I'm looking for a long range target rifle

[MCMXI]

I have three Accuracy International rifles. They're chambered in 6.5 Creedmoor (.308 Win), .300 Win Mag and .338 LM. Despite all three rifles consistently producing 5 to 10-shot groups in the 0.2 to 0.3 moa range at 100 yards, and despite all of the opinions on which is more accurate or easier to shoot at 1000 yards +, I find the .338 LM the most consistent in a wide variety of conditions. I have an 18" round steel target at my house that is 1050 yards from my back door and it's kind of easy to hit it with the .338 LM. At that range the 6.5 has a little less drop but a little more wind drift. There's something special about the .338 LM that transcends ballistic tables, recoil calculators and opinion.

With the right powder (usually H4350), the 139 - 142gr bullets were capable of 2800fps easily while staying within SAAMI pressure specs.

I'm shooting 140gr A-MAX (ELD Match) at 2,900 fps from my 6.5 Creedmoor with pressure around 59,000 psi.

Anyone thinking of getting into long range precision shooting should read Bryan Litz's book, particularly if you plan on shooting at locations other than square ranges with 6 foot square targets, target pullers and flags all over the place. Pay special attention to his discussion of deterministic and non-deterministic variables and the myth of "reading the wind". When you miss an moa target at 1000 yards and have no idea if you missed high, low, left or right you're in the real world.

How about the Ruger precision rifle in .243? Its got a fast twist barrel and would make a great long range gun.
