i had initially thought about going with the 22-6mm myself. loaded with an 80gr. a-max and velocities of up 3750fps. (even though a velocity of around 3400-3500fps sounds more realistic to me). A 22-250 ai with a fast twist would come very close to this. 80gr. .224 bullets are very long though and with a 6mm case i would of had feeding problems in my rem. sa. My howa with a 1-12 twist shoots the 45grainers like no ones buisness at 3800fps. So my 22-250 is just fine for me. With that said i have decided that for something a little bigger than a litter bigger bullet is needed.

An 87gr. .243 diameter bullet is almost as good.

.224 dia. bc/sd
75gr. a-max .435/.214
80gr. a-max .453/.228

.243 dia. bc/sd
87gr. v-max .400/.210

keep in mind bc is a measure of how well a bullet flies through the air and sd is the mesure of a bullets abillity to penetrate. That may not mean a whole lot until you start to consider terminal ballistics. I believe that a larger dia. bullet will create a bigger wound channel. (not gonna say shock or shock wave here cause i dont believe an animals insides behave like a gal of water when shot) Thus be a better choice for real long shots when the bullet may not fragment like it should especially when shooting an 75-80 gr. a-max out of a .224 cal.(these are the heviest bullets with the highest bc for .224) Also these bullets were intended for targets and deer sized game.(.224 TTh(22-6mm)) and from what i've read on this site an 87gr. v-max outta a .243 or 6mm works good on both yotes and deer.

I would have to say 6br...too many reasons to list all but they are absolutely amazing with a fast twist and an accurate platform.....

I hope your not looking to save the fur, anything with enough horse power to get you out to over 500 is going to be pure hell on a pelt. There have been a dozen good answers stated as to calibers to get you out that far but what about just doing something simple? get you a Savage rifle in 243 with a 1-8 twist barrel and shoot the 105 A-Maxes, it may not push the bullet to 3500fps but I have figured out the VLD type bullets travel a long way without having to be blasted out the barrel at crazy velocities found out shooting praire dogs with a 223 and the 75gr A-Max bulletshold over like i was with the 55's and the goofy bullets would hit way past the little critters. The 6x47 Lapua sounds like a very promissing round and the 6BR has proven itself, I've heard many good things about the 22-243 and the 75gr A-Max but barrel life has not been a good seller. I have just started the long range with the 243 and 105 A-Max but so far it's looking promissing but the jury is still out. If you do go with a Savage and you don't like the caliber just chuck it up in the vice take your handy barrel nut wrench and in 30 minutes you can have another rifle. Later,

You sound like me many years ago when I was building my first custom (non-competition rig).... I could not decide on the exact caliber much less the chambering for that caliber. I wound up with 22-6mm, 6x284, 25x284, 6.5x284. If I had to do it all over again, I would do the three barrel switch gun and leave out the 6.5x284. I have never even shot the 6.5 or .25 barrel. I just cannot fathom having any more fun than playing with the 22-6MM and the 6x284. The 284 case is really not that bad on barrels if you don't let them get hot and continue shooting like a machine gun (I have over 2000 rounds on mine at 3700 fps with 90 BT and it still shoots bug holes). If you are going to shoot it fast with a lot of follow up type shots, then a BR case and/or variation thereof will give you better barrel life. But, for shots on animals with cold barrels the best I could recomment is the 6x284 and 22-6mm.

For gentlemen shooting (minimal recoil to see the impacts) in a non-hunting setting, I would say the BR or the BR improved type chamberings. They are fun to shoot and you will enjoy yourself. FWIW, I am getting ready to have a new 8 twist barrel chambered in 6x284 next week so I can shoot the longer bullets (i.e., 90 sciroccos, 107 Sierras and eqivalent Bergers).

One more point...... A custom action and the customized factory actions are about the same investment. The best would be to purchase a used custom action which will usually get you under a tuned factory action. And,,,,, you will probably be much happier with the custom action.

Good Luck,

Hoghead, I have a 22-250 remington vssf no customization. It shoots one-ragged-hole 10-shot groups at 100yds with factory hornady ammo, 50gr v-max. Recoil is very light, I have no difficulty following through and spotting my own bullet impacts. When the barrel finally gives out I'll re-barrel with something heavier and a faster twist. But I still wouldn't recommend that anyone buy a factory 22-250 and customize it just to be able to shoot heavier bullets. The real strengths of the 22-250, 220 swift and other hot 22 varmint cartridges is in their long PBR. For the shooter that wants to shoot out to 300-400yds without having to be overly concerned about compensating for windage and elevation these cartridges are almost without peer.

you asked for opinions you got it. verry good ones too. Post 32 says it all. my coyote rifle is a sako 591 chambered in 6-284 28 in verry light bbl it is just a coyote gun gets carried more than shot. if you go to a prerry dog town with a 6-284 you will go home with a shot out bbl. my pardner knows first hand. when its windy i use 6mm-250 basicly same as 6 xc ,calm days 223 or 223 imp 22-250 i just put togather a 6,5-284 with 30in bbl this may be the one.?
