I must say Uncle Mike is 100% correct about the .30 being better suited for his property. Couple years ago my dad shot at a nice buck, brush ate the lil .270. Poor deer ran away from him and right to Uncle Mike.... dead buck.
But,Couple years ago I tried to sneak a factory load .30-06 through some brush at a giant. Didn't work out so well. As we all know, bullet construction makes a big difference too. This year the .35 Whelen did just fine going through brush and knocking the deer dead. On the farm fields a .223 works just fine. Oldest nephew came and raided my gun cabinet this year. Borrowed my .223 with Barnes bullets and dropped a doe in her tracks. I had the 6.5 in there for him to use but since he had shot the Mini14 before he felt more comfortable with that rifle....
I've often thought about getting my daughter a .44 mag for up at the cabin and the brush, but now...... I dunno
Enough rambling, came home to firewood stacked inside and the stove roaring. Gotta love a wife that loves wood stove heat!
