RE: 7MM Rem Mag shells
Any controled expansion bullet in 150 grains is all you will ever need to use from deerto moose. Accubond, Interbond, TBBC, Partition, etc...
You could even go lighter with the Barnes, Winchester XP3, The new Nosler E-tip, and Hornady's new all copper bullet in 140 grain weights.
Me personallyI would pick one bullet that will do the job well on both animals rather than using two different bullets for each animal.
