RE: .243 or .270 which is best for deer
I bought a .244 in 1956, a trade in from a fellah that read and belived all the gunwriter hype about needin' a 100 grain bullet. At the time Remington loaded a 90 Corelokt that killed deer for me like lightining. My Dad took it over when I bought a lefthanded Savage .243 after I got out of the Navy. We continued to load that bullet until Remington discontinued it shortly after renaming their cartridge 6mm.
We both searched for a replacement, he settled on the 85 grain Sierra and used it for every thing he shot at, ground hogs to whitetails. I ended up usin' the 87 grain Hornady inter locked spire point. While the 95/100 grain bullets work ok, they don't get you nothing you can't get by careful bullet placement.
