Not My Idea of Fun!

It's amazing the variances in case length in new rem brass. So I figured I'd trim them back from the start.

Now apart from chamfer and deburr should I do any other case prep?

How serious do you want to get?

When all same length weigh and cull
Uniform primer pockets
anneal necks
debur flash holes
run them through your die and check uniformity of sized brass from your dies
plenty more you can do just depends how excited you want to get, alternatively you could just buy better brass and skip half the crap

:lol: :lol: :lol: Looks like you and I have been doing the same thing today, I just spent around an hour running the 300 win brass I got the other week through the FL die, then trim to length, chamfer and deburr, uniformed the pockets, then stuck them back in the cupboard till I get motivated again to do some priming. That is my normal prep for any new brass I get.

hahaha I sized them last night, but yeah mate looks like you and I are just as keen. I'll have to get a primer pocket uniformer, I think I'll do that and deburr the flash holes and leave it at that.

I reload but I never have really worried about caseprep short of size and chamfer, but I figured since I cant shoot it may as well get my brass all prepped.

Keith, I'm that keen at the moment I have been thinking of buying a Zastava Stainless in 300winmag so I can start playing with it, then getting the other bits put together when they finally arrive. I can always sell the other one after the build is finished. :shock: :lol:

Hey Keith if you go to a few comps, the br shooters wi;; tell you they all change dimension slightly after fireforming in your chamber. They told me fire them once, then trim. If you measure them all again after firing you might be sad

Remington brass? The flash holes are punched to match a Remington bolt. All offset from center.

For basic case prep that gives the most bang for buck
FL size to uniform cases
Uniform primer pockets
Trim to same length

You can debur the flash hole but you wont gain that much from the exercise.

Next best thing is to use a bushing die and limit the amount of cold brass movement while gaining some control over neck tension.
Keep your brass clean and as Trev mentioned re-check after first firing

Or use a lee collet 8) hmm maybe I need a flame suit :lol:

My old swede put 3 into 0.55 outside to outside yesterday, remmo brass, collet sized necks, lee hand trimmer 8) Love the old girl.

I think it depends on what your shooting, trim to same length load em up and see how they shoot.

I was watching reviews on the hornady case prep centre last night, trim to length, debure, chamfer, clean primer pockets all nice and quickly and easily. Pity they are like $300 or more

if you think about, if they expand a pooptenth to fireform to your chamber the brass has to come from somewhere, if they expand then they shorten. Maybe too little to notice, but I like the logic and trim after firing now.

Glad I am remembering this stuff, havent had new brass for years and my 257wby brass turned up today. Insane looking case :twisted:

See Trev I told you all that crap would come in handy one day lol ...
I think I have some old brass either 7 or 257 wby lying about its been resized to 6mm but you should be able to expand out to 257 again. I will send it with that scope. You might want to anneal it I was running it hot in a wildcat 6-257wby .... loads were around 73 -74 grains of AR2214 (replaced by 2213SC) with 105 bergers they were pretty quick around 3850fps or better as I recall. Anyway I will throw them in.

So are you guys saying that I have screwed my brass?

I figure worst case I'll FL size them again which should stretch them more?
