Differences in 22BR brass manufacturers

[Roadrunner]

I have embarked upon a 22BR build and suddenly discovered that there is a possibility that Lapua or Norma brass may be slightly larger than the Remington original spec. I have received the dimensions from Shilen and learned that their reamer appears to be the smaller of the options out there, i.e. - original Remington dimensions. In what I have read to this point, making 22BR cases sounded like a slam dunk until this possibility of slightly difference sized cases/chambers, depending upon manufacturer arose in my mind. I have had the barrel pulled temporary until I can learn more about what I am doing. (Apparently, many have gravitated to the Norma spec.!?)

The real question is if I have the tighter chamber, will I still be able to make the cases from Norma 6BR brass?

Any help here would be appreciated.

look over these , some are of interest to your project others are not http://forum.accurateshooter.com/search/34926758/?q=22+br&o=relevance&c[node]=8
In the reading you should learn what most consider a NO TURN neck chamber ID using 6 BR lapua brass to form your 22 BR brass
Another point to consider is the throating / freebore, OR, where you want the full OD of the bullet you plan to use in relationship to the neck / body junction of a case. I had mine set up so that it didn't matter what bullet I used [75 A Max the 80 gn SMK's] the full Dia. of any bullet was above the neck /body junction

Next, I don't think Rem. has made their 7 BR brass in a long time. IF who ever you choose to chamber your barrel is still using a reamer based on the un available Rem 7 BR cases, I'd look else where.

I had a reamer made last year for 22BR, and the print shows minimum chamber length of 1.575. If what Shilen gives is shorter, I would request either an updated reamer or as above, go elsewhere. I don't think it's advisable to chamber it for long gone unobtanium brass and legacy specifications for that cartridge.

Thanks for the reponse!

I am new to this forum and am having difficulty getting a reply to post, but I do appreciate the responses.

Baddog0302 & Hogpatrol!

Thanks to both for the insights. I'm finally figuring out how to reply on this forum.

Hogpatrol, I may be too far down the road to turn back, however I do have things on hold for a bit. Regards, RR

Baddog0302: Forum link you gave has been helpful. Thanks much! RR

Baddog0302 & Hogpatrol: I am at this point 13 years into retirement and would definately like to be shooting this summer and not delayed until next summer, so that is why I may seem somewhat unwilling to follow excellent advise which may seem to test your patience.

As I said the project is on hold; however for the sake of discussion, let's assume that I already had the barrel with the "small" chamber. Is it likely that with FL resizing, neck turning (I had spec'd a tight neck), and trimming I'd be able to use the cases that are currently available in this chamber?

I know this isn't ideal, but it seems that someone out there must have already faced this issue. I am searching for some hint that it is possible to do this as originally planned. I know it is not the ideal situation and it would look different to me if I were 10 years younger. I sort of thinking that if it proceeded as planned and could get it shooting this summer, well, great! If not, I could then get the chamber "fixed" over the winter (no shooting in the winter here, my doors freeze shut!) and be ready next summer. If I wait to get the ideal chamber reamer now, I'll not get any shooting in until next summer. At least I'd be doing something with it this summer. A little stupid, maybe, but is that totally crazy? Comments??

Do you have a reputable gunsmith in your area? He may have a 22BR reamer that would fix your issue.

Some years ago, a friend had a chamber that had been reamed with a Remington spec 6BR reamer. For Lapua brass it proved to be unsatisfactory, and that could not be remedied by sizing. The solution was to have the chamber opened up with a suitably dimensioned reamer. IMO your I don't want to take then time to do this right approach will be doomed to frustration and failure. Why do you ask for advice and then ignore it?

BoydAllen: Thanks for replying and I tried to explain why I am being so pigheaded! (It's an age and expiration date issue!) Your experience, though second-hand, is what I need to hear. At this point it is still hypothetical. I am reasonably sure I would have to buy a reamer and that would push everything back. I'm still evaluating what the success probability is of making the silk purse from a sow's ear which seems to be direction I got headed.

Your observations are appreciated!

RR

Hogpatrol: It is the limited gunsmithing in the area that had me on this approach; however, limited is not the same as none. I'm reasonable sure that if I go with local talent, I'll be buying a reamer. That is another unknown for me that I could easily screw up as much as I have the "simple" barrel order process.

I think you have a reamer. Could you share the specs on that?

I don't even know if it's a one reamer process or two. Roughing & finishing??

I bought a 22BR barrel a couple of years ago from a fellow who assumed it was chambered Rem (1.520). I always check chamber length when buying a barrel and it turned out to be a Norma with actual length of 1.580. Either his gunsmith didn't tell him, or he didn't understand. So he trimmed an entire box of Lapua brass unnecessarily.
Any good smith should include a chamber print, but it's always good to measure with a few very inexpensive tools from Brownell's.

Sorry, PMs? ?

Sorry, PMs? ?

I believe that the reamer called for is 22BR Norma. A 22 BR remington is a shorter trim length.

 

[Baddog0302]

I think a few more details might help in offering help.
1. Is the chambered Bbl. you started your process intended for use as a DIY install on a Savage
or a Rem. as a RemAge ??
2. Had you planned on Shilen doing everything , chamber, as well as install and head space the bbl. ??

 

[hogpatrol]

I saw the print. It's the REMINGTON 22BR, short case. I'd get the reamer for the available Lapua and Norma brass and re-do it.

Brownells has a device made by Sinclair called a chamber length gage insert. You will have to sacrifice 1 piece of brass to set it up to measure your chamber. Caliber specific .
