I have some win brass and the top of the case is not straight. I have tried to cut it using the lee cutter but it can only cut so far. I have only fired it once. Should I just fire again or cut it manually so its all straight.

[ammosmith]

Yes.

Norma and Lapua is "top of the line" brass, never sen that kind of deformation on those. Just load and shoot

[ammosmith]

Yes...I do however put all of my brass including the Norma and Lapua through the full length sizing die to make sure they're uniform and trim to make sure they are exact.

I bought some new brass and was amazed how much of it was over length right out of the bag.

It's a good idea to check the brass, But i would stop buying from this supplier or call and tell them about it, Because i've never gotten new brass that didn't look or measure almost perfect, and i've been reloading for 27 yrs.

Thanks for the heads up. got some brand new LC brass and i thought I was good to go . Glade i saw your video first

alright so im not sure if this is the right place to ask but, i was seating my 30-30 bullets about the 7th or 8th one in what it looks like happened was that the shoulder got crushed, is that something i should worry about?

i bought new 30-30 brass and mine wasnt as bad as those. had to trim and make sure case mouth was round. also some new brass i bought the package was short a few.

On Norma brass,

I purchsed a single set of brass, 416 Rigby, out of which about 40 weighed 340 grains +/- 1 and 60 weighed 328 grains +/- 1. That was a huge difference. I have had to keep them separate and to treat them like brass from different manufacturers. So check everything. by the way, Nosler does some very fine 'custom' brass, that has been sorted and prepared. You pay for it, but sometimes this is worth it.

While I agree with most of what you said, if the new brass is the correct dimensions out of the bag, FL sizing will not further work the brass.

The best course of action is probably to check the brass in a case gauge, if you have one for that caliber. If it passes, simply address only the neck to assure it's round and has the proper tension. Also check that flash hole to make sure it's fully punched and no material "hanging" inside the case.

Okay, first, the brass is run through FL sizers at the factory. that is how the shoulders are formed to begin with. second, the deformation does not come from the machines that make it, but rather from other pieces of brass in the packaging. run an expander ball through the neck, trim, load and shoot. FL sizing just works the entire case more than is necessary, and will not "pop" out any dents or dings in the body, only make it the right diameter.

Besure to inspect your brass I have found cracked necks,cracks in the shoulders and deformed (not just out of round). All of the above stated conditions were found in new ( unfired) brass purchased from ' the log cabin' store. Maybe that is why there is always a few extra pieces of brass in the bag?
