I was thinking about rebarreling my Kimber 22-250. I haven't done much research yet on bolt face or other factors. I'm not looking for any thing too wild. Something to shoot out to 500 yards as I am fortunate to have other rifles to extent beyond that distance.
If your a handloader then their are several calibers , the regular 22-250 will get you to 500yds even with factory ammo , My bet would be for a faster twist barrel in either 22-250Ai or 243 Ai. A 1-10 twist 26" in a 22-250Ai will shoot 69gr SMK's out at the 3500fps mark and that bullet at that speed will get you to 500yds easly
Likewise with the 243Ai and a 75gr V-max you will have the same basic effect (major pop on target) at 500yds as you get with the 22-250 at 300yds. and if you get the 243Ai in a 1-8 twist you can shoot the 105gr A-max and that will get you in the 1000yd area.
Personaly I would lean tword the 243Ai hell even the regular 243 , they have better ballistics than the faster 22 and you can get great brass for them , from Lapua and Norma
Another intersting thing I'll put in you head is the 6mm BR , the balistics of that caliber shooting a 55gr V-max still beat most 22's shooting the same bullet and the barrel life is way longer , you can get you chamber cut for the Laupa brass and no case work is needed , just load and shoot. the 6mmBR will get you to 500yds easly with alot of bullet choices and as you probably know its reguarded as one of the most accurate calibers out their.
If 500 yards is your range limits then any modern high performance round could be made to work.
Personally I would look at two rounds. A fast twist 22-250 AI designed around the 80 gr bullets or a fast twist 6-250 for the 105-107 gr bullets.
I have been getting great results from customers with the 6-250, a real pleasure to load for and shoot. Will easily get you 2850 fps with a 107 gr SMK. 2900 fps is even pretty comfortable depending on what barrel length you have.
Very easy on barrels, plenty of long range potential, bucks the wind well, bullets are easy to get, and any VLD or ULD type bullets will work at these velocity ranges so there are no issues with bullet failure. Brass is quality and cheap and recoil is almost not even there in most rifle designs. Just a pleasure to work with.
Quickly becoming my favorite small capacity 6mm round.

What is the case capacity of the 6-250 you speak of? Is there any need to AI it? I as,k because I am back to considering either the 6-250 or a 6 BRX for use in a 500 m rifle. I may have the opportunity to stretch out to 800 yards a time or two, but most (90%) will be from the 500m line.
Kirby has my Savage 12BVSS right now and is putting an 8 twist Broughton chambered in 6-250 on it right now. I wanted a low recoil 1000 yd rifle that was economical to shoot. I was going to go w/a 6BR but the lack of brass forced me to go this route.
I've got close to 400 cases sorted and prepped. I'm chomping @ the bit to try this thing out. In a 15# rifle w/a Holland brake, this thing should have virtually no recoil. I'll be posting my results as soon as I get the rifle back!!!
Kirby recently shipped me a 6mm/250. With nasty weather only have 60 rounds or so through it so far. Even with barrel break-in cleanings, etc. looks to be a great shooter. Most all 5 shot 100 yard groups easily 3/8ths inch, some pushing 1/4 inch - and this with new brass. Heavy rifle with a brake, almost no recoil. Brass easily necked up to 6mm, once through the resizing die and your ready to load em. Easily see the bullets make holes in the paper. Makes for a nice package. Thanks Kirby.
