This bullet is widely acclaimed as possibly the most nearly perfect game bullet in the world. This bullet has the weight, ballistic characteristics, and most certainly the accuracy to be just that.

With match grade accuracy, the #1840 SBT bullet has taken many prize trophies throughout the North American continent and on the African plains.

I have shot two cow elk with the 150gr SGK out of my 270WSM. Last year's was a bang-flop chest shot at barely over 100yds. Went in between ribs on left side and broke two on right side going out. Hydraulic shock did a number on the boiler room; wound channel took out the lungs. She never tried to get up, just kicked a couple of times and expired. This year's was lasered at 465yds, farther than I guessed, so I hit lower than I would want. Bullet shattered right front leg at joint, penetrated/broke breastbone and shot through left front leg bone. Shock severely bruised heart and bloodshot both lungs. Jacket recovered just under off-side skin, right past shattered leg bone. Jacket-core separation is over-rated "problem." Two shattered legs and brisket coupled with fatal internal injuries is success story in my book! I have shot well over 100 Texas whitetail with Sierra bullets in my lifetime using several different calibers. They have always come through, and usually yield the best accuracy. The load I use for elk in my 270WSM has given 3-shot groups as small as 0.4" at 100yds.

When working up a long range load for my Savage 11 270 WSM I was a little frustrated with either my groups or speeds with those long poly tip bullets. Since SGKs gave such good accuracy in my other rifles I decided to give them a try and first time out they shot a one hole group at 100yds averaging 3010fps with a healthy dose of RL22, I tried that same load several more times yielding cloverleaf or better groups every time, while they don't have the .500+BC that some of the "high tech" bullets have there is no doubt that I will be using the Sierra come opening day. I load Sierra bullets in EVERY rifle cartridge I handload for, and after years of experience here is my honest opinion. 1 Across the board this is the most accurate bullet out there, a few rifles will shoot slightly tighter with another bullet but EVERYTHING shoots very well with the SGK even my super picky Browning. 2 After many heads of game I have never been disappointed with the terminal performance, the only gripe I have is sometimes they are a little TOO dramatic for smallish deer at full speed/close range forcing me to reduce speeds a bit or reach for my 7mm-08 or 6.5x55 instead of my 30-06 or various magnums to reduce meat damage. The furthest I have ever had a SGK hit deer run was 20 yards, and that was an accidental gut shot. 3 I have never had an instance of core/jacket separation, I think that "problem" is way too overblown by the bonded bullet market, especially when talking about deer/hog class game.

Excellent groupings in both my 270 Win and 270 WSM for target ( less than .625" at 100 yards in both) and superior penetration, expansion and knock down on 240 lb deer.
