In 2012 I did a bullet test with a .45-70 using 300 gr JHP Hornadys and 300 gr Nosler Partitions. I also tested 220 gr and 270 gr bullets in 375JDJ. It was a pretty tough test using particle board, catalogs and water jugs. Of coarse the Partition did well but the 300 gr Hornady really impressed me. People always talk about it being good for deer sized game but I think it would work on larger game too. It outperformed the 270 gr 375JDJ bullet which has been used to take some very large game. I still haven't taken anything with a .45-70 (other than a snowshoe hare with a 405 gr bullet using a Marlin 1895). I'll practice with it all summer and plan to use it but when season rolls around I'm usually in the mood for a revolver or a muzzleloader.

The test was done using my 12" .45-70 Encore barrel. For some reason the link doesn't show the inch symbol (") now. All the numbers listing the thickness of catalogs/particle board used and amount of penetration were in inches.

Here's a link to the test I did.
