Earlier I said this was a box of 115 grain HTPs. I was wrong, they were 147 grain HTPs.
This is the semi-jacketed round:
Total cartridge weight: 190.5 grains
Bullet weight: 125.2 grains
Powder charge: 5.3 grains
This is the usual HTP round:
Total cartridge weight: 212.4 grains
Bullet weight: 147.8 grains
Powder charge: 3.3 grains
I checked and rechecked my Lyman 1200 after weighing the HTP round. Then I thought to look at the box again and sure enough, they are 147 grain (ish) bullets NOT 115.
The difference in powder charge has me scratching my head as well.
I can imagine a disgruntled employee randomly mixing up components, but who knows!
