Home Forums Reloading Big Game Rifles 7-08 with 168 Berger VLD data

I got to thinking today about the velocity of 7 mm 150 gr and 168 gr bullet running in the 2600-2800 FPS range.

I built a 357 rimless (.223 basic brass cut at 1.8”) pushing a 180 gr .358 bullet at 2600 FPS and 150 Gr. At 2870 FPS with no where near the case capacity of the bottle necked case of the 7-08. I know the 358 bullet does not babe the bc or long range trajectory but the powder is still pushing the weight.

Why?
