[QUOTE="yobuck, post: 1602768, member: 12443"] Well I wouldn't worry much about the supply, because I wouldn't be using it. To give an example, in the 7x300 WBY case, which is essentially the same capacity as the 7 STW, 90 gr of H870 gave me about 3200 fps with a 30" barrel with a 162 gr. Whereas 79 gr of 7828 adds 200 fps with a 28" using the same bullet. Another thing we found is that the 162s shoot flatter out to 1200 than the 180s. BC is the same as BS without the initial velocity to make it work. [/QUOTE]
