This happens to be my caliber of choice I presently own 4 rifles in 7mm-08 with a GA Precision custom on the way. I would not hesitate to take a shot at 350 yards most factory loads have enough energy to take deer at 500 yds. my favorite bullets are Hornady SST 140 gr. and Berger VLD 140. I hope this helps chad
longest shot i have made with model 7, 7mm-08, is 297 yds. dropped in his tracks. when i got to the deer, put range finder back to tree i was in. factory federal premium ammo, loaded with nosler partition, 240grain bullet.
I hunt in thicker cover here in Michigan, so I can't tell you how far the gun will shoot as I haven't had to shoot it over 100 yards for a kill. Love the gun. Love it. Love it. Love it. I have a Nikon Prostaff scope on it and shoot the 140 Corelokt soft points. I've shot six deer with that gun in the last four years--4 of the 6 dropped right in their tracks.
On deer sized game inside of 500yds the 7-08 WILL do anything its larger cousins the 280 and 7mag will do! I LOVE my 7mags and my 280 for sure but my 7-08 is just as capable.
I made a longer shot (for Wisconsin) this year and took my 7 pt buck at 120 yards with no problems whatsoever. The gun is lethal far beyond that distance though.
The only problem was me being so excited that I did not use my shooting mechanics properly and missed once. The buck was kind enough not to move so I shot again using the right mechanics. He did not make it 10 feet before he died.
I own a Browning X-Bolt in 7mm08. It's a great caliber to kill deer with. I use Winchester Ballistic Silvertips to hunt with. They are 140 grain nosler rounds. Absolutely violent rounds.
In my two years using that combination I've taken three bucks that died with one well placed shot. Two dropped with minimal movement, and one somehow managed a 45 yard run after I double lunged it. Granted, I shot him in the back instead of the side like the other two. You take the shooting angle the buck gives you after all.
