I had no pressure signs until 61 at which I noted primers had flattened. I was very pleased with the gains. Accuracy testing wasn't really achievable with the gusty winds but I was well within minute of elk. I'm going to work on it some more but for me this was a really good move. I am very pleased.

For reference I fired one cartridge with the same general setup using 7828ssc and got 2920 for a reading on the crony.



I can't understand why some hate on the outstanding 270 Winchester! That is incredible velocity. In fact, even the 7828 2910 fps is very respectable. I'm not sure there is a better all-around hunting cartridge than the old 270 Winchester!
