New Barrel?
I just sighted in my new Rem 700 22-250 SPS. Love it. Its everything I thought it would be. 400yds, effortless. Almost too easy. I have not tried to go out further yet. It has a 1-14 twist and I think I need more like a 1-12 or faster so I can send heavier bullets further down range with more stability and to carry more energy to get the job done. I reload .55gr. Hornady and 55gr. Nosler . I would like a 60gr. or heavier (if I can find them). So I would like some advise on what my options may be. Any suggestions?

I would like to go out to 800yds and beyond and take out Yotes. I know there are a lot of factors to contend with for yardage like that but that is my goal. Do I contact Remington for the new barrel or do I get one from another manufacturer? I have a bull barrel on it now and want to get one with a faster twist. As far as what its worth......money wise? I spent $600 on the rifle, $400 on the optices and planned on at least $300 for a new barrel. If I can make a shot at 1000yds. (my goal) That accomplishment is priceless. Thanks for the advise.

listen to whatever RR says. As far as barrels, Krieger, Hart, Pac-nor, Montana, Shilen, Douglas, Macgowen, Broughtan, Lother Walther all make good barrels. Shilen, Douglas, Macgowen and LW can all be had for around $300. I just ordered a shilen ss select match threaded and chambered for a savage action for $269.

I'm in total awe when I hear guys talk about shooting at such long distances. Although I wish I did, I do not possess the skills required to hit a target past about 250 yards. I know that anything is possible, but I was under the impression that .224 caliber bullets are at a disadvantage beyond 500 yards, regardless of the initial velocity. Keep us informed how this works. As far as which barrel to use, when I worked for Knight Armament we used barrels from Boots Obermeyer in our sniper rifles. He uses 5R canted land rifling in his barrels, and each one is hand lapped.

Y are you doing this with a .224 caliber? You'd be better off with something at least a little bigger. Are you just doing general varmint hunting or you shooting for fur? at 800yrds you are basically hitting the yote with a .22, and if you start asking people about that there are very mixed views.

i agree, i have the same rifle, ive just tinkered with it (look back a few posts, titled I finally got it, or something like that, and while i love the .22-250 caliber, id never attempt to kill past 600yds, if you were gonna rebarrel it id say do it in ATLEAST .243, but if i were to pick a caliber (which im gonna rebarrel in) it would be .308. they dont have as good a velocity, but as for ke at further ranges, it blows a .22-250 out of the water

im really impressed with the performance i get from my broughton 5c barrel, but i wish i had got it in something longer then 26 inches. but from a 26 inch barrel i can get speeds that are about 75 fps + faster then they should be, and from what ive been told its because of the 5c rifling (canted rifling, very similar to 5r that remington often uses on there 40x barrels)

I understand that at extended ranges, a .55gr bullet lacks the energy to take an ethical shot. Thats why I would like to push the heaviest bullet possible with my rifle. In order to do that, I need a faster twist. I have a Rem 700 30.06 BDL and with a 110gr. bullet, I can get out pretty far. Its just that the 30.06 drops so fast that its hard to adjust for wind and compinsate for bullet drop. The 22-250 shoots flatter and faster, so, this is the reason why I am inquiring about long range shooting with a lighter caliber. I may never replace the barrel, I may go with a larger bore in time but for now, I would like see what is neededto push my 22-250 to the limit. Thanks for all the advise.

22 Caliber
You are on the right track.
For 600-800 yard shots the 22-250 with the 75 grain A-Max is the perfect choice. I put a Krieger barrel on my 22-250. I asked the tech at Krieger for the optimum twist rate for the 75 grain A-Max, and he recommended a 1in8 twist. That is from the man himself at Krieger, so I trust him.
Now some people say go with a 243 or 6 mm cartridge. That is a bad idea and here is why. First of all the 75 grain A-Max has a substantially better Ballistic Coeffiecent over the 75 grain 243 bullet. And since both bullets start off at about the same velocity(3300-3500 fps) the higher BC makes the 75 grain in the 22-250 a vastly superior choice with better down range ballistics. The sectional density is not as good as the 243's bullets, however we are talking varmints, not grizzlies.
You have to go with the heavies in the 243 to get close to the BC of the 75 grain a-Max in the 22 caliber. And then your velocity drops down to 2900-3000 fps. Check the drop and drift of a 22-250 at 3350 fps with a high BC 75 grain A-Max as compared to a 105 grain 243 bullet at 2900 or even 3000 fps. You will be suprised.
Then the next comparison needs to be controllable recoil. It is much easier to control a 22-250 than a 243 in the field to see impacts.
I wanted to put together the best long range varminter I could for long range shots(out to 1000), and still see impacts. I did a lot of research and came up with the 75 grain pill in the 22-250 as optimal when comparing all factors.
Further proof of this is just look what the militarty did. They have stepped up to a 70 grain pill for their new and more effective rifles. Because of the down range ballistics.
Ballistic Coefficient for 22 caliber 75 grain bullet(Hornady)---.440
Ballistic Coefficient for 243 caliber 75 grain bullet(Hornady)---.330
That is a big difference. Tom.
PS: For the guys advocating the 243 over the 22-250. I just ran a ballistics calculator on the 22-250 with the 75 grain bullet and the 243 with the 75 grain bullet. At 800 yards the 22-250 retains 530 ft/lb of energy. The 243 with a 75 grain bullet retains 326 ft/lb of energy. So which bullet is carrying more down range punch?? IMO it is the 75 grain in the 22-250. You have to go to a 100 grain bullet to get that power in a 243.

PF,
even with the 22/250/75gr. amax@3350 sighted dead on at 300 you'll be 222" low at 1K, you'll need a repeatable scope to be able to dial in and alot or preparatory work in establishing and tweaking your drop chart to allow first round hits on game that far.
To 700 yards things work out pretty well, beyond that you need a way of knowing your current atmospheric conditions. Temp and bar pressure are the big ones here
Bar pressure effectively changes the bullets BC, enough so that a big swing in BP can changed your point of impact by 5 ft at 1000 yards.
My LR varminter is chambered in 6.5 Gibbs, it runs a 140 gr berger (BC .7) at 3340 fps and its -160" at 1K.

What you say is quite true. However very few people consider a 6.5 Gibbs as a true varmint rifle. I am not saying you are wrong, because you are not wrong. However you are not comparing apples to apples. You are comparing apples to watermelons.
I have no trouble dialing my 22-250 into 700 yards right now. I will be working on the 800 and maybe even the 900 yard targets this winter for next ground hog season.
There is no doubt it takes time and quality equipment to do this. As I am sure you well know. However the 22-250 with the 75 grain A-Max in a fine tuned rifle is fully capable of doing this.
Ridge Runner I respect your abilities so please do not take my comments here as disprespectful-I do not mean them to be. I am only pointing out that the 22-250 is capable of a lot more than a lot of people think. Tom.
