Finn enjoyed many rounds, did nice articles on the Swede and 338-06 among many and even one on a NULA in 7BR. I've used all 4, they all work well
Bullet choice + shot placement, always the right recipe.
Yeah, I've had many of the rounds Finn experiemneted with including the 338-06, 7x57, 257 Rob, etc., etc. Finn did enjoy many rounds, but most were to wring out for publication purposes. For his own use, post Africa, he was pretty much a 30-06, then later, 308 guy.
