I picked a 20” rifle length medium weight barrel since the added length of my suppressor will be in it.I like the . 22-250 cartridge. Tell me about your build; I’m intrigued.
what barrel length did you get, and what length gas system? Did you go with an adjustable gas block?
It is the BCA. But I didn’t want their side charger so I would be stuck with their bcg. The upper receiver fit great on my aero precision lower. My first bolt gun was also a 22-250 Winchester model 70, and I still have it. I really like that caliber too.First rifle I ever purchased was an M77 in .22-250. Great shooter. Always loved that caliber. Killed a number of whitetail with it...along with a number of yotes back in the day.
I recently purchased a .243 upper from Bear Creek Arsenal. They also have a .22-250 and 6.5C upper. Thought that might be where you got yours!
If you get the gas port sized right and the matching buffer weight and spring it should cycle properly. BCA also uses a gas tube that is too short. I got a Wilson Combat gas tube that reaches the middle of the cam cutout in the receiver. I drilled the gas port bigger too. And put adjustable gas block on it. With a 5.3 oz buffer and orange spring. AR10s can be a bit picky until you get everything right.The .243 I got from them has not yet made it to my Anderson Manufacturing AR-10 lower. From Youtube, it appears they fit together fine, but will run into the occasional FTF. Mine was bought as a cheap method to add a caliber, so rapid fire is not even on my list as far as deciding to purchase. Who rapid fires .243 and .22-250 anyway. I wanted it for a game procurement tool, and that should only take one shot!
There have been a couple, Olympic made one years ago that worked but they are out of business. Bear Creek has them either complete rifles or just uppers. The reason they don’t catch on is because of the taper of the 22-250 cartridges. That makes feeding from the magazine problematic..22-250 is such a smokin' caliber. I honestly didn't even know anyone made an AR upper chambered for it.
That was my next question, is there a caliber specific magazine for it... Do you use an AR-10 mag?The reason they don’t catch on is because of the taper of the 22-250 cartridges. That makes feeding from the magazine problematic.
Bear Creek recommends a Pmag 308 gen3 10 round. I have two of them and they work ok if I don’t load them full. I am still trying to find out what folks have been successful withThat was my next question, is there a caliber specific magazine for it... Do you use an AR-10 mag?
A few years ago a buddy of mine built a faster twist 204 Ruger with a 22" barrel. He was shooting custom bullets for it that were 45-50gr range. He could reach out and touch the Prairie dogs with that one even on windy days.I've contemplated building an AR10 in .22-250, also thought about building an AR15 in .204 ruger.
I do have some extra parts, maybe I'll get around to that this year.
This is where I break off... and you answered all my questions pretty well about why we don't see .22-250 AR's often. The .22-250 is one of my favorite calibers, but to me there's not nearly enough advantage to give up .223 reliability and capacity. MY AR's don't hiccup, stovepipe, double feed, FTE, FTF... and they work great with a full magazine, so I'll move along on this one.Bear Creek recommends a Pmag 308 gen3 10 round.
