says he’s “shot a lot of Palma on that target, as well as lots of Black Powder Cartridge (BPCR) rounds”. The big steel target works great when Rick shoots his Sharps 45/110 BPCR at 800 to 1000 yards. The large steel background (painted white) helps Rick see and hear his hits. If you understand the high-arching trajectory of 500+ grain projectiles shot from a 45/110, you know it can take a few rounds to get Point of Impact dialed in.

Rick reports: “These are two of my favorite rifles to shoot: a M1874 Shiloh Sharps in caliber 45/110 (2 7/8) made in Big Timber, Montana by Kirk Bryan and family. The other is a 6.5×47 Lapua on a blue-printed M700 action with 1:8.5″-twist Krieger barrel and F5 McMillan Tactical stock. Many of the shooters that take up BPCR have a tendency to get away from their smokeless powder rifles in favor of the blackpowder game. Frankly I have the best of both worlds as I enjoy shooting both (smokeless and BPCR), although I must admit that I probably spend the majority of my time on the range with the Sharps rifles these days.” (Rick’s pretty good with his Sharps by the way — he recently shot a 95, 96, and 100 (clean) for 3×10 shots at 800 yards.)

Gongzilla: $1000 Worth of Steel with Three Plate Layers
Rick tells us: “Here’s the deal — everything is steel! The large plate is 72″x72″ and the black bull is 44″ diameter. The 20″-diameter central white bull is made from 1/2″-thick AR400 bull-dozer plating. That’s the same size as the regulation Palma/Creedmoor paper target. The white square and black bull are 3/8″-thick mild steel. Plates are off-set 2″ from each other. I welded a 2″ length of square tubing to the back of both plates and the bolt slides through and is attached to the large plate. I used 2 3/8″ upset tubing (oil field pipe) for the holder framing.” Rick says he invested about $1000.00 in metal for the target, but that was 15 years ago. Today the steel would be much more expensive.

Rick says the AR400 armor plate in the center bull is very strong: “You can shoot a .338 Lapua Magnum at 200 yards and it won’t damage the center bull”. The mild steel works well for the cast bullets Rick uses with his Sharps 45/110. Also, Rick says the mild steel is rugged enough for 6.5mm and .308 hollowpoint match bullets, if you’re at least 500 yards away. However, Rick told us, “If I would make [the target] again, I would make the black bull AR400 as well. [That way] you would never have to worry about big dents or beating the plate up at any distance. The AR400 is very tough steel. You can shoot a Sierra or Lapua HP bullet and they will just splatter.”

Rick told us: “I built this target with off-set clanger plates. The white clanger is AR400. Bullets just splatter!” Does he worry about hitting the bolt head? Not at all. Rick says: “When I hit the bolt head, I break my arm patting myself on the back!”.
