Welp picked up some of this magical powder eveyone keeps talking about and a box of these 52 gr BTHP's. Think they will be the best thing I could ask for given all the constraints a 1:14 twist gives a guy

Next to one of the 55gr SP's... Which onna side note , I was reading and apparently the cannulated 55gr HP's work better , terminally wise ..... Folks think it's because the cannular works kinda like this deal on a nosler partition....KINDA ...... Sorta kinda ..... In a very liberal sense lol




Will say though it has a bit of a large hollow point compared to something like my 69 gr RMR BTHP's

You want to see a large hollow point on a 52gr 22 cal bullet, look at the Speer. I used them for years on local varmints and Kansas prairie dogs

and those folks have no idea what they are talking about. Big difference between using a crimp/cannelure to hold a core in and an actual partition style that can not come apart, no matter how hard you push it.

Not that you need a partition style bullet for small critters.

Alright alright alright new bullet time.
So first I gave it a cleaning , I have cleaned it since I fist got it so it's got 70 odd rounds with of carbon and copper built up
Threw it in the vice and acquired a good bit of hoppes down the barrel and just let it eat over night while I was doing other stuff
Then did my usual cleaning deal , hopes dry patches , scub with JB bore paste yadda yadda y'all know the deal


And a looky loo on the inside



Found this deal....looks like something you'd draw to summon a demon or something lol but at least the lands cleaned up nicely



And new bullet means new seating depth so made a lil split case




So , how this works , the cut allows you to ad or release some tension on the bullet , ya want enough to hold the bullet and let it slide back with a decent bit of effort...but no so much that it will allow the bullet to stick it too lil it just plop out. Anyhow stick it in long ,measure it.


Fit it in the bolt rim under the extractor and chamber it



Gently pull it out and take that measurement. Do that a few times get an average an That's where your hitting the rifling .do with that what you may ...some people jam it down people jump alot...me I like like .003 off .

Now.... something I thought about was that when the gun actually runs...the rim of the round does go under the ejector till it's in the chamber and the bolt is slapping the back of the case .... As shown


some mabye ... Something might be different maybe I should try it ... So too that dummy plopped it in the chamber dropped the bolt release like I would if I was reloading a mag and


Yeaaahhh that's a bit different so.... I basically have two different deals now j can work off of and since the second is more like how stuff actually works...guess I do that ! So ended up running like 2.045, yeah that's supposed to be jam....but it ejected fine and easy with no marks ...so ... It can't be jammed idk..

So as far as powder I WAS going to use some of the magical H380 buuuut apparently that's only for like 55gr and up so we'll have to wait , BUT again I have the options between accurate 2460 and 2520 and since 2520 gave such good results last time just gonna run with that

And gonna go up a bit because as y'all saw this 20" barrel is loosing like 300fps vs book



And not alot of case fill

Ok and the set up same as last bipod read bag magneto yadda yadda


Feeding from the mag and was recommended to do a lil test to see if I get any bullet movement due to recoil. So measured the first round in the mag



Bore sighted and re checked on paper at 50yd and it was all over the place .... Ends I only tightened one screw on the mount .... I'm not that bright I've told y'all this lol

O and the bullet test !...yeah nothing changed lol same measurement

Fixed that and took another round at 100yd to get on paper but .....yeah imma be 100% I don't have any issues at all fed perfectly is just a DREAM to shoot can watch my round impact with next to no muzzle rize and here be the groups



Sooooooo yeah ... That's what .. 5 outta 6 under 1MOA ? Velocities are on the lowered side for a 250 but again ...20" barrel feel like I could stomp on it a lil harder and play with it some.more but this is bolt gun data and this is a gas gun so..... Not the safest thing to do....soooo guess the question is now ...which load ?

So its not safe to load them to 22 250 speeds?

..I mean you CAN the issue is this data is for a bolt gun, bolt guns can usually handle way more pressure then a gas gun before stuff starts breaking. That and I have a 20" barrel which is already hampering me pretty bad . That being said there's so tech savvy off the book speed demon guys I follow who routinely cook up loads for shorter barrels and gas guns that can keep up with the "normal " ones and stay within safe pressures....but that abit outside my deal

My bolt gun has a 22 inch barrel I think. Not in the mood to dig it out. I get 3600 without using a max book load and 55 grain pills. You lose a little cause of barrel length and the gas system but I would think 34-5 is very doable. Can't you just ease toward max loads looking for pressure signs on the brass? If you have not guessed yet there is a lot I dont know about ars.

PS I just bought my grandson a new 270. Like you I am married. Think I would get that woman look if I dont wait till spring to buy another gun.

my 14 twist 22-250 shoots 55 gr fine, even the 60 gr nosler partition, the nosler 64 gr bonded, and thee 64 gr. winchester power points. its not bullet weight but length, those bullets are the same length as a 55 gr.

These shoot good for me- I have 1 in 14'' barrel

The bottom 2 shoot the same hole for me. I load them all the same with 38 grains of H 380. Don't shoot things closer than about 70 yards with that 40 grain bullet. You might get something on your shirt...

I wouldn't change a thing with the groups you are getting.

I could but again gotta be careful with em these AR bolts. For me it's just extra wear and tear annnnd doesn't help this is one of the cheapest companies so no super trusting of them lol ... I might ask about some different lowered pressure powders and see but I'm pretty happy as is

You know I forgot Barnes made bullets lol. Dont think I've ever messed with them. But anyhow like I said before I'm in an odd place because well I don't really do o have the ability to do what most do with a .22-250 blowing up prairie dogs or sniping gophers and the like . So alot of the bullets folks like for .22-250 arnt the best for me just to explosive. ...

Honestly I didn't n't expect this thing to work figured it would be something I pulled out to fiddle with Evey so often when I was bored .... Now I got a 15lbs gun that shoots good groups...but only with things bullets

I meant to order some but dint see any in stock

Did you chrony this stuff? I see it did not damage the rifle.
