As stated, a lot depends on the distance. Also how you feel about factory brass. There are a good number of 7mm cartridges, but like all others, powder capacity decides the winners. For factory brass, the 7 ultramag and the 7 STW are excellent choices. The 300 Wby case is very easily necked down to 7mm with one pass thru a 7x300 Wby factory die.Hey there.
I am thinking about building a 7mm long range deer rifle around the 162gn eldx and I was wondering which case would be optimal for that projectile , any help would be appreciated.
