      You really should compare the 250 gr Badlands SICBM in the 338LM to the Berger 230 in the 300NM. The 250 can be pushed at 3050 fps with a higher BC than the Berger, making the 300LM look like a BB gun.

      Hi Ryan,
      Thanks for the read. I have your book. It’s great.
      Could you elaborate on the politics of AI?
      Thanks

      The 230 grains in 30 caliber has a sectional density of .3464. The 250 grains bullet has a sectional density of .3126 and a lower ballistic coefficient than the 30 caliber bullet you use to illustrate your example. This is not an apples to apples comparison. Not even close since the Lapua can use a 300 grains bullet and a 250 grains bullet in .338 caliber is really equivalent to a 208 bullet in 30 caliber. See where I’m getting ?

      In order to make an apples to apples comparison, the .338 caliber bullet should have the same sectional density…That bullet would have to weigh 276 grains…Anything between 275 and 280 grains is fine for comparison’s sake. These heavier bullets can be pushed at over 2800 fps and have exceptionally high ballistic coefficients. They beat the 300 Norma on all counts at all ranges except for recoil. If your interest is to portray the practical efficient side, then the comparison you use is acceptable but only in illustrating recoil, far from it in total capability. It is easy to view your article as biased in favor of the 300 Norma Mag, not to take anything away from its practicality and usefulness, the 338 Lapua is still a far superior round. More pertinent information is needed in order for your article to provide good comparative and informative values. As a writer, you are obligated to provide sound information, not incomplete biased information.

        My post isn’t to take anything away from your other accomplishments which are clearly shown by your credentials nor is it to ignore the most commonly used weights in these two calibers. It does seem to me that the 300 Norma mag, being a new round is heavily marketed at the expense of its competitors true qualities which should be present in an article discussing or comparing them to others. I read far too many articles boasting of “better” ballistics between one or another, usually the 7mm VS the 30 Cal. They’re mostly all done in the same vein and the bullets they use are a far cry from an apples to apples comparison and one wonders why…

      Lol, I’ll stick with the 338 lapua. Sold the norma. Might want to do an equal comparison. Stating it is meant to shoot heavier bullets depends on the application.

      It’s sort of like saying, “Hey guys, let’s give up the 300 win mag for the 6.5 creed for our sniper platform. Lol

      Be a man and take the recoil or put on your wife’s muzzle break. If you don’t know how to handle the recoil, you probably should have the weapon your shooting.
