[QUOTE="Pdvdh, post: 379914, member: 4191"] I've chronographed extensive load development for my 24 3/8" barreled 7mm Rem Mag and 28" barreled 280 Improved with the same Berger 168 VLD bullets. My MV with maximum, accurate loads for the 7mm Rem Mag is 3050 fps. MV with max loads and good accuracy in the 280 Improved are 2920 to 2950 fps. So the 7mm RM gives me 100 - 130 fps higher MVs in the substantially (3 5/8") shorter barrel. The heavier the bullet, the greater the increase in the MV of the 7mm RM over the 280. [/QUOTE]
