A .308 Ruger Ultralite ( way back in early 80s) kicked the snot out of me, only killed one deer with it and 150 Remington Factory load. As Aussie , I too think a 30-30 ( say a really good 3x9 scoped Marlin? is your huckleberry. I had friends use them out to 300yds on a pipeline in East, Texas! I used one for 10 yrs with irons ( but never had an opportunity past 90yds there) Most of mine were under 60yds. A 150 tight behind the shoulder and you are golden. A heavier bolt action 308 ( SPS Varmint) would be easier on recoil, especially with 150s. A .270 with 110 TTSX is very mild to shoot. I used the 7mm Mag with factory 175gr Corlokts and it was not that bad on 90# deer. But a 7mm Mag still kicks. A 300 is "going to kick" with factory loads. A .243 is another great round if you scope it right and shoot it right. Least recoiling of any listed too! Let use know what you decided on Pard, and don't apologize for your pick! smile A free American can choose what they want!
