The Thor™ Bullet produced by OPG Gun Ventures is a patented, full bore diameter, bullet conical that is bore size specific. The .50 caliber, ballistic tip, Thor™ Bullet is Colorado legal, which has some of harshest regulations for muzzleloader projectiles. With 100% copper construction, the bullet is also certified legal non-lead in California. The Thor™ Bullets are built on a limited basis, and are manufactured by Barnes™ using their X Bullet® Technology of all copper construction with expansion technology of an integrated expansion ring specifically designed for loading and accuracy. The Thor™ Bullet is proven to be extremely accurate at longer 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 grain 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, 300 grain Thor™ Bullet is the way to go.

**** Before purchasing your first pack of Thor™ Bullets, you 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), then that’s the correct size for your rifle.

Great round

Very unique round with the hollow base that slightly increases the engagement to the rifling. A bit pricey and doesn't come in larger bore sizes for the Savage 10 ml2. Need to offer .504s as well otherwise great round.

Great bullets and shoot even better. Going to be my elk bullet this fall

Moose Killer

I used the Thor Hammer .50 cal in 300 grain with 77 grains of Blackhorn powder in my CVA Accura..
I shot the moose at 65 yards with a double lung shot. The moose ran about 150 yards and dropped dead. I was never able to retrieve the bullet as it went completely through the animal leaving a great exit wound.

I CO we can only use iron sites. Off the bench I was getting 2 inch groups at 75 yards. I suspect it would be much better with a scope as I could barely see the bullseye at that distance.

Customer service as always second to none! Originally ordered the .500 based off the sizing pack, item was much too loose for my specific bore sent a quick email they had the .501 bullets shipped the very next day no questions asked. Outstanding customer service! Thank you

Awesome bullets

They perform as advertised. I can always see the consistent expansion through the deer I have taken. I have only recovered one projectile so far but it looked exactly like the picture on the box, perfect expansion and it weighed 296 grains on my scale. The only part missing was the blue tip.
