Sight's are very important! When I was young, under 100yrds it was open sights. Now! on my 45-70 Marlin I use a Qick Point, on my 7mag's, one has a 4x12 Leupold, the other has a 6.5x20 Leupold. Everyone has their own personal choice of rifles&sights, these are just mine. Hope this help's.
This is an interesting post I really would like to hunt a real "swamp" like the cyprus bogs of the south....Our "swamps" are a lot different up north...
Some of our cattail bogs and beaver swamps up here are 1/4 mile or more across and my idea of a swamp rifle is a 25-06 or better yet a 6.5-06 with a good scope....Remember that Jack O'conner loved his .270 as his best "brush gun" ...His writings explained that all bullets are deflected by brush and a smaller caliber actually fits through a smaller hole in the brush.....He actually did tests shooting in the brush to "prove" his theory...Only a theory though because brush patches are like snow flakes the are never quite the same!
Good post Bogboy! Jack Oconner was a great champion for the 270. Can't say nothing bad about one, my Dad shot a 270 for as long as I can remember. Like I said earlier, to each his own! If a person prefers a certin caliber, an they are comfortable with it,Great! As far as the swamps an bogs up north,a swamp is a swamp! Just that down here in Louisana, we just happen to have the largest swamp in north America. It's all the same, whatever the person likes,, I'm on his or her side!!!!
