As of today I can state that a .375 H&H spitting Nosler 260 gr Partitions will kill a crow at a distance of approximately 50 yards. Full penetration was managed with a broadside chest shot. Good blood trail and an easy tracking job. It was fun.

Load used: Remington brass, 72.0 grains of Reloader 15, Fed 215 primer, MV approximately 2,750 fps.
I don't think the bullet expanded much.

Good job!! Got any pics? I'd LOVE to see the damage inflicted.. Personally, I'm getting tired of the 'ol 338WM on them. Thanks for the refreshing update.. I've been thinking on moving on up anyhow, and now you have finally convinced me!!

I am going to try the 300 grain Hornady solids next.

Personally i would reserve the solids for follow up shots.
Maybe a pic if you have a mount done!.

300 grain is the go to. Awesome for stopping a charging gopher too. A 300 win mag with a 130 grain speer hollowpoint is great for crows too. Feathers everywhere.

Thanks for the info.....I need to go with a heavier grain in my .270 WSM,the Crows keep getting away from me with little to No blood trail?
