I have been shooting a M70 in .270Win for four years I have used 130gr Nosler AB's and Barnes TTSX's I shot a deer with the TTSX's this year at 300yrd's complete pass through. I wood say for the 130gr bullets max range is probably around 700yrd's for "deer".
the reason I ask about the 7mm rem mag is my buddy got 1 a 700 rem and says it is the best Ive watched him hit plates out at 360Y ran out of room yes the bullistics are great but I done all my hunting in MN so far now it is my time kids are grown up well still got my son he hunts with me to it is time for him to move out of MY mod 94 I like to push to the limits I am perty shure I can hit a 5" out at 300Y my dad taught me vary well he would have me sight in his rifles wish he still had his mouser typo doing the best i can on spelling it burned up in his house o by the way do U think the action woukd be any good to build a rifle out of it
With a 130 Nosler ballistic tip or Sierra game king pushed by 60 grs. H-4831 in a Rem case lit by a CCI-BR2 doing 3150 fps from my Rem. 700 24" barrel with a 3 inch high zero at 100 yards I am right on the money at 300 yards and 8 1/2 inches low at 400 yards. Out to 350 yards I hold in the center of a deers front shoulder and squeeze the trigger. Most of the time the deer is killed in it's tracks.
270 is a nice calibre. I have used it for 4 years now. I have taken 2 bears and lots of deer. I have never not had a complete pass through. This year I took two white tailed does a muley buck and a large black nbear all were drt. I shoot factory ammo . The remington ammo shoot really well out of my gun. If I had the choice though I would buy a 7mm for the increased power and bc.
