Trimming .30 Carbine brass

[moranna]

My BIL is a 30 Carbine fan but plinking ammo kind of pricey. He's not a reloader so agreed to help him out.

Almost every case is over 1.290 after resizing. I have never trimmed straight wall pistol cases but do use the Frankford Arsenal trim station for bottleneck rifle (indexing off of the shoulder).

My question is, can straight wall brass be trimmed with the Frankford? Have a Lee length gauge trimmer on order but would like to use the Frankford if possible so I can deburr case mouth and ream crimped primer pockets at same time.

Thanks

My impression is that the case needs a shoulder with the Frankford. Set the 2 machines up side by side and go to town.

I like the Lyman hand trimmer with the cam lock case holder.

I've tried several lathe type trimmers to trim 30 carbine and they were less than ideal. An RCBS trim die is the quick and painless way to do it as far as I'm concerned.

Buy this and screw it into the unused station on your Trim Center:

If this isn't what you already bought, buy it too:

Put the Case in the case holder, trim with the lee .30c Trimmer you just made, chamfer, debur, profit!

Other than the need to use the shell holder, it is about perfect. I have not tried using one of these yet:

But I suspect it will make the shellholder pain less than it was.

Thanks Maxx. I bought the case length gauge but the other two parts should let me use the Frankford unit.

BIL had accumulated about 500 pieces of brass and a lot it must have been from old surplus. Some of the brass had pimers so tight the Lee resizer die could not punch out no matter how snug the decapper rod was.

Just happened to be watching "The Pacific" on Netflix this week and noticed that a lot of the Marines were using the M1 Carbines.

Maxxhavoc has it exactly right.

The primers are likely locked in place with corrosion.

I watched that recently along with a few other WW1 and WW2 movies along with the Highwaymen. Love seeing those older shows and id'ing (is that a word?) those older weapons.

But to keep the thread on track I use a Lyman trimmer with the universal chuck to trim 30 Carbine brass. Also on what pistol brass that I trim.

Not really, as it's "identifying", ID being an abbreviation for Identification (or identity) Document(s), like show me your ID. But it works and everyone knows what you mean.

Once you get that set up, please post a picture. I'd like to see how that all fits together.

Have you checked that some of that surplus might be Berdan primed? I know a lot of M1 carbines ended up in Europe after the war to rearm allies, so it’s possible that’s your hard primer problem.
