TLDR: I took some pictures while trying out Thor and No Excuses sizing packs. I was somewhat surprised at the different sizes for different conicals, but it makes sense that lead is easier to squish down the tube.
With the new muzzleloader, I am bound to hunting with full-bore projectiles for my home state of Colorado. I am starting out with the readily available Thor and No Excuses conicals. At some point, I may consider Lehigh or Bull Shop, but I hesitate because they don’t seem as easy to get ordered. Correct me if I’m wrong here and I’ll happily try them out.
I began testing with the sizing pack from Thor bullets. The bullets are color coded (on the base of the conical) and sized .500 (no color), .501 (red), .502 (black), and .503 (blue). The body of the bullet mic’d right at .500 for each bullet. The only size difference I was able to measure was in the skirt at the base of the bullet, which was sized according to color.
Following the directions, I began with the .500 and worked my way up. The .500 started hesitantly with the palm of my hand. Once started, it was easy to push with the ramrod. I noticed there were a few “rough spots” in the barrel which were a little more difficult to push the conical through. I was also able to start the .501 with the palm of my hand. After starting, it required quite a bit of force to push the bullet down the bore. The .502 required pounding on the starter with my palm and resulted in deforming the skirt on the base of the bullet. It was a chore to push this bullet with the ramrod. I was not able to get the .503 started at all. After being run through the bore, the skirt on each measured just under .500.
Seating the .501 felt like more than 20 pounds of force, but it was the one size in between too small and too large. Based upon this test, I will be moving on to the precision testing with the .501 Thor. I wasn’t thrilled that none of the Thor bullets sealed the bore. This picture below is of the light coming through around the .501. I know the design is for the combustion gasses to expand the skirt at the base of the bullet to obturate the bore. Given the relative difficulty of starting these bullets, I wonder to what extent that actually happens.
Next, I tried the No Excuses sizing pack. There was a night and day difference between the effort to seat these and the effort needed to seat the Thor bullets. The No Excuses sizing pack includes 5 conicals, ranging from .500 to .504. The bases are marked 0 through 4. Well, sort of... It is easier to read the marking in this picture than it was to read them with the naked eye. I was disappointed in the obscurity of the markings on this batch.
The bullets were true to size, or they were at least true within the limitations of my cheap caliper. It was 68 degrees F in the house today and the lube on these conicals was already very sticky. I decided to use the calipers to measure these rather than to make a sticky mess out of my Starrett micrometer.
All sizes started easily with my thumb. While each started progressively harder, they were all relatively the same amount of force to seat with the ramrod. When starting the .503 and .504 conicals, there was a noticeable pop-pop-pop as each band of the conical squeezed past the crown. The .504 even showed some signs of lead being shaved off of the conical. The .503 offered a desirable combination of engagement in the rifling, ease of starting, and force to seat. I will be testing the .503 No Excuses conicals for precision.
