Daryl:
My friend with the new Marlin (Ruger?) .45-70 was using Barnes premium ammo, presumably thrown in with the deal, and Federal factory loads for backup.
Should have paid more attention: the Barnes had pointy red polymer tips iirc.
He had already knocked over a couple of young buff for the chiller on a previous hunt, using that ammo.
Hopefully he will start keeping the empties so we can load him up some 350gr Woodleigh Weldcores for buff and big boars.

I have developed a load for the Baikal double-rifle that emulates .450 nitro-for-black all day long!
