7-378 Weatherby, Long Range 7mm

A YouTuber, reloading weatherby, has a video mentioning that wratherby may actually put it in their lineup, Looks to me like it would be the equivalent for 7mm that the 6.5-300 is for 6.5mm. Personally with a 28" plus barrel I think it would be fun. That said the 28 nosler strikes the balance bore diameter to power capacity in a 26" plus barrel for me.

The .17-460 eargaspliten loudenboomer was pretty bad on barrels and brass. A fire forming load and a full pressure load then start over with more new brass. And since I am a slow learner we did the next toy with .505 Gibbs brass necked to 17 caliber, great fun but barrel life was under 500 rounds add in that only lathe turned solid slugs could survive it just wasn't cost effective.
