RE: 1,000 yard deer rifle...
I be the first to question the need for a 1000 yard deer rifle. I think the rifle you have built is wonderful, and wonderful for the purpose of target shooting but not deer hunting.
I have been shooting Highpower XC, and Long range competition for years.
Highpower XC is a series of matches from 200 yards standing to 600 yards prone while the long range is a 1000 yard prone match.
I see you have a 6x284....The 6.5X284 was really developed and used quite extensivley by the long range crowd these days in target competition.
Shooting paper and shooting a game animal are two very different things and although I have shot 1000's of rounds at long ranges in competition my personal limits on a game animal is 400 yards.
I am not trying to sound Holier than thou in this, but I urge you not to shoot at deer or any game animal at those distances.
