\"The<\/a>

The HT line of ammo from Sig Sauer was developed for hunting applications, but could also serve in defensive roles as well. One of the newest members of the HT family is the 60-grain .223 load.<\/p><\/div>\n

We\u2019re going to test out three new hunting loads from Sig Sauer Elite Performance Ammunition<\/a>, and in the process, tell you how you can win a year\u2019s worth of Sig Sauer ammo. Read on.<\/p>\n

The HT family<\/a>, now numbering three (300 Blackout, .308 Winchester, and .223 Remington) is intended for various hunting applications. Which ones depend on the caliber. At the high end is the .308 and for varmint and predator use, the .223. In the middle is the supersonic 300 Blackout round. The all-copper HT bullet design common to all three is designed to expand aggressively while remaining in one piece, even as it travels through tough targets. That helps develop consistent and predictable penetration. Today we\u2019re going to take a look at the two newest loads chambered in .308 and .223 and one that\u2019s been on the market for about a year, the 300 Blackout HT.<\/p>\n

“We wanted to create an extremely accurate, effective, and environmentally friendly line of\u00a0hunting ammunition and designed the Sig Sauer HT rounds using all-copper bullets that deliver deep penetration and consistent 1.8x diameter expansion,” said Dan Powers, President of the Sig Sauer Ammunition Division. \u00a0“We also designed the nose geometry of the Sig Sauer HT ammunition for superior feeding in AR-style platforms and now offer this round in Supersonic 120-grain 300 Blackout, 150-grain .308 Winchester and 60-grain .223 Remington.”<\/p>\n

As the name implies, the HT line is designed for hunting, but as long as you understand what these rounds are designed to do, they\u2019ll make excellent defensive choices too. These projectiles are designed to penetrate with predictable expansion, so if your defensive application is not sensitive to penetration of walls and such, check it out.<\/p>\n

\"This<\/a>

This is what the HT bullet is all about. Shown here is an expanded 300 Blackout 120-grain projectile.<\/p><\/div>\n

Before we get started with testing, let\u2019s take a quick look at the factory specs for the three HT loads.<\/p>\n

Sig Sauer HT .223 Remington<\/strong>
\nBullet Weight: 60 grains<\/em>
\nVelocity: 3,100 feet per second<\/em>
\nEnergy: 1,280 ft-lbs<\/em><\/p>\n

Sig Sauer HT 300 Blackout<\/strong>
\nBullet Weight: 120 grains<\/em>
\nVelocity: 2,250 feet per second<\/em>
\nEnergy: 1,349 ft-lbs<\/em><\/p>\n

Sig Sauer HT .308 Winchester<\/strong>
\nBullet Weight: 150 grains<\/em>
\nVelocity: 2,900 feet per second<\/em>
\nEnergy: 2,801 ft-lbs<\/em><\/p>\n

All of the HT rounds use common features like low-flash propellant, nickel-coated cases for slick feeding and corrosion resistance, and upgraded primers for velocity consistency.<\/p>\n

\"Like<\/a>

Like the other members of the family, the .308 cartridges use upgraded primers and nickel-plated cases for corrosion resistance and smooth feeding.<\/p><\/div>\n

Accuracy<\/h2>\n

To test out the new Sig Sauer HT Hunting Ammunition, I chose a new hunting rifle chambered in .308, a full length 300 Blackout AR-15 rifle, and \u201cmy version\u201d of a hunting rifle chambered in .223 Remington.<\/p>\n

For the .308, I used the new Thompson Center Compass bolt-action. We took a close look at this rifle recently, and you can find the details here<\/a>. The folks at Thompson Center have made a career out of building accurate rifles that regular humans can afford. This one not only retails for $399, but it also comes with a one minute of angle guarantee provided you use match ammunition.<\/p>\n

On the .223 side, I\u2019m just an AR guy at heart, so I chose the FN-15 DMR (Designated Marksman Rifle) for the test platform. Besides, this ammo is billed as varmint and predator optimized, so it\u2019s got AR-15 written all over it. The DMR rifle has an 18-inch barrel and has proven to be plenty accurate with the right ammunition. I topped it with a Burris XTR II scope. With its 2-10x magnification, bright 34mm tube, and very fine reticle, it allows a precise sight picture at the standard 100-yard accuracy testing distance.<\/p>\n

For the 300 Blackout, I used a Daniel Defense DDM4v5 AR-15 rifle with a 16-inch barrel.<\/p>\n

\"I<\/a>

I had little trouble getting 100-yard, five-shot groups like this with the 300 Blackout HT load.<\/p><\/div>\n

