There are 7000 grains in a pound. BH209 comes in 10 ounce containers. There are 16 ounces in a pound. So you take 7000grns and divide by 16. This will give you the number of grains in one ounce. The number of grains in one ounce x 10 will give you the number of grains in a jug of BH209.
Example: 7000 divided by 16 = 437.5grns per ounce.
437.5grns x 10 ounces = 4,375grns per jug of BH209
So now you take your favorite load by volume and and weigh it on a scale. 100grns by volume equals 65.6grns by weight. I checked this on two different powder measures.
I will list an example.
You can get 66.69 shots out of a container of BH209 if you shoot 100grns by volume. Thats 4,375grns (10 ounces) divided by 65.6grns by weight.
Cost per shot from Natchez would be $26.99 divided by 65.6 = 41cents per shot.
Of course if you dont live near natchez you will pay a $20.00 bucks hazmat fee. Thats when you get some buddies and order primers, bullets, powder all at one shot. That hazmat fee is a set price for no matter what or how much you order.
Sportsmans wharehouse is selling it for $28.99....$28.99 divided by 65.6= 44cents per shot. When using 100grns by volume, and 65.6grns by weight.
