440: 243 Winchester vs 6mm Remington With Ron Spomer

John McAdams sits down with Ron Spomer to talk about the .243 Winchester and the 6mm Remington (originally the .244 Remington). Both are light recoiling, flat shooting 6mm cartridges introduced in the 1950s and have similar performance on paper at first glance. However, the 243 Winchester remains one of the most popular dual-purpose cartridges in America while the .244/6mm Remington never achieved widespread popularity and is slowly fading away, despite offering slightly better ballistics. Here's the story of what happened.

If you like classic cartridge history, practical hunting ballistics, and straightforward comparisons, this episode is for you.
