the 7mm tcu is excellant choice with 139 soft point. Its accurate as you can get(probably better then we can aim)
I have it in 14" with red dot on mine and it will kill 10" steel plates at 75 yrds (3/4" thick plates) they jump off the stands at that range. Its low recoil and accuracy make it a good choice for deer sized game. you can load from 100 gr to 168 gr tips
