22BR brass question

[kd4avp]

Hopefully I am in the right forum for this question.
Looking to build a 22BR.
Is any one doing this caliber in a no turn neck barrel?
If so, what bore did you end up with?
Not sure if I want to add another rifle to turn necks in order to shoot.

Thanks!

I had one built. I did it with a .254 neck. I think you go to .252 and still be no turn.
I made it a little bigger because it was used for prairie dogs and guns get a lot of crap in them out there.

0.250-.251 loaded diameter for Lapua with my lots.
0.249-0.250 loaded diameter on Peterson with my lots.

I’ve been using a 0.253 neck because thats what Jim Borden has.

Neck YOUR 6BR case down to 22. Stuff a bullet into the neck. Measure the neck. That's what you will be dealing with.
Go maybe .002 or .003 over that and be sure what brass YOU end up using comes out the same. What works for someone else doesn't mean it WILL work for you.

I still skim turned mine to knock off the high spots.

FYI there are Lapua and Remington reamers out there so be aware of that.

I had one at .258 neck diameter with no issues. It was larger than I would have spec’d, but worked well.

My no-turn 22BR chamber is a .255 neck. With Lapua cases, the necks measure .2530 across the pressure ring of a flat based bullet. With those dimensions, a bullet is a nice slip fit in a fired neck.

Good shootin' -Al

Yes 254 and 255 are most common.

With the later Lapua cases, you need to be pretty careful with a .254 neck. The early 'gold box' Lapua worked with a .253 neck and a .254 was a bit of insurance. Many of the 'no turn' 22BR reamers are spec'd on the early Lapua cases and haven't had the neck diameters changed to reflect changes.

In a .253 or .254 neck 22BR chamber, the Peterson and Norma 6BR cases are the safer play. Even in a .255 neck 22BR chamber, they will provide an extra bit of insurance with no accuracy loss.

Blue box is thinner than gold box from my experience. Not the other way around. About a thou smaller bushing for blue box than gold box.

Blue box Lapua 6BR, necked to .22 in a Redding 22BR Body Die, then f.l. sized in a Wilson 22BR bushing die. Bullet is a BIB 52 gr. flat base with a .2241 pressure ring. This lot is what I made the cases from for my .255 neck 22BR.

My other 22BR using 'gold box' Lapua cases (made the same way) results in the necks at .2515-.2518.

The main take away is to make sure there's adequate neck clearance. With 'no turn' stuff, it does leave the shooter at the mercy of the brass mfg. For example, there's one box of Lapua blue box 6BR here that has pretty significant neck thickness variations...close to .002 on 1/3 of them. For the no turn barrel for one of my 6BR's, brass gets checked and the culls go into a box that get neck turned for the 30BR's.

It's always better to check and know than to assume and hope.

Definitely weird. I've not had that but I don't doubt it could be out there.

My 22BR reamer has a 0.255 neck and 0.130 freebore to shoot the 85-90gr bullets. I'm on my 4th barrel, Straight tack driver.

I stepped my Lapua blue box 6BR brass down in 2 steps. 258 bushing then a 249 bushing. I didnt loose a single piece of brass and Ive done 500 or so now..

I use a 252 and 249.

252 is for 6xc to 22xc.
