Rick, a long-time competitive Palma shooter, had a large 72&#8243;x72&#8243; steel target fabricated with two separate center rings that are equivalent to the official paper Palma/Creedmoor target. He says he&#8217;s &#8220;shot a lot of Palma on that target, as well as lots of Black Powder Cartridge (BPCR) rounds&#8221;. 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.</p>
<p>Rick reports: &#8220;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&#215;47 Lapua on a blue-printed M700 action with 1:8.5&#8243;-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.&#8221; (Rick&#8217;s pretty good with his Sharps by the way &#8212; he recently shot a 95, 96, and 100 (clean) for 3&#215;10 shots at 800 yards.)</p>
<p><b>Gongzilla: $1000 Worth of Steel with Three Plate Layers</b><br />
Rick tells us: &#8220;Here&#8217;s the deal &#8212; everything is steel! The large plate is 72&#8243;x72&#8243; and the black bull is 44&#8243; diameter. The 20&#8243;-diameter central white bull is made from 1/2&#8243;-thick AR400 bull-dozer plating. That&#8217;s the same size as the regulation Palma/Creedmoor paper target. The white square and black bull are 3/8&#8243;-thick mild steel. Plates are off-set 2&#8243; from each other. I welded a 2&#8243; 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&#8243; upset tubing (oil field pipe) for the holder framing.&#8221; 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.</p>
<p><img border="1" src="https://accurateshooter.net/Blog/ricktarget02.jpg" alt="1000 yard steel bullseye target"></p>
<p>Rick says the AR400 armor plate in the center bull is very strong: &#8220;You can shoot a .338 Lapua Magnum at 200 yards and it won&#8217;t damage the center bull&#8221;. 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&#8217;re at least 500 yards away. However, Rick told us, &#8220;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.&#8221;</p>
<blockquote><p>Rick told us: &#8220;I built this target with off-set clanger plates. The white clanger is AR400. Bullets just splatter!&#8221; Does he worry about hitting the bolt head? Not at all. Rick says: &#8220;When I hit the bolt head, I break my arm patting myself on the back!&#8221;.</p></blockquote>
