The 22br experience

[Maidenfan539]

After watching @huntnful thread about the 22 creedmoor I wanted to start a thread about the 22 br. I am in the process of building a 22 br for coyotes and possibly whitetail in WI.

I have a Zermatt TL3 action.
Chassis will be a XLR element 4.0 magnesium
Triggertech diamond 2 stage
Nightforce NX8 2.5-20 F1 in Mils with Nightforce rings.
Brass is Lapua 6br.
Silencer Co Omega
My goal is to shoot berger 80 gr VLD's but plan to do some testing with the Sierra 69 HPBT.

Barrel will be a criterion shouldered prefit from Northland Shooters Supply at 24", standard palma contour with 1-7" twist and .100 freebore. Barrel specs say 4 pounds 9 ounces at 26", so I will weigh it when it arrives. I have shot a .243, 2 6br barrels and a 6bra barrel from them in PRS matches over the years and do not have anything negative to say about the barrels and customer service. I ordered the barrel the other day and there is a 12-22 week wait for the barrel. Plenty of time to resize the brass.

I have about 6 pounds of H4895 powder and plan on using CCI 450's. According to Hodgdon reloading for a 70 gr bullet and H4895, starting load is 23.0 grains. A few other google searches show people using up to 28.8 grains and getting about 3000 fps with 88 ELD-M's.

The brass neck thickness it right about .015-.016 and after reading a few articles, the recommendation is to turn it down to about .012-.013" for necking it down.

I will have plenty of time to research things further, but if anyone has any experience with the 22br, please feel free to post your results here.

watching, I have two 22 BR reamers in the drawer. Hoping one will work without having to turn necks. The 6mmbr.com forum has a decent amount of info if you are on there

I have considered building one many times, haven't got it done yet.
Accurate shooter has a little info on the 22BR here:

My necked down lapua brass is 0.250 loaded diameter, chamber is 0.255. Believe the freebore is 0.150 for 88 eldms. Also works for 77tmk. Bit long for 80 eldm and 85.5 Bergers, however those bullets all do fine jumping 50-80k too. I have two of these, prs trainer barrels. 90gr smk with 28gr varg going 2930 shoots half minute 10 shot groups on paper at 400y. Highly tempted to get a howa mini, open up the bolt face and run the Jefferson box mag with 2.43 internal length. This would allow me to use pretty much any bullet touching lands, as the longest bullet I have is the 88 and touching in 150fb chamber is around 2.380 coal. 77tmk touching is 2.235 coal. I might just go 22arc and skip the bolt face mod, but I'm already set up to load 22br. Would gain a slight boost in velocity and have lapua brass.
