Re: 338 edge, 300 rum, 7 rum
Arrow, here's some numbers for you, maybe this will help. The velocities for the 338's are best estimates for what others are running, you may not get this much velocity out of 27". I am getting 2925 to 2950 out of my 27" RUM with the 230. All are 200 yard zero and at sea level, data numbers are at 1000 yards.
300RUM 230 Hybrid Target at 2,925fps: 1809fps and 1672ft lbs. 232.7" of drop.
338RUM 300SMK at 2,750fps: 1676fps and 1873ft lbs. 267.1" of drop.
