Like., 300 Norma vs. 338 Lapua – Velocity The same speed with different weight bullets is why you see the difference in energy of the two rounds. Up close, the 338 Lapua has 10% more energy than the 300 Norma., Even drop and drift are reasonably similar, so unless you're trying to pick nits, I will take any one one of three. I use the Berger 215 gr. for the .300 Norma Mag and either the Berger 250 gr. or 300 gr. for the .338's, all three with 27" barrels. Flip a coin but go out and have a great time in the field!, You can see a huge range of cartridges, including the 338 Lapua Mag, and precision cartridges like the 6.5 Creedmoor, 6 Creedmoor, and 6.5×47 Lapua, and larger cartridges like a 7mm Rem Mag, 6.5-284, and even the 28 Nosler. But, 5 cartridges seemed to be most popular, with several people using each of these: 6.5 PRC. 300 Norma Mag. …, You can see a huge range of cartridges, including the 338 Lapua Mag, and precision cartridges like the 6.5 Creedmoor, 6 Creedmoor, and 6.5×47 Lapua, and larger cartridges like a 7mm Rem Mag, 6.5-284, and even the 28 Nosler.

All can be very accurate, I don't believe any one round has a advantage for accuracy,that is all about the rifle and the shooter.My COL is 3.890 on my Edge and it runs 300 SMK's at 2867 comfortably with RL25.
