Re: 6-250 Remington
Your twist rate will be determined by your bullet selection. Varmit rifle or midrange F class?
Berger Bullets web site has a handy quick reference sheet with recommended twist rate for all of their bullets. Very interesting reference source.
My two 6mm/250's are dedicated F Classers and have 30" Kreigers with 1:8 twist for 105 gr Berger VLD's and Lapua 105 Scenar-L's.
I found Lapua 22-250 brass to give me the worst headaches trying to get the donuts out of the necks. Winchester 22-250 was much more forgiving, with little or no donut problems. I may (if they are to be found, anymore) neck down 250 brass and try that the next time I have to form more cases.
With the 105's 32.0 Varget and 36.7 H4350 both perform well, but the H4350 load is near-max in both rifles and I will probably drop that back some. + 25.5 MOA from a 100 yd zero gets you to 1000 yds.
Can't help you with varmit loads, I never tried 'em.

Have you given the XC any thought/considerations??? I just don't think I could give up mine for anything. Great factory brass or of course you can use Win brass like I do for my yote hunting. All I shoot in it are 107SMK's.
Perhaps I am nieve but don't see where the 6/250 would be a better choice with forming cases your only choice????
I chambered up a Douglas 12 tw in XC for giggles to see what it would do with lighter bullets and a shorter FB reamer I had. It easily run the 70TNT's a bit past 3400 with 44gr of H4350. Have never shot anything lighter than the 105/107 in the 8 twist Rock.
Just my .02 cents worth which I have found is usually valued at less than that on this forum anymore!!!!

Re: 6-250 Remington
PJ and Dennis, thank you for the information.
PJ> I read an article at the suggestion of a previous poster on accurateshooter.com about using a modified shell holder and a FL .308 die to push the shoulder back on the 22-250 brass as a way to eliminate the donuts. I think, at your suggestion, I am going to run the 1/8 barrel.
Dennis> I considered the XC because, like you, a couple of my F-class friends are getting amazing results with it accompanied by very little fuss about loading- hit it with a dose of Varget and you are gtg. Only reason I hesitate is that I don't think the XC will cycle through a BDL magazine. I also just want to play with the 6-250. This will be the closest I have ever been to wildcatting and it seems to be a fairly easy one to start with.
Thanks all,
david

Re: 6-250 Remington
Just an FYI David but my brother and I both run regular BDL mags with no issues. I have used mine more as he is still having a hard time parting with his first love, his 243AI that has more than 100 yotes to its record. I have over 700rds through mine now after load devolopment and 4yrs of yote hunting, a couple deer and dropping numerous porky's out of the tops of trees at 3-400yds and they fall like lil treetop snipers on Okinawa many many yrs ago. Absolutely no feeding/cycling issues with all Remington factory parts!
Only difference is he has more money than me so shoots Bergers and Norma brass whereas I so far have used formed Win and 107SMK.
Also possibly less trimming/case stretch as the XC case has way less taper than the factory 22/250 case!!! Probably a moot point for most though.

Re: 6-250 Remington
6mm XC is The Ticket. Enough of a wildcat for anybody, can form cases from .22-250 brass if don't want to buy Norma. Dennis is steering you right.
The better round is the Ackley Improved 6mm/.22-250. 6XC is .001" shorter. Dies are more readily available & cheaper, plus there is the Tubb source for Norma brass.

Re: 6-250 Remington
My take is that in a world where brass is getting ever more difficult to get your hands on, a 6mm-250 makes a lot of sense to me. Resizing its parent brass, 22-250 is stupidly easy and finding 22-250 brass is easier still.
6XC brass and 6.5x47 brass are excellent in their own right. But shortages of these brass are widespread. Who wants sporatic availability of brass or pay for custom prices if it's not absolutely necessary?
Sticking with a 6mm-250 is a more guarenteed way to get to the range.

Re: 6-250 Remington
If you can't make 6XC brass from 22/250 then I don't see where you will have the skills to make 6/250 brass from 22/250 either. Again though I have been told by several here I am lacking in intelligence!!!! Also as I mentioned earlier less brass flow because of less body taper. So in 'tough' times I'll take the XC every time!

That, for all intents and purposes, is the 6mm International. At the time it was conceived (shortly after the .243/244 arms race) it was thought that the 1-10" twist would work the best. However, Remington in an attempt to compensate for their losing the twist race with Winchester started twisting their late 722's in 6mm 1-9". There has been tons of outstanding development in 6mm since the mid-50's.
Anyhow, along came a bunch of 'new wave' cartridges to maximize the heaviest bullets. Some of them dipping as low as 1-7.5". That works, it just limits some flexibility at the upper end.
I would recommend a 1-8" or 1-8.5". If a 1-9" barrel is available it will stabilize 105/107/108's. And you won't lose much, if any, ground with those against 115's in your case.
-good luck with this build. And do keep in touch here about how it goes.
