Congratulations! You will like the 7-30. I have been shooting two different contenders in 7-30 for about 10 yrs now. I like the 120grn Nosler BT best but have used the 139 Hornady SST also for bigger game like big deer and hogs.
I have taken 4 deer with the 120 grn bullets and they do well. They are easy to load also. 30-30 brass is plentiful.
Good luck on your venture for deer.
Mike
