Custom .22-250?

FireFlyFishing said:

I love the .22-250 cartridge. The SAMMI spec is lame compared to modern standards and projectiles though. So…contemplating a .22-250 custom with a 6" or 7" twist barrel. Now we're talking old cartridge with some legs.

Before you start throwing 22 CM or others at me because this or that…I have lots of .22-250 brass laying around…like a lot. I also have a metric crap ton of 77 grn SMKs laying around.

What action size would be adequate? Should I throat the barrel for the specific bullet I will be using?

Intended purpose: Coyote gun. That's it….just a yote gun. I'd run it suppressed. Long barrel ok…even with a suppressor.

How would you build this rifle?

Boy oh boy, you guys and your hi-bred cartridges. That ain't me, but I did have Rem 700 action sent to Shilen Rifles to get it rebarreled from .243 AI to .22-250 Rem with an Alternut bull barrel. for a grand total of about $675.00 in June of 2022.
The folks there were a joy to deal with at that time.
The action already had a Jewel trigger so that was good.
I guess I'm not understanding the desire to go to .22-250 AI for just a 150 fps increase in velocity.
OK, no trimming the cases, but I set up one of my case trimmers for each cartridge I reload.
Yes, I suppose that longer and heavier, more efficient bullets for greater distance is driving this also.
The .22-250 Rem is such a flat shooter that in my world, lower Michigan, I won't need any better cartridge.

Just. AI the .22 Creedmoor, I did.

Left to right.

22x47 Lapua 77gr MK
22-250 case
22 Creedmoor Improved (40 Degree) 80.5gr Berger full bore

Had the 22 Creedmoor AI done years ago. I called it the .224 Bleedmore. I see recently a few on YouTube have copied it. Whidden did my dies.


Hint. I don't own a 22-250.

Well, after reading all the posts here…if I were to get a custom twist barrel, why not get the AI upgrade at the same time. I can use the same brass…so….

I know for a fact the a 80.5gr Berger full bore bullet. Launched from a 22 Creedmoor improved @ 3400 fps will flat crush a mule deer and turn both lungs to soup at just shy of 300 yards. Bang! Flop!
