So Iíve got my 204 AI, and I love that thing. Itís a screamer, and shoots lights out.

But this morning, I took advantage of buying a Rem 700 in a 22-250 with a shot out barrel.

Im sure you can prolly see where this is going.. But I canít take it any longer. Iíve had the 20-250 bug for a couple years now. So when I found that rifle this morning I couldnít get there fast enough to get it bought.

I may totally fail at this, but Iím hands down going to give it all Iíve got. I was just hoping someone here, has been around one or messed with one personally. My dad, Andy Laughlin, said he thought that maybe DAA had one.

My main questions are barrel length and bullet selection.

My goal is not to push big heavy bullets, Im looking at 50gr MAX bullet weight. Iíd like to stay around the 40-45gr range if possible. I was thinking about a 24Ē-26Ē Lija or Shilen barrel in 1:14 or 1:16 maybe.

Iíll have the action trued and bedded. Most likely a Jewel trigger because thatís what I run in every rifle, other than Iíve real been thinking about trying out a Timney. Yadda Yadda Yadda, the rifle will get the works.

I just need some help and advice on bullet and barrel length selection.

Any help with this is greatly appreciated guys. Thanks!

In a 20 cal, 40 grainers I'd go no less than 1-11 twist. There is no 50 gr vmax.

Sounds like a neat project. I'd be thinking 40 gr Bib bullets.

Unless your set on one of the barrels you mentioned, PacNor makes a great barrel as well. With all new tooling in their shop it might be worth a look.

Iíll definitely do that then, I was just rough guessing on what twist I would need with light bullets at the insane speed Iím planning on. I didnít want the rotation making the bullet come apart obviously. Iíll take all the help I can get, so Iíll definitely do that.

And I meant 50gr max bullet weight, not as in the Vmax or Amax bullets. I seen where that sounded kind of confusing so I changed my post a little. I apologize for that.

Not cartridge related, but.....

I've had more than my share of big, fat, long, heavy barrels.....

On a packing, carrying, hunting, calling gun, anymore, I refuse to build with anything bigger than a regular #3 sporter contour barrel, & 24" max length, with 22-23" preferred.

I believe DAA might have have played with a 20-250.

Yup, I have one. Built it about 15 years ago. Neat rig.

I had a 20-250 built on a trued SA Rem 700 a couple years ago but I only ever intended to shoot the Berger 55's so mine wears a Krieger 8tw finished at 26. I'm using necked down Lapua 22-250 brass and RL16 with those Berger 55's and it shoots them really well.

If you only plan to shoot 40-45gr bullets at the heaviest a 10tw is what I'd put on it.

As for powders, if velocity and shooting those bullets extremely fast is what you are after RL17 is likely going to be you best bet on powder. RL16 will work well too and be more temp stable but it won't produce quite the same velocity RL17 will.

It sounds like you're already aware but these things are pretty overbore so barrel life isn't going to be very long. I'm hoping for around 600 rnds before the throat in mine is toast. I don't think anyone ever really builds a 20-250 with barrel life in mind though.

FWIW, if you just have a desire to build a 20-250 by all means go for it. I think they're a bit of a specialized gun and keep in mind you can shoot a 40gr Vmax from a 22-250 faster than you can a 40gr from a 20-250. I know the BC of the 20 cal 40Vmax is slightly better but with the extra speed of the 22 cal 40Vmax the ballistics even out not to mention a 22-250 is more versatile. Just food for thought.

As for triggers, if you are used to a Jewell, well, IMO nothing quite feels as good but they are more delicate than others. TriggerTech triggers makes a really nice trigger and is a bit more robust and not quite as sensitive to being dirty.

You guys are awesome! I appreciate all the replies and the help, it sure means a lot. Especially on my barrel twist, I was way off.

DAA, I talked to my ole man and Jason Thee and they told me about the write up, Iíve read it over about 3x already today. I learned a lot and I mean fast. Seems like we had about the same goals.

My uncle shoots a 20BR and itís a screamer, and is a serious shooter, bug holes like Iíve never seen. Heís trying to talk me into going that route instead.. BUT.. As far as I can tell, itíll have to be built as a single shot rifle, because it wonít feed. And thatís not something I want in a calling rifle.

Iíve looked at the 20VT, 20 Practical, BR, all of them. I donít really know why Iím so set on this 20-250 but I just canít help it. I shot a 22-243 for awhile and it was a real animal, and wished I never sold it. But I have been just obsessed with the 20-250 for a long while.

Iím well aware of the short barrel life, I donít at all expect it to live long. But if it lives even 400 rounds, say 100 for shooting, that leaves 300 dead coyotes if I shoot 100% in a perfect world LOL Thatís plenty for me.

I also totally get the 40gr 22-250 vs the 40gr 20-250. I absolutely understand that for sure. I just donít really have any need for the .22 since Iíve got my swift built. Probably still doesnít make sense since Iíve got my 204AI too.. lol but itís just what I want. Im still pondering about it, but I think Im gonna do it.

Unless yíall say thereís a better route to go out of this donor rifle. Iím pretty set on the 20-250, no doubt. But if thereís another screamer .20 out there that Iím missing, Iím all ears.
