Case trimming

[Mistered]

If ya don't already have one I highly recommend a Lee factory crimp die - especially with 30-30. If after checking length and if some are a bit short load them anyway. Unlike roll crimping the factory crimp die does not require exacting length to crimp.

+1 on the Lee FCD for rifle calibers. They are the way to go in my book. Just keep in mind the pistol caliber FCDs are a different animal. IOW they are not collet style crimp dies, they are either roll or taper crimp with a sizing ring. The rifle FCDs are collet style. You get consistent crimps without regard to case length. As long as it is in specs, you are good to go.

On straight walled cases I don't trim them very often. On tapered cases I check and trim if needed. I trim and chamfer the case clean them and neck size them if I am going to shoot them is the same rifle. if I am going to shot in another rifle I will full resize them. Each round I load is given a crimp both pistol and rifle. I use all Lee reloading equipment. I reload 380, 9mm, 38spl, 357mag, 40 S&W, 44 spl, 44mag, 45 acp, 45colt, 7.62x 51, 5.53, M1 carbine, 7.62x39.

I just wondered how accurately everyone trims their brass and how often.

After every shot with bottleneck cases - never with straight wall pistol. I use the basic Lee case length gauge & trimmer so I am limited to trimming to the prescribed length but it has never been a problem.

Sorry to pluck a quote out of a thread from 9 months ago, but I'm still doing my due diligence research on reloading, getting very specific to my situation, which is that I would start by reloading my Henry's only - 357 Mag, 30-30 and 308.

None of these beginner "Kits" come with trimmers, and BigAl has turned me onto The World's Finest Trimmer as the likely solution for my 30-30 and 308 trimming, but finding much online about trimming 357 Magnum for rifles is proving difficult. This thread, in fact, has more current info than anything I've found (at least from actual users).

I'll be starting out with a batch of NEW, unfired Hornady 357 brass (200 rounds), and about 200 rounds of once-fired 357 Fiocchi brass (that's been fired in my BBS).

The questions seem to be:
1. Do I need to double check all that new brass for length and trim anything over X case length?
2. Will I need to check the Fiocchi once-fired and trim it, too, if it exceeds some case length?
3. If Yes is the answer to 1 or 2 above, is there a decent straight-wall trimmer to look into, since it will be just for this caliber for now (I may look at reloading 45 ACP down the road, but no time soon)?

Seems like even many wheelgun shooters who can run into problems with 357s that are too long interfering with cylinder rotation never give trimming a second thought and never do it. Is the Henry chamber even more forgiving and I don't need to either?

Thanks in advance, as always!

Probably because few reloaders ever trim pistol brass. It does not ‘Grow’ like bottleneck rifle brass and if you use a collet style crimp die (factory crimp die) then length with pistol brass is not an issue.

The chamber length of most any pistol round rifle will be long enough to virtually never have a problem with untrimmed brass.

Thanks, Ed. I'll scratch this off my list.

Pistol brass like .45 A.C.P). or 9 mm that headspaces on the case mouth, need to be kept trimmed to specs.

Yep, I figured. Not crossing that bridge yet. For me, that'll be Reloading 2.0!

Do you actually trim all your.45 ACP and 9 MM you reload?
