Re: 300 Rum Vs. 338 Lapua
The differences between the two really come down to what bullets are used in each. I would say in real world situations, it would be very hard to tell a difference between the two of them ballistically at long range.
If we look at the long range bullets in each caliber, given similiar sectional densities and BC values, both rounds are nearly identical in ballistic performance.
Brass quality and strength certainly give the Lapua an advantage but in quality rifles and with quality ammo, not much of a difference to be honest.
Now as far as terminal performance, a 338 will generally hit with more athouraty then a 300 will. That said, there is very little that one will do that the other will not do.
Really comes down to caliber preference to be honest. And to that point, if you compare a 30-338 Lapua to a 300 RUM three is not enough difference to talk about.
Likewise, comparing a 338 Lapua to a 338 Edge(338-300 RUM), they are for all practical purposes, ballistic twins.
