Lapua Brass - soft?

[med358-boise]

I put 60 rds of Berger 245 EOL through one of my 300 PRC this year to use the brass for reloading and to gather initial data. Every piece had ejector marks, swipe and was fully formed to the chamber on the first firing. Not even crappy hotnady brass had that issue.

I also fire formed 300 lapua 6.5x55 swede 139 scenar factory ammo in my 6.5 Addiction stainless barrel. I followed the same procedure as the carbon barrel. More than half of the rounds were bulged above the web, they had ejector slot marks on maybe 1/4 of the cases, some of those were bulged and others not.

I've been so thoroughly unimpressed with the last 260 rem brass, 6.5x55 swede and 300 PRC brass that I have gone away from Lapua altogether. The inconsistency in their virgin brass case lengths, the headspace of virgin brass, the fact that some primer pockets uniform with very little clean out. Some don't even touch and others take repeated cuts because of how much gets munched out.....I don't have anybof those issues with the over 8k pieces of Alpha or the 300 pieces of ADG I've gone through.

I just bought a bunch of peterson 300 PRC to replace the virign Lapua I was going to use. I have never used peterson before, so time will tell if it's as disappointing as Lapua has been.

So, a Ling winded complaint to sat, yes...I have noticed lapua cases are soft lately...too soft, especially at the web on that one lot.

thanks

With Lapua brass in those rifles eliminate starting too low for so-called safety check. It is two combined factors in his normal routine process that may be causing a problem. I've never had a problem with Lapua and I don't load caps in a real rifle.

What are the factors that may be causing the problem I have described that arise from a load of 41.0 grains when the listed load range is say 42.0-46.0?

What criteria do you use for determining safety check rounds are unnecessary for a cartridge?

What criteria do use for defining a "cap"? for example if the listed starting load is 42.0 is loading around at 41.0 considered a cap?

So, now you are getting more specific than your original post. That's fine. Your shopping for answers that your Lapua brass is not good. Your Lapua brass is not good. Let's go with that.

Actually, my last post is driven by the content of your replies and I am not shopping for answers that Lapua brass is "not good". Everything, I have previously read (except for 1 post above) is that Lapua brass is fantastic and have no reason to dispute that despite the experience with these cartridges and I am trying to determine if it is an anomaly or am I missing something. That is the reason for my inquiry.

You have made three statements:

1) Try not using pop gun safety loads with Lapua brass in those particular rifles.

2) With Lapua brass in those rifles eliminate starting too low for so-called safety check.

3) It is two combined factors in his normal routine process that may be causing a problem.

Those statements are not very well defined and lack specificity. Additionally, they appear to be counter intuitive since what I am experiencing is similar to signs of a pressure problem and your statements seem to be implying that I should eliminate a pressure check step and there is information above that states Lapua says reduce published max by 10% because of the nature their brass.

So I am asking for clarification of what you mean?

You don't need specifity with your experience. I'm not being counter intuitive. You just keep doing the same things over and over again like trying to start a lawnmower out of gas. If my last post prompted you to add more specifics to your problem than you were leaving out pertinant information in the first place. Chances are those specific rifles don't like the Lapua brass your using. I regret getting involved in these conversations. Before the Internet I don't recall reloaders having so many **** petty problems.

Got it.
We went from your replies of:
Post 17 - On those two knock off that boutique reloading style. It's wrong from the start.
to Post 19 - "Try not using pop gun safety loads with Lapua brass in those particular rifles."
to Post 23 - "Only with Lapua brass (308 - two different rifles, 7mm-08 1 rifle, 6.5x55 1 rifle)..."
to Post 27 - "With Lapua brass in those rifles eliminate starting too low for so-called safety check. It is two combined factors in his normal routine process that may be causing a problem. I've never had a problem with Lapua and I don't load caps in a real rifle."
to Post 31 - "So, now you are getting more specific than your original post. That's fine. Your shopping for answers that your Lapua brass is not good. Your Lapua brass is not good. Let's go with that."

In between each of your replies, I asked the same basic question - can you be more specific/can you explain why you are making the statement?

Which brings us to your last reply Post 34 - "Chances are those specific rifles don't like the Lapua brass your using." (I left out the non-specific, unsupported, and incorrect assertions)

I appreciate your final assessment of the issue in Post 34 because it solidifies how I should interpret your previous Posts.

Best of luck in 2025

Not sure if you received needed answers, but I'm glad you brought a potential issue to light.
Thank you
