Thor Bullets Sizing Instructions
What are Thor bullets made of?
Thor bullets are 100% copper.
Do Thor bullets have a lead core?
No, Thor bullets are made of 100% copper.
What if my sizing bullet doesn’t leave rifling marks?
Rifling marks are not necessarily an indicator of bullet fit. If the bullet loads well, but doesn’t leave any rifling marks, then it should still work great. Use your discretion when sizing.
What if my sizing bullet uses less than 10 pounds of pressure to load?
As long as your bullet doesn’t ‘free fall’ down the barrel, then it should be the proper fit! Keep in mind that subsequent bullets will load even tighter after powder fouling.
How do I know what 10-30lbs of pressure feels like, as stated on my sizing pack instructions?
10-30 lbs of pressure should feel like you are loading a saboted bullet (bullet with plastic gas seal). This is a general range of force that we recommend. You may find that your bullet loads with less than 10 lbs or more than 30 lbs of force. We recommend that you choose what feels good for you. As long as your bullet has ‘some’ force when loading it should be able to engage the barrel and give you the proper gas seal.
What if the .500” sizing bullet is too tight?
If the .500” sizing bullet is too tight for your barrel, we do offer a .499” option that will fit your bore! The .499” diameter Hammer Bullets are only available through Thorbullets.com.
What if one sizing bullet feels too loose and the next sizing bullet feels too tight? What if I am ‘in-between’ diameters?
We recommend choosing the size of the looser fitting diameter bullet. As long as your bullet doesn’t ‘free fall’ down the barrel, then it should be able to engage the barrel and give you the proper gas seal. Keep in mind that subsequent bullets will load even tighter after powder fouling.
Are Thor Hammer bullets available in half-sizes?
No, Thor bullets are only available in .499”, .500”, .501”, .502”, .503” & One-Size Bullets only.
What Thor Bullets are recommended for elk-sized game?
We recommend 297 or 300-grain bullets for elk-sized game and for longer ranged shots.
What Thor Bullets are recommended for deer-sized game?
We recommend 247 or 250-grain bullets for deer-sized game, including mule deer and whitetail deer. (The 297-grain and 300-grain bullets will still perform great as well)

Can I use Thor bullets in a smokeless muzzleloader?
Yes, you can use Thor bullets in a smokeless muzzleloader.
Do Thor bullets need to be lubed?
No, Thor bullets do not need to be lubed and we do not recommend that you lube them.
How often do I need to clean between shots?
While we recommend cleaning between each shot, you will ultimately have to find your own routine. If a follow up shot is difficult to load, then you should probably swab and clean the barrel. For example, if your third shot is hard to load, then clean after every second shot. NOTE: Some powders or propellants may be cleaner burning than others.
Why does my Thor bullet sizing pack have different colors than what it says on the sizing video?
We updated the Thor Bullet Sizing Pack colors a few years back to the following:
- Colorless - .500”
- Green - .501”
- Black - .502”
- Blue - .503”
Early videos and instructions did feature a ‘Red’ bullet, that has been swapped out for the new ‘Green’ color.
I received a bullet that is rattling?
The rattling is a byproduct of the manufacturing process that does occur from time to time. Through extensive testing, these bullets will perform and group the same and may be a few grains heavier.
What if I cannot find a diameter or style that fits my rifle?
It is extremely rare to find a muzzleloader that doesn’t work well with Thor bullets. We are committed to helping you find the correct diameter bullet that works for your muzzleloader. However, in the event that it does happen, please let us know and we can assist you with a return.
