Berger offers 6.5mm boattail bullets from 100 to 140 grains. The 6.5 Rem Mag has a 2.170" case and a 2.805 SAAMI OAL. That's .635" of OAL minus case length. It's got a .261" long neck. Even the shortest 100 grain Berger boatail's shank will extend past the neck shoulder junction of the case if loaded to the SAMMI OAL. There's no law preventing seating that deep, but I wouldn't for both accuracy and safety reasons.
The 6.5 Rem Mag has an identical case length and close to the same case capacity as the 6.5x284 Win which has an excellent record in 1000 yard competition shooting VLD bullets. But the 6.5x284 has a 3.228" SAAMI OAL giving 1.058" OAL minus case length. It's not a short action cartridge.
