22-6mm imp. or 6.5x284

[coopershooter]

what,s better for long range varminting? low volume shooting. not worried about recoil.
  what cartrige shoots the flattest? and is the most wind resistant.

I have Jap Arisaka chambered for the 6.5-284 an for my gun the best bullet is the Nosler 120gr. ballistic tip. powered by 51gr. IMR 4350 and CCI mag primer. She's a 1500 yard coyote killer!!!!

how fast can you make those 120,s go?

Hi,
I shoot a 6.5x06 close to a 6.5x284. I also shoot a 22-250 AK,IMP close to 22x6mmIMP. I would take the 6.5x06 over the 22-250 AK,IMP for long range shooting any day. The 6.5 does better than the 22 in just about any condition I can think of, except velocity. The22 IMP is good for velocity.

Going back through the archives and found this one I missed while I was in Alaska that that something I think is very importan was missed. When desideing what long range rifle you want to biuld alot of people neglect the most important thing to consider. With a good range finder dropping the first bullet at the proper range is relitive easy, it all science. Where it gets real hard is figuring wind drift. This is the art part. Sure the charts will tell you how far a bullet will drift with a 10 mph wind, but that only works if it`s the same from where you are clear to the target, and it ain`t. The best insurance you can get is to pick a round and a bullet that will give you minium drift. If your guess is off by 50% with a bullet that drifts 12 in you will be off 6 in and still kill your deer. If your off by 50% with a bullet that will drift 60 in you just missed everything. Long heavy bullets at high velosities is the answer, but faster and heaver can go on forever so where do you stop.

It is a balancing act. You have to decide what you want to "make work..."
Last century, with smokeless powder, high velocity became possible. Higher with lighter bullets.

.220 Swift was the "queen bee" for a long time. 48 grain bullet. If it got inside the rib cage and blew up there, it would kill about anything. IF. The bullet might well blow up on a rib or a clod of dirt clinging to the coat... Now we have the .17 Rem exceeding it.

At the other extreme, 6.5 Swede had a long, honored rep for putting a heavy, slow moving bullet thru the guts of large beasts and causing enough disruption, they died....

Last couple decades have been a "meeting of sorts." The first .223 military was twisted 1 in 12 I think, so the 55 grain boat tail bullet would tumble and cause more damage. Before this factory centerfire .224s had been 1 in 14. Wasn't enough. They went to a much longer 62 grain bullet with steel insert and it needed a 1 in 8 twist or 1 in 9 or 1 in 7...

Faster twists wear faster... If you go with a .22-6mm Imp and fast twist and heavy bullets, you can make it shoot, but you will not have the barrel life of a .223. .284 holds about the powder of a .30/'06 case so any of the '06 family records applies. .270 WCF (.27/'06), .25/'06, etc. 6.5/'06 is quite well thought of, just not common when the .270 was so close and factory. .284 case has a great rep for accuracy and one less round in magazine

Your call. LUCK.

I`m getting a .22 - 6 mm built as we speek. I was going to get a .22 - .284 but the smith, who is an avid wildcatter and builds both, assured me I could get 3,500 fps. with an 80 gn. bullet from the .22 - 6mm. A very flat shooter, but more importantly the wind drift will be less than 1/2 of what you get with a .22 - 250. I have very limited loading data for it right now, but it is with some of the powder that I have had very good luck with in the past and should be the right burn rate for this round.

Try data for 5.6x57 should be close to 22x6mm imp.
