If I was going to shoot whitetail at 800 yards, I would look into 7 mag or maybe play with some 30-06 loads. I am partial to 25-06 and there are some light bullets for that. Would be a light shooter. But you would be back at a more or less 220 swift territory.

P.O. Ackley noted that his experience proved that a .220 Swift was the most deadly caliber ever produced for deer and similar-sized game. In addition to some extensive shooting tests on animals, findings by firing two 48-grain bullets from a 220 Swift into half-inch armor plate on the front of a U.S. Army half-track. He also fired 100-grain bullets from a .270 Winchester and armor-piercing rounds from a government .30-06.

The results were amazing. Both of the .220 Swift factory loads penetrated completely through the half-inch armor plate, leaving holes approximately 3⁄8 inch in diameter. The 100-grain .270 bullets managed no penetration whatsoever, leaving only shiny spots on the armor plate, and the .30-06 armor-piercing bullets made only shallow craters.

He made shots on a conservation hunt to reduce the number of wild burros in excess of 600 yards. Even the gut shot burros dropped in their tracks.. Amazing little caliber, it's not for every thing, but man it can do a lot. I was summarily impressed.

220 swift.
Bolt.
Bull.
We may have had this disscusion.

I don't think that's the kind of details he wanted.

Do you load your own or factory ammo?

Depends what you want to do with it, long range cam mean different things.

Already have my 220 swift, spot on for a great shooter gun.

Just really looking at something out of the ordinary that will be an easy shooter that can hunt white tail and below with. Bench rest on steel to 6-800 yards maybe.

6.5 creedmoor is a very cool round and proven at long range. A 6.5-284 or 6.5-06 would be fun to play with though since you roll your own

I like your line of thinking. The OP mentioned unique, and I have a 257 STW that I would not trade for anything. It's built on a Remmy 700 action with a Bartlett bbl. I would not hesitate on a Shillen bbl either.

Neighbor has a neat set up. Sako action Shillen 26" heavy barrel chambered in .25/284. I think you would be kinda limited on bullet weights but extremely accurate.

where will you take an 800 yard shot?

Defiance or Surgeon action

Bartlein Match barrel

Jewel HVR trigger

Caliber and stock are up to you, Amigo.

I built a .260 Remington (still hate that name - should be a 6.5-08 A-Square) this year that's turning into a real shooter. I did have to laugh at myself last Sunday when I killed the first deer with it. I shot a doe at 85 yards and used a 14 lb target rifle with a $2500 scope. Talk about a no drama shot!
