Thread: New Brass - do you full length size it?

Do you debur the flash hole before weigh sorting?

They are pics from the internet, hand primer tool jammed and set off a primer, the proximity detonation of all the other primers in the tool opens up the flesh, not good.

Treat primers with respect

I have yet to see the need as they all look OK but I do buy good quality brass such as lapua competition. What I am looking for initially is an obviously bad case made during production so all I am looking to end up with initially is 'safe' and consistent brass to fire form. eg from the last 400 lapua 308w cases I found one that was stuffed all the rest were fine and weighed within a few points of a grain. I think for hunting anything more is probably a waste of money and time.

There certainly seems to be a lot of myth, utter crap, marketing hype and secret-ism behind loading for extreme/best accuracy. This then has to become something of an odyessy of self-discovery for me as I dont feel I can rely on much info out there on the Internet. So the above is how I do it now, in time I intend to try different myths for myself to see if they make a difference or not. Bear in mind all these tools add cost to your kit and frankly there are many vendors happy to sell you their latest gizmo that achieves little or nothing. I am sure there are some about such as maybe @ebf is I think somewhat more advanced down the rabbit hole than me on the worthwhile tricks and techniques. One of the reasons I am making an annealer is neck tension seems to be very important so I am investigating this first. I'll let you know as I go along.

I have had half grain burrs out of Lapua brass. That's why I asked. I was surprised to say the least.
I agree, everything else aside consistent neck tension will turn an accurate load into scary accurate.

I anneal every firing and have improved the results I get on paper and with my chrony to a point where I know if I do my bit I find shooting to 600 child's play on steel etc.

That's enough internet for me today. I'm also now put off corned beef for a while....

Yup, all normal prep before sorting. So flash hole debur, size, trim, neck turn etc.

Thanks for all this information it's really helpful. The first time you encounter these new situations it throws up so many possibilities you end up rethinking everything.

Anyways my 100 new Norma 6.5 x 55 cases are mainly between 2.158 and 2.161 with a fair few outliers as low as 2.156 and as high as 2.163. Trim-to in the manual is 2.155 although my Lee trimmer on an electric drill takes it down to 2.151. So... do you think with that much variation it's worth trimming them? I'm kind of thinking might as well do it.

Sorry guys - late to the party, but had to waste good range time on Sunday because I had to spend Saturday resizing new R-P 7mm Rem Mag brass. Bought it brand new a few weeks ago - didn't check it until I sat down on Saturday arvo to prime and powder drop my 50 new brass - only to find that at least a third had misshapen necks - not sure whether they were dented from prior handling or what, but wasn't too happy.

Moral of the story - should have checked it immediately I bought it!!

I'm a minimalist regarding working my brass.

I load for 223 using Norma cases and 308 with Lapua Palma cases.
The Norma brass has never been trimmed or full length sized and some of them have been loaded 7 times.
The Lapua brass has been used without trimming or full length sizing.

Each to his own, I prefer the minimal approach.
