The Thor™ Bullets produced by OPG Gun Ventures are patented, high performance, full-bore muzzleloading bullets. The .50 caliber ballistic tip, Thor™ Bullets are Colorado and California legal, which feature some of the harshest regulations for muzzleloader projectiles. The Thor™ Bullets are built on a limited-production basis, and are manufactured by Barnes™ using their X Bullet® Technology, with 100% copper construction and their expansion technology. The Thor™ Bullet is proven to be extremely accurate at long ranges, while providing lethal expansion on deer and elk-sized game. 

The Thor™ Bullets are a premium Barnes bullet with proven technology. The bullet’s hollow base expands when the powder goes off, both gripping the rifling and sealing the bore.  These bullets actually shoot 75-100 FPS faster than a Powerbelt, due to their superb sealing power. If it is a quality conical you are looking for, that won’t fragment into a million pieces, the conical, 250 grain Thor™ Bullet is the way to go.

**** Before purchasing your first pack of Thor™ Bullets, you will first need to order a test sizing pack of 4 bullets of diameters of .500”, .501”. .502” and .503” that allows you to correctly size your bore. It is important that you start with the smallest diameter Thor™ Bullet, and work your way up in diameter size until you find the proper fitting Thor™ Bullet for your muzzleloader. While manufacturers have similar bore diameters, they will vary .001”-.002" from gun to gun, so it is extremely important to correctly size your bore to determine which diameter works best for you. 

To determine which bullet is best for your muzzleloader, start with an empty rifle, remove the breechplug and slide in the .500 bullet. If it slips easily down the bore, you then try the .501 and so on.  When you find the diameter that requires about 20/30 ft./lbs. of force to push down the barrel (that is comparable to the resistance you get loading a standard sabot bullet), you have found the correct size for your rifle.

  1. Great bullets review by Tom R on 10/8/2018

    "Best muzzleloader bullet on the market in my opinion. A quality solid copper Barnes bullet especially when paired with Blackhorn 209 powder provides an accurate hard hitting round and noticeably reduced smoke and fouling when compared with other combinations. Take the time to order the sizing pack to determine the proper diameter for your rifle, replace that nasty pyrodex with Blackhorn powder and enjoy the difference."

  2. Great product, but needs help review by John (Colorado) on 9/25/2018

    "I switched to these bullets from the 245g PowerBelts I used last year. The PowerBelt came apart (think double OO buck) on an elk last year at 60 yards. It killed her immediately, but wasted the off side shoulder. Just finished this season and killed a cow at 30 yards with the Thor. It did amazing on her!! Big exit wound and the bullet didn't come apart. These are the most accurate bullets I have ever shot out of a muzzle loader.
    Now the down side...........If I don't clean between shots, I can't get another bullet down the gun. It is REALLY tight. I'm using the .500 in the gun and due to the fouling, it is almost impossible to get a follow up shot. I would like to hear Thor's reaction and solution to this problem. "

  3. Inconsistent on size review by Chris on 11/20/2017

    "I purchased the sizing pack and the .500 fit perfectly so I order 50 rounds in that size. The problem is that once I took them to the range I found out the sizing was not consistent. 1 in every 6 would fit. Very disappointed. When they did fit they were extremely accurate. Due to the sizing issues I would not order them again. "

  4. Great review by John Bower on 6/14/2017

    "Great company to deal with. Answered all my questions about the Thor bullets and very easy to order them."

  5. kills fast review by rs on 11/27/2016

    "The bullet hit the 9 point Whitetail in the chest came out liver area , left a large hole, the buck bleed out 4 sec. 30 yard at a full run, fell down dead!!!"

  6. Thor bullets review by RS on 8/29/2016

    "This bullet is by far the best bullet i have tested! I live in Colorado so we can't use sabots.

    I have killed many elk with the power belt bullet and i have had to shoot the animal many times because the bullet breaks up , the fragments are all over, and the largest part of the 385 grain bullet has been 185 grains. I was considering going back to my TC Hawkens with a ball. So dead on at 100 yards and 5" low at 150 yards. TC ENCORE , 100 grains rs select Pyrodex. I have changed the 209 primer out for the .25 auto breech plug with 400 cci primers."
