Default Definition of tedious...

Just a bit of a rant.

But yesterday and today, on and off for quite a few hours i have been trimming 45 acp brass to .888 and cleaning primer pockets.

I dont have one of those fancy smansy auto trimmers or anything like that, all i have is a lee case length gauge, trimmer, shell holder, cordless drill, chamfering tool and primer pocket cleaner.

What a PITA!!!

That is all...

( I do have a fancy machine but it only deburrs and cleans primer pockets..)

fmj, I feel for you.

I trim all of my .223/5.56, .308/7.62 and 30.06 every time I load them. Have a back log of maybe 4000 cases now.

Why are you trimming .45s?

I never trim 9s, 40s, 44s or 45s. I don't think I would ever want to start that... Well, except when I cut down 44 mags to specials or make 44 mags out of 303 Brit brass. But that is seldom.

well, i have learned that the 45 acp head spaces off the case rim/mouth. Manual calls for a case length of .888" alot of this once fired brass is upwards of .895. I figured it would be best to tumble, de-cap, trim, de-bur and clean primer pockets on ALL my hoarded .45 acp brass....starting with 200 at a time.

Will be starting the .35 Rem. 30-06 and .223 chore soon enough. Need to get case length gauge for 30-06 and .223....i am thinking a zip trimmer and case prep station would be money WELL spent.

At this point i have yet to worry about trimming .357 or .44 mags since it is rimmed brass and will chamber fine even if case length is long.

fmj,

I have shot 10 of thousands of .45s and re-cycled a lot of that brass over and over and over and never had any problems. I used to put a role crimp on my .44s and that required a consistent length. I don't do role crimping any longer, so I don't trim them.

I trim most all of my rifle brass. I run .223/5.56 and .308/7.62 and 30.06 in different weapons including auto-loaders.

So, it looks like you are as nut as I am. My .308/7.62s are loaded soft and little is trimmed but I still do it every loading. My Garands and 03A3 stretch brass and I get more trimmings from them.

If you trim your .45 ACP cases to .888, you are creating 0.01" of excess head space. Remember, on a straight-wall case, your case length is what controls head space. You also probably have a lot of cases that aren't even that long.
Why would anyone create excess head space if they don't have to? You should have a goal of finding and keeping ALL cases that range from 0.894-0.898" for your most accurate/target loads. Thankfully, unlike 9x19, the .45ACP isn't that sensitive to case length and even the short cases shoot accurately.

I have loaded and shot thousands of rounds of .45 ACP ammo. I have NEVER trimmed them. The .45 is a very forgiving cartridge. Trimming is a waste of time (IMHO) on pistol cases.

Tedious is turning .270 Win into 8mm Mauser. Aneal, progressively neck up to .284, .308 then .323, Full length size in 8mm die, trim 6mm off with dremel, then square it up on the Forster trimmer.

I have never trimmed .45ACP brass in the 30+ years I have been reloading. I have never experienced any problems that were the result of cases being too long. I also think trimming .45ACP cases is a waste of time.

FMJ, i feel your pain. seemed to take me forever last week when i was cleaning, de priming my .40 shells. i'll admit i wasnt trimming them. but i was wiping them all down before i put them into my die. and let me just say theres not a spec of old powder in that priming pocket. haha. took me a couple hours a day for three days to get 420 rounds done. lol

Thanks for the replies here guys. I trim to .888" because the manual says the case length should be .888". Being rather green to reloading (Have only done a thousand or so .357 and 500 or so .44 mag and a hundred or so .45 acp) what the manual says, fmj does. normally....

but what you are saying makes sense to me considering a lot of the brass is .894-.898. Some is shorter...little is .888". I didnt think once fired would stretch THAT much from a .45. Most of my brass is Win. with some CCI tossed into the mix that were factory loads i bought and saved for years before i started reloading

The decapping isnt so much a chore and cleaning the primer pockets isnt that rough when compared to trimming...i'm not cleaning the inside of the case! I let the tumbler and polish do that...I figure thats good enough for Govt work.
