Barnes 180 TSX vs Hornaday 190 SPBT

I know that moose and brown bears are not made of steel but I thought the results of a simple test today were interesting.

I set up a 48" x 12" x 0.5" steel plate up at 300 meters today and tested the barnes 180 TSX and the Hornaday 190 BTSP. NOT the 190 match, rather the hunting version. Both were fired from my 300 RUM at near the same velocities.

1: 88.5 grains of RL-25 with the 190 BTSP. Average velocity of 3250. Both shots blew completely through the steel. In one of the holes most of the jacket was left in the hole and was recovered. Impact velocity is in the ball park of 2550 FPS.

2: 84.0 grains of RL-25 with the 180 TSX. Average velocity of 3216. Both shots stopped cold. Both bullets were pryed out with a screwdriver. There was about .3" raised dent on the back side of the steel. Impact velocities were around 2475.

The test done here was not to bash any one bullet over another or prove a superiority. In all reality it proves nothing usefull for a hunting scenario. It does illustrate however that my theories are not always right. My theory was that the jacketed lead bullets would make a divot and fragment into oblivion and the the solid copper bullet would pass through like a hot knife through butter. Obviously, the lead core held up better than I expected and passed right on through where the solid copper bullet expended 100% of its available energy. 2 very different results much to my suprise.

I also talked with the tech department at Barnes today. Their claim was that the 30 cal 180 TSX and TTSX would expand as low as 1800 FPS. They stated that the test medium they use is water and that his opinion was that tissue and bone would help expansion concluding that they would open on game at even lower velocities than 1800 FPS.

Happy shooting!!

The faster bullet will penetrate the most steel (A-36 plate). Even a 55 grain varmint bullet at 3600 FPS will nearly penetrate a 1/2" A-36 plate the first shot. Shoot AR-500 plate and it will barely be scratched. Most steel plate will be A-36 any hard type plate is special order

Yeah I get that, I just still thought that the solid copper would have gone through even though it was only a small amount slower. I shot some 175 SMK's a few days prior at 2900 and they made a deeper crater than the TSX.

Shoot an animal and I'll wager that the TSX will be the deepest penetrater


180 TSX made some pretty good creators in this 1" thick A-36 plate gong at 300 yards shot from my 300 win

I tend to agree. I shot an 1800# bull moose a number of years ago with the 180 XBT and the 2 bullets recovered there was a substantial amount of bearing surface and boat tail behind the mushroom. This "weight" behind the shroom is what one needs for deep penetration. A flat bullet is pretty useless. I dug a 200 ACCUBOND out of one of my rams a couple years ago that was pretty flat. Of course it was launched above the factory recomended specs.

Re: Barnes 180 TSX vs Hornaday 190 SPBT

I have found that penetrating steel & good penetration in flesh are 2 totally different things.

The 22 cal bullet is a case in point & sometimes a LBT style bullet in .429 or .451 may not do that well in steel, but yet can completely penetrate a Bison. As another mentioned, in flesh my money would be on the TSX, at least when it comes to penetration.

Meichele, i would have bet the farm the results would have been the other way. very interesting, thanks for sharing.
i remember in, i think it was PO Ackley's book he described shooting into this steel plate. can't recall the dimensions, but nothing he ever shot would penetrate it, encluding full metaljacket bullets. until he tried a 220 swift with 55 gr bullets. it was the only cartridge that ever went through it.
