223 Lake City Brass

Does anybody know if this brass has crimped primers? Ran across a good deal on 500 rounds of brass.
I'm not set up to use crimped primers. Any suggestions?
 
Yes, LC brass has crimped primers. You could send it to me /ubbthreads/images/graemlins/grin.gif, or you could get a primer pocket swager.....Dillon or RCBS. Sinclair's primer pocket uniformer will also do the job quite well. Chuck it up in an electric drill and it won't take long to do a bunch!
I would recommend that you do not use a primer pocket reamer, like the Lyman. Results are inconsistant at best with that type of tool.
Good luck!

Some lake city brass has crimped primers, some do not. LC match brass does not. This is some of the best brass for the .223 or for that matter, the .308. It is worth the trouble to chamfer the primer pockets.

About 1 turn or so with your deburring tool will remove the crimp.



Buying a bunch of stuff to remove the crimp is silly.

... what Nasty said. Get your deburring tool and remove the crimps while watching TV.

My buddy shoots a .223, and our dads work at the prison so we get free brass for it. Some of it has a nasty crimp, we just debur and then use a flashole uniformer as we go along.
 
LC brass, is superb. It'll give you more internal capacity than anything else out there in .223 Rem. Standard .223 cases give you 30.6-ish grains of internal wet-capacity, R-P is 30.5, all the way down to mil-spec stuff, which is 28.5/6ish. My LC once fired in .223AI is 33.3 grains, and that's plenty to send moly'd 55 gr. V-maxes WAY past what a .223 ought to do.
 
Well I went through and sorted the brass and had around 20% showing some slight marks on the case. Looks like some kind of speed loader perhaps that left slight indentations on the case. Is this usable brass?

I bought the dillon crimp remover and 1500 rounds of LC brass. When I got the brass, it was LC 07 and did not have a crimp. Didnt even get to use my new toy.

In 223 military brass is normally not thicker than civilian brass. Also, LC is military brass.

Anybody try the RCBS Trim Mate for decrimping the primers?



Yep, that is probaly the best $90 you will spend on a piece of reloading equipment. /ubbthreads/images/graemlins/wink.gif

I think the extra capacity is coming from the AI not the LC!

peace.

Jack;

Having measured the internal capacity on LC brass, R-P brass, W-W brass, Federal brass, PMC brass, Hornady brass, and IMG brass, I can tell you, first-hand, that LC has the most internal capacity. 30.6 grains of water capacity, is the high-end average for LC. R-P is close at 30.45 grains, high end average. After that, it falls off fast..... Federal and PMC (garbage, imho) at about 30.25; Hornady and W-W at about 30 even.... IMG can go anywhere from 30.3 to 29.8.... and varies from lot to lot like nothing else.

The FNM and general mil-stamped stuff comes in at 28.5ish, on average.

That Lake City might be considered mil-spec brass, and in fact is at times, is fine..... but it don't act like it nor measure like it.

Knowing that the LC brass gives you, on average 1.5 gr. more internal capacity than SAAMI specs, can lend considerably to working up loads to and just above book max. Using it for .223AI brass gives you considerably more than what the .223 and .223AI are supposed to be able to do.

For instance, a SAAMI spec .223 load, based upon 28.8 gr. internal capacity brass and H335 with a 55 gr. V-max, tops out at about 26 gr. and 3350 fps. Using LC brass and it's greater capacity, you can easily bump to about 27.5 gr., and nearly 3500 fps.

Going AI and moly, I get 33.3 gr. internal capacity via the LC brass (vs 30.8-31.0 gr. via Federal or Hornady), 30 gr. of H335, and 3600+

Greater cubes inside, can make a good bit of difference, and LC gives all that can be got from the .223 hull (R-P is RIGHT there as well).

On the AI, it is.

That the standard LC brass gives 30.6 grains of internal capacity, vs the others which give less, has nothing to do with AI, as they haven't been formed yet.

There is no SAAMI spec for internal capacity.

There are no SAAMI spec loads based on internal capacity.

SAAMI only defines the physical OUTSIDE dimensions, and peak pressures.

They do NOT define internal volumes or powder weights or loads.
