6.5mm. . . .again

They aren't that fast but they retain energy better at long range. the 50BMG has a muzzle velocity of 2700-2800 ft/sec I believe but it is capable of doing what you want way out there, 2Km +. The trade off here is gonna be longer barrel life due to lower velocity.

I do think you are on the right track with the .338 thinking, they are very capable way out there also.And in the Lapua you have components fairly available also.

Gotta remember guys have been shooting .308's up to a mile accurately and having barrels last a very long time compared to some of those whizz zippin smaller cal's with fat cases.

I think that a 6.5-300WSM would be interesting but be hard on barrels, If I had to guess I bet she'd be not much good past 1500 rounds.

Gotta keep those BC's in mind when looking at long range , High BC with a .338 cal bullet would be a dandy in my opinion.

looked a little bit on the net
found that 6.5x300 can touch the 3500fps mark.
didnt look at the 6.5x300 wsm yet.

was looking at 408 chey-tac, 338 lapua, 30-338, they are not THAT fast. look like the clue is the bullet weigh more than the speed.
6.5mm, hard to bring them at 200gr but i found a lapua 155gr, maybe it could be better to shoot a heavy bullet maybe a little slower.
how about a 300wsm neck down to 6.5. . . .slow powder, those 155gr lapua. . . .
and it would be a short action, can be done with a barrel swap on my 10fp if i can be sure the action can hold it. . . .

Look at the highest BC hunting capable bullets and build from there. BC is not everything at long range, but it is one very large part of the retained energy equation and will reduce windrift significantly. The right bullet from a 308 makes it more capable at 1000 yards than a 300 win mag with the wrong bullet. I would be looking for a bullet that has a minimum of a BC of 0.6. That leaves several options available. The 338 Berger hybrid is 0.818...

Ok, I am going to whiz on the fire a bit, i care about ethics but its not my point. Safety is, how can you be reasonably certain someone is not behind that deer at 1.1km?
 
I dont think safety and ethics should be left out of this thread. the way I think of it, if someone has to come on here and ask about equipment for making 1km shots on big game animals, then they should not be attempting it. as well I don't think its good to encourage them.

if you have the skills, knowledge, experience, thousands and thousands invested in equipment, tens of thousands of rounds downrange and at long distance, perfect conditions, safe area to shoot, and the confidence to know that you can make that shot, then I dont have a problem with that. but people that fit that description typically arent on the internet asking what cartridge to use.

I don't know where or what kind of deer you are hunting that you have to shoot from 1km away, why not just grab that 308 and walk 800-900 yards closer and take the shot from a reasonable distance?
 
So, I wasn't out of line bringing ethics into this discussion. I figured a few would agree.

did not see where he asked about ethics, he is asking about a gun that will shoot a deer at 1k .if you think thats wrong start a thread about shooting something that far is wrong in your opinion,dont wreck his thread with your opinion of something he didnt ask.so did any of you become good shooter at long range by not asking or did you all just teach yourself?:eek::confused:
i would look at a 7mm rem mag or 7mmstw with a 180gr berger one of the best co .659 plus they are not bad on barrels
 
Ok lets take the ethics out of this and just look at it a problem of geometry, physics and what is available to do the job. First lets say that to kill a deer we should deliver about 1000 ft/lbs of energy at point of impact. Then lets take one of the highest B.C. 6.5 bullets we can find and run some software and see what we find out. I took a 140 grain berger vld with what my program shows as having a B.C. of 640 (I think that is a little high but lets just go with that for know). My software shows me that I will need to have a muzzle velocity of about 3300 ft/sec to arrive at 1100 yards, AKA 1K with about 1000 ft/lbs. So the real question is how can we get a 6.5 140 grain vld up to 3300 ft/sec and not have a barrel burner? The answer is it can't be done with any conventional equipment available on the market at this time.
Just a note on that even if it could be done here is another problem that would need to over come before you can hit your target. The difference in drop from a target at 1100 yards and one at 1075 yards with that bullet is about 15 or 16 inches. If your range finder say the target (the deer) is at 1100 yards and in fact it is 1075 yards your point of impact will be probably over the deers back. Even if you have it all ranged perfect but you are 1000 feet higher in altitude at your hunting location than your range location you could change you P.O.I.(point of impact) by 6" at 1100 yards.
So if I was asking the question I would word it more like this.
How can I accurately range a deer sized target and delver a 1000 ft/lbs of energy to a 12" target (deer kill zone and I am being generous) at 1100 yards with a 6.5 caliber bullet keeping my chamber pressure below 60,000 psi.
That is really what the question is and as I said as far as I know it can't be done with anything close to normal equipment.

There may not be any stupid questions but there can sure be lot of inquisitive idiots.

If you shoot at a deer standing 100 yards away on a hill,how do you know that there isn't someone standing a 1/2 mile away,behind the hill.If you shoot at a deer 50 yards away towards some brush 500 yards away,how do you know that there isn't someone in that brush?
