as I said in my original post I was just asking if the difference was that big, as lets face it a 22-250 launches a projectile very fast and will stabilise the large weight projectiles quite well provided you have ample twist in your barrel. honestly I have used a 22-250 to varmint to 400 metres (not yards) effectively on small game and would not really consider a 22 caliber effective FULL STOP beyond this range on much other than rabbits, crows or the like. and lets face it a 22-250 is very accurate to this range the only more supposedly accurate rounds are the 22 ppc and 222 with the 223 falling somewhere behind the afforementioned.
does the 22-243 have the ability to load down effectively that the 22-250 does (basically from sub 222 velocities to 4000+ fps) and still stabilise the chosen weight of projectile?
yes I see the velocity potential of what is essentially a 308 necked to 22 caliber just like the 5860 fps I was able to achieve with a 50 bmg necked to 30 cal with a 180 grain projectile, but do you really need it is what I was asking. A 30 cal projectile doing 2800 fps will kill something as dead within effective range as the same projectile doing 5800+ fps with less overall damage at both ends of the rifle. I hear the don"t overheat the barrel and stuff but lets face it that massive amount of powder burning doesn't just affect the barrel it also affects things like the throat of the chamber etc. all of which affect things like accuracy and velocity spread when a cartridge has been trimmed a couple of thou too short or a different brand of brass is used.
Basically what I am saying is that effective range of ANY 22 caliber is restricted, yes you may be able to put holes in paper at a thousand yards with them but I do not consider a 22 a capable calibre at anything further than roughly 400 yards for any game. Lets face it this isn't a forum about shooting targets at a thousand yards it is a forum about long range hunting.
I am sorry if my previous post or this one has offended anyone but I was just asking if there was that noticeable a difference.
