I know what some of you might think about me running my 1-14's hot & fast but I bought the 22-250 & 220 Swift's for speed & all I can get from them. When I want something less, 3100-3200 fps, I'll drag out my 222 or 223. If I burn the barrel so be it, I'll buy a new Pac-Nor or Bartlein & stick on them. I did just buy a new Cooper Phoenix M54 22-250 1-14 twist 26" in the new HS Precision stock and this one I might baby just a little. It's beautiful, 26" heavy barrel & the stock black with lots of blue webbing. Good shooting to you nice fellows whatever twist you decide on.

I would never run a twist faster than a 12 on a swift or a 22 250 but man are my 12's easy to load for. It took me about 250 rounds and a bed job to get my 700 vs swift to settle in at .5 or .6 ish with 5 shot groups of 55 bt's but I do have good loads for about 5 different bullets from 40 to 55 grains for it. It is good with factory hornady 55s as well. My vsf swift still isn't as good but will do pretty close with 55 Nosler SHOTS.
I have a varmint special ,an lvsf, and a bdl in 22-250 and none of them will shoot factory hornady 55s or white box 45's worth a hoot. 40 vmax with 36.5 varget at 2.350" with a cci 200 is great though.
I put together a 14 twist Savage swift with a new 112j take off and it is not good with anything lol.
It sounds like a chronograph would be an excellent investment for you.
I own a couple of 22-250 rifles that seem to like the 45 grain WW White Box stuff. Nothing spectacular, but I also have two 22-250 rifles that don't shoot the 45 grain WW promotional White Box ammo. But all of the same rifles shoot better grade factory ammo as well as handloads with 52-55 grain bullets "extremely well". Go figure. I doubt that twist rate has anything to do with it.
