New Brass & Load work up

[maxxsmart]

I have been reloading for a while now, but the only brass that I have used ( New Winchester 308) is reaching end of life. The general rule is to work up whenever replacing a component in your recipe... So my question is, if I go with a new lot number of Winchester 308 brass, would the general recommendation be to work up the loads again? I know going with a different brand of brass would require a new work up, but does this also apply to simply purchasing new brass of the same brand that the original recipe was formulated from?

Thanks in advance for the help.

i say buy the brass and prep a dozen or so with your same recipe for that brass. If your happy with the results it'll save you the whole work up load routine.

Load them and go shooting.
Same thing if Rem or Federal brass.
Nosler brass will give somewhat lower speeds(and pressures).
Hornady brass will give somewhat higher speeds and pressures.
I also have some Speer brass(made by Rem) that acts like win/rem brass.
I have loaded max loads in all the above and not had any problems.

No need to overthink it especially if not loading max loads like I do for hunting.

I found some Winchester 308 brass that weighs 180+ grains without the primer, looks just like the 158gr brass. I dunno if they retooled or what but I would weigh the new cases.

Cant tell you what I do,it is far to scary for most.

Thanks... My OCD with attention to detail is over the top sometimes, so I try to keep things as consistent as possible. Never had any signs of max pressures, so I thought it would be OK.

Weighing was exactly what I was going to do with the new brass I didn't get any answers here, which makes me glad I wrote down the sample weights I took from the first batch before processing when new.

Thanks for the responses.

"Highpower"... Now I am intrigued by your methods.

It would probably dependon how hot are your loads.

Since I don't do max loads - mostly a little under 1/2 way between min / max - I don't really worry about cases . [ lots of range brass gets mixed in ]
End of life means split cases , primers falling out or bad dings .

Supposedly as you reload the brass you are stretching the brass with each reload and trimming off the excess. Over time it will make the material thinner and create bigger case volume. I don't think it is enough to make any noticeable difference but some sharp shooters do, hence they mark how many times the brass had been reloaded.

To get you back on you should had chronographed the speed of your pet load and whenever you change any component you want to get roughly back to that speed if possible.
