The Thor™ One Size Fits All 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, one size fits all Thor™ Bullet is the way to go.

**** These bullets are designed to self size to your bore, if your bore is .500" to .503" in diameter. There is no need to order a sizing pack before purchasing these bullets.

  1. Accurate but minimal expansion review by Allen Taylor on 10/29/2019

    "I used this bullet in a CVA Accura with 120 of Blackhorn 209 this year during Colorado’s elk season the shot was 140 yds and the bull went about 40 yds and fell. I found the bullet on the opposite shoulder between the meat and skin. There was almost no deformation to the bullet. It killed cleanly but I think if the shot placement was off any it would not have ended as well. "

  2. Great terminal performance-very consistent grouping review by Paul on 10/8/2019

    "Use these in an older Knight Original Disc 22” barrel converted to bare 209 primers and globe front & rear peep site set up. With 100 gr of BH209 I’m getting consistent MOA or less groupings at 100 yards. I know I could / would tighten up the groups if I had more time but I was really just looking for minute of elk groups in the preseason rush. This past Sept during CO muzzleloader season I took a nice mule deer at 90 yards, off hand shot, dropped him where he stood, complete pass thru. Exit wound was a neat 3” hole.

    I agree with the previous reviewer that these are a tight fit in my Knight Ultra Lite which prefers the .501 size Thors, which BTW also groups the same way with the same charge. "

  3. Bullets shoot consistently accurate at 100 yards using 3 difficult in line muzzleloaders, with several cut the same hole with just peep sights. review by John Kovalchick on 8/9/2019

    "Hunting elk in Colorado with a couple of Knight Muzzleloaders and a Traditions Evolution. The Thor one size fit all shot consistently at 100 yards with a Knight DISC, Knight LK - 93 and a Traditions Evolution, often cutting the same hole and groups of about 1 to 2 inches. The one size fits all eliminates the need to shoot different bullets across different guns and using just peep sight is really quite remarkable to have that kind of accuracy without a scope.....shot approximately 50 rounds and after adjusting the sights was able to get the three guns to group at about 2" high at 100 yards in groups of 1 to 2 inches. Also note that I used Thompson Targets which help out substantially with a "blue" V notch target which gives you a good target at that distance."

  4. Too tight for a Knight review by Buster Brown on 6/14/2018

    "No issues with quality, just letting folks know that the One Size is VERY tight in my Knight Ultralight (which .501 Thor bullets fit best).

    Difficult enough to load (both start and get all the way down the barrel) that they are range use only.

    A sample size of one, but might help someone. If you have time, just order the sizing pack first, find out which fits best and then order that.

    Should work better in the looser bores."

  5. Awesome review by richard snyder on 9/7/2017

    "These are awesome bullets I enjoyed Barnes Muzzleloader bullets Spitfires to Begin with including all centerfire bullets, I am hitting bull's-eyes consistently out of a clean bore cold bore 200-yd with Blackhorn powder 110 grains filled my first 140 in buck in Illinois during their Muzzleloader season at 140 yd straight through the chest dead center it's stuck under the skin mid body on the other side broke 3 ribs it dropped in its tracks recovered 100% of the bullet under the skin on opposite side penetreted over 20"."
