Ok I am new to this site and frankly I happened upon it because i have questions about long range shooting. I currently hunt with a few calibers, my Favorite is a T/C venture in .270 win. Now for my question, I shoot Horanday 140gr SST Super performance the muzzle velocity is 3096 and 2968Ft lbs of energy. At 700 yards it is 2018fps @ 1266 ft lbs. Alot of guys have been telling me I should go to a 7mm if i wanna shoot distance. Well I looked at a couple ballistic tables and found that what i am shooting is faster and delivers more energy @ 700 yards than, say a Remington 7mm Mag 165gr extended range (1807fps @ 1197 ft lbs). I know these are factory loads and I am sure I could look around and find a more compareable load, but then I also would have to deal with more recoil but have compareable results. So if I am looking for a good rifle that shoots consistently @ 500-750 yards, Would I be fine where I am or should I look to purchase a larger caliber? I use rifle to hunt High country Mule deer. Any advice would be greatly appreciated, I am a complete novice when it comes to this stuff. Just starting to shoot long ranges.
