45-82 WCF in the 1886 Winchester lever action rifle

45-82, also known as the 45-90, but because it’s loaded with a 405 grain bullet it’ll only hold 82 gr of black powder. The original 45-90-300, 45-82-405, which was caliber + powder charge + bullet weight, which adds up like 45 caliber 90 g of black powder 300 grain bullet, there was also a 45-85 which was a 350 grain bullet.
This load duplicates original factory load which was about 1420fps.
