[QUOTE="AZShooter, post: 821651, member: 5219"] Nosler most likely chose the more popular bullet weights for the 7mm. Seeing they are called long range no point in making a 150 or lighter bullet as the BC wouldn't really yield high BCs. Perhaps they stopped with 175 gr and didn't make a 180 because some shooters might not get it to stabilize with a factory twisted rifle. (Remington 7mm rem mag barrels use a 1 in 9.25 twist) Berger offers a 168 and 180. I have crunched the numbers of each with the velocities of a 7 STW a while ago and they have very similar wind drifts out to 600 yds or so. Sure the 180 has more energy but the 168 has a flatter trajectory. IMO the 168 LRA might be a better choice with smaller cases like the 7-08 or 284 win and the 175 LRA would be the best choice with a 7mm Rem mag or larger. [/QUOTE]
