Just bit the bullet and traded my Elk Rifle for a new Cooper Mod. 22 in 22-250( knees can't hump the hills anymore ). I love PD shooting and load all of my rds. Got the rifle home and couldn't find any info about bbl twist. I was pretty sure that it was 1-14. Emailed Cooper for details, NOW Cooper makes all of their Std 22-250's in 1-12 twist beginning in 2013! Anyone out there have a new Mod. 22 in 250 with this twist, and what are your pet loads? Cooper advised that they only have 1 load that use for the 250 and that is 37gr H380 pushing a 50gr Sierra BK. Cooper also advised that they have not changed their load since changing bbl twist from 14 to 12. I bought this rifle for shots that my Sako Varmint 75 can't reach! I' thinking with the faster twist, it should shoot the 55 and 60 gr bullets really well? Thanks
 
First, welcome to the Forum!

Secondly, there's no "pet loads". That's a term a writer invented so he would have something to write about. You probably know that but just in case, I mentioned it.

Pick a bullet and work up a good (best) shooting load for it. Write it down, go to another bullet and do the same. Pretty soon you'll figure out which bullet/load your rifle shoots well. Speed is good unless the rifle shoots more accurately at a slower speed. There's not a lot of difference in how many pieces the PD ends up if you think about it.

Give some "benchrest" bullets a try...some rifles are good enough for those to make a showing. Not the benchrest bullets you get at the corner bullet store but rather the handmade dooly's. I don't know who makes 22 bullets these days but somebody will and maybe they'll post...

Hope that new rifle is a good'un!!
 
Cooper Mod 22 22-250

Thanks for that! By pet loads I was referring to people who might have the same gun! I certainly will try multiple loading screen as I have for the last 30 yrs, but more or less was looking for a benchmark! All of the top loading Manuels are showing their loading screen using a 1-14 twist, I know it won't make that much difference with the 12 twist, just thought there would be someone that has a Benchmark for this gun.
 
I've shot everything in my 22-250's. 380 and 414 can give real spikes in pressure, used 4895' 4320, etc, etc, and in 3 guns I am right back to 3031, 33-33 1/2 grains., usually behind a Sierra 55 gr. btsp. In my 40X with the H2 bbl it will shoot into the .3's @ 3815fps. 33grains is the Remington test load.

Well, when you shoot everything over the chrono, you learn you get speed, you get accuracy, but with that powder, you seem to get both. The only pain is that it does'nt meter worth a damn so you have to weigh it.

That said, you really want some fun, get a 20 cal,less powder, recoil, barrel wear, more accurate and far better BC. Don't shoot the 22's or 17's much anymore.

recently told me he is having some great results with a 20 VarTarg in his bench rifle. Getting some fantastic speed and tiny groups with it he sez. Guess I will give mine another look.

Coopers are great rifles BUT

ya gotta wonder who gives them advice on barrel twist rates. Most of what I have seen have made me scratch my head. Guess they must know something the rest of us don't, eh? I wonder if one has the option of twist rate if they order one?

It's easy enough for you to measure the twist rate yourself. with a dry patch, on your jag, push it into the barrel a few inches. Measure the amount of rod sticking out of the action. Mark your rod on top with something. Push the rod in until the mark is again on top. Re-measure the rod and that will tell you the twist rate in inches per revolution.

Folks that buy rifles are not all knowing. A 12 twist barrel will likely stabilize most 22cal bullets...so that's what they do.

For whatever reason there is a propensity for shooters to use a wide range of bullets, particularly heavy ones.
When I was coming of age, everybody used 52-55 gr slugs, lots of guys like 60's these days.
