270 win For Moose

[rbuck]

I am planning on taking my 270 win moose hunting this year, and I have a good load that I use for deer hunting and have so far 2 bang flops. Its quite accurate approx. 1" groups at 100yrds. I am using 140 grain Nosler Accubonds, will these bullets be good enough to drop a moose, I will only have a calf tag.
