Is such a variance in weight common?

[Newbie]

I was sorting out brass made by Lapua, I recently purchased. And began to notice that the weight spectrum is much broader than what I have experienced with the Federal GM, I chose Lapua since many recommended Lapua for the 6.5-284.

I have sorted 100 out of the 300 I purchased by the grain, I have yet to sort by the tenth of a grain. And with in the 100 cases I see a weight range of 6-7grains.

With in that range I had:

2@192gr
19@193
8@194
5@195
16@196
49@197
1@198

Is this variance normal for Lapua?

I have no experience with Lapua 6.5/284 brass, but have lots with other Lapua brass. That sounds like the worst lot of Lapua brass ever made, or you need a new scale.

That is the feeling I have been getting after hearing so many praises for their products.

Many times I questioned the results of my digital so I cross checked it with a Redding Beam scale and also a Hornady Beam scale.

And the results would be with in one to two tenths of a grain.

Cause I spent most of the day yesterday going through the last 1000 of the Fed GM brass for my 308, and the scale would read 176-177 consistently. With only one or two that were in the upper 160's

How well does Lapua stand behind their products?

I think I would contact the vendor you bought them from and ask to return them. With .223 I've never had more than about 2gr total variance with the bulk landing somewhere within a one grain range and the bulk of those landing within maybe .3 or .4gr. Yours seems very bad indeed. -Rod-

The 6.5-284 is a much bigger, heaver case than a .223 Rem, so you would expect a larger extreme spread of weight. Still, what you got is not what we've come to expect from Lapua.

For a recent lot of the .223 Rem match brass:

Sample=100 cases

Aver weight: 93.35
Wt. ES: 1.2 gr
Wt. SD: 0.31 gr

If you were to double those numbers,getting you to the range of the 6.5-284's case weight), that would be a spread of 2.4 grains.

That is pretty bad!

Worst lot of Lap 6.5-284 I had was a 4gn spread over 200 cases and I thought that was bad...previous was 3gn spread.

Last lot of 200 223 cases was 0.8gn

I contacted the "vendor" I made the purchase from. And the response I got was since it has been 30 days since the purchase they won't honor a return.

But suggested that I get in touch with their distributors and see if something could be worked out.

Still waiting for an answer back from their supplier. Don't know if they are close for their fiscal year doing inventory or what the possibility is. But all I got was an voice message.

Though in your opinion, is there "really" any way possible that this brass is salvageable?

Cause I partially checked the other two boxes and would get the same results. Some at 192, some at 197, and so on. :,

Was this from a sealed box?

They were sealed til I opened two of them to sort them by weight.

lot #? Should be top of box, left center if this is a newer lot.

I to recieved a not to great ES of brass for the 6.5x284.

Last spring I put a new barrel on the gun & wanted new brass only to find out the whole country was out of Lapua! I waited till September to finally get my hands on the last batch to ship over the big pond.

Im going to go out to the shed & see what my Lot number is.

It wasnt that bad if I recolect right.

I used to run the Honady Brass & found out after the first season something was not right & started to weigh cases as part of my reloading proccess. Boy was I in shock. at that time no one made brass ready to reload for the 284 except Hornady then shortly after I purchased Norma & Lapua got on deck.

Here is what I did:

Istead of throwing it out, I took each case & sorted it by grains. then down to the tenth. put it in a reloading block & loaded it from lightest to heaviest., thow out the couple that are way out of the bell curve). So when I went to a match there was no more than 1/10th of a grain diff between the last two cases for weight. Ive shot clean @ 600 & 1000 yards that way with a scope on the gun. Now get this. I applied the same tecnique this last summer,as always) & shot a 200-11X in the wimboldin at Perry.,Managed first Master) I was on the same relay as Mid Tomkins so I did not go to the shoot off :,

Then in the fall using the same tecnique with Lapua Brass shot a 980/1000 at the regional. It seems to be working out real well.

If you cant return this stuff, witch I would try to do, this may be the alternate course of action.

Hope this Helps

Yes the information you provided is a plus. I have learned that you never say no to any one's advice, it might become useful someday.

In regards to returning it, I spoke with the retailer and they have a 30day policy and and and...........................

as I was typing this reply I got a phone call from Nammo Inc wanting me to return the brass to them and they would send me 400 pieces in exchange of the 300 I purchased.:thumb:

That is great news.

My batch was not near that bad. I just looked over mine & it weighed from 195.5 to 197.7 And only 3 on the lighter or heavier than that, That I tossed.

Again good luck.

That is very similar to the results I have got with the Federal GM brass for my .308 Win. Nearly all of it was in the 176's and 177's. But there was a few lights in the 175's and a few heavies in the 178's. And two lighter than 175, one at 174 and one at 169.

I figured the 175's would work perfect for plinking in my M1A. Work up a charge that won't create such high pressure, yet still capable of cycling the action. And pitch the rest.