I fired five-shot groups from 100 yards for the .223 and 300 Blackout. Given the design and purpose of the Thompson Center Compass rifle, I fired three-shot groups also from 100 yards.<\/p>\n\n\n\n\n\n\n
Rifle<\/td>\nAmmo<\/td>\nGroup Size<\/td>\n<\/tr>\n
Thompson Center Compass<\/td>\nSig Sauer HT .308<\/td>\n1.55\u201d<\/td>\n<\/tr>\n
Daniel Defense DDM4v5<\/td>\nSig Sauer HT 300 Blackout<\/td>\n1.40\u201d<\/td>\n<\/tr>\n
FN-15 DMR<\/td>\nSig Sauer HT .223<\/td>\n3.1\u201d<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

For some unknown reason, the .223 HT load and my FN-15 DMR didn\u2019t get along so well. I fired six very careful groups to be sure, and if nothing else, the group sizes were consistent. They ranged from 2.85 to 3.62 inches. The same rifle regularly prints sub-one-inch, five-shot groups with match ammunition, so I\u2019m not exactly sure why the performance didn\u2019t compare with that turned in by the .308 and 300 Blackout loads.<\/p>\n

\"The<\/a>

The HT projectiles are designed to start expansion almost immediately.<\/p><\/div>\n

Velocity<\/h2>\n

To keep things consistent, I used the same three rifles for velocity testing. I set up my now almost shot to pieces Shooting Chrony Beta Master Chronograph. Hey, when you shoot thousands of rounds through one of these, you\u2019re bound to have some strikes now and then. That\u2019s my story, and I\u2019m sticking to it. Anyway, I placed the unit 15 feet down range and proceeded to shoot 10-round strings to get average figures and measures of consistency. Here\u2019s what I found.<\/p>\n\n\n\n\n\n\n
\u00a0<\/strong><\/td>\nAverage Velocity<\/strong><\/td>\nExtreme Spread<\/strong><\/td>\nStandard Deviation<\/strong><\/td>\n<\/tr>\n
Sig Sauer HT .223<\/td>\n2,664.2<\/td>\n48<\/td>\n13.6<\/td>\n<\/tr>\n
Sig Sauer HT .308<\/td>\n2,898.8<\/td>\n95<\/td>\n31.6<\/td>\n<\/tr>\n
Sig Sauer HT 300 Blackout<\/td>\n2,421.8<\/td>\n31<\/td>\n9.1<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

 <\/p>\n

While the .308 showed a little more movement around the average, the other two loads were exceptionally consistent in terms of recorded accuracy and variance. Velocity spreads from highest to lowest of just 31 and 48 feet per second are impressive. That\u2019s clearly a result of finicky production methods assisted by use of match-type primers.<\/p>\n

Expansion<\/h2>\n

These all-copper HT projectiles are designed to expand in a dramatic way. Per the factory specs, the ideal expansion is 1.8x original diameter. Since they\u2019re all copper, they should maintain most of their original weight, even when passing through tough targets. I didn\u2019t have a long line of tough target volunteers, so I shot into Clear Ballistics gelatin blocks to get a view of what the expansion pattern looks like.<\/p>\n

\"These<\/a>

These two .223 HT bullets performed identically, penetrating Clear Ballistics gelatin to a depth of 24 inches.<\/p><\/div>\n

The 300 Blackout bullet, fired from the Daniel Defense rifle with its 16-inch barrel, expanded to a whopping .63 inches. That\u2019s just over double the starting diameter of the projectile. As for penetration, the projectile came within two inches of exiting the second block. That\u2019s 30 inches of penetration through Clear Ballistics gel. I weighed the recovered bullet and found that it gained a little, coming in at 120.1 grains. That was a result of a little bit of gel stuck under the petals.<\/p>\n

I fired a couple of the .223 HTs into 16-inch Clear Ballistics gelatin blocks. Since I wasn\u2019t sure how much penetration I\u2019d see, I put two blocks end to end. That turned out to be a good plan because both projectiles stopped at almost the exact same position in the second gelatin block. Total travel was 24 inches. After digging out the bullets, I measured the maximum diameter and found one expanded to .463 inches and the other to .455 inches. Considering that both of these should have measured .224 inches before firing, they also expanded to over double the original diameter. These two projectiles gained a bit of gelatin weight as well, weighing 60.1 and 60.5 grains. The takeaway is that the bullets remained intact and didn’t shed pieces along the way.<\/p>\n

\"Both<\/a>

Both of these .223 HT bullets expanded to over double their starting diameter.<\/p><\/div>\n

I ran out of gel blocks by the time I got to .308, but given the performance of the other two calibers, I\u2019d expect similar results.<\/p>\n

\"The<\/a>

The 120-grain 300 Blackout bullet penetrated to a depth of 30 inches and expanded to over double original diameter.<\/p><\/div>\n
