Howdy all, I'm just getting into reloading the 44 mag for my Ruger Redhawk with a 5.5 inch barrel.

I'm using Missouri Bullet Company's 240gr Keith bullets at 18 brinnell, Alliant 2400, Winchester LPP, and assorted once fired brass.

The once fired brass that I've collected so far all vary in case lengths. I'm thinking, it might create a problem when I seat the bullet, as the case must be crimped exactly at the cannelure of the bullet. And the cannelure may not line up exactly with the case mouth, since the brass varies in length.

If so which economical trimmer do you recommend. I'll only be reloading about 100 rounds at a time, so high volume is not neccessary.

Thanks in advance,

GlockMonk

If you want to trim them, I would recommend the Lee hand held case trimmer and .44 case length gauge.

I can also tell you that in 30+ years of reloading I have never trimmed any pistol case.

Good Luck

Hey Pye, How's it going?

I'm with Frankt - there are a whole lot of things in reloading in which require or you can befefit from detail, but trimming handgun cases is not one of them. Any amount of time you spend doing that is time you'll never get back.

I'd step up and buy the Forster Trimmer set up. Just starting out in reloading leaves a lot of life down the road. I bought mine in 1976 and it is still trimming those cases onesey twosey for me.

I have bigger more expensive powered Gracey's and Dillon's but the Forster steps up for things like the 6 PPC or any revolver like your 44 mags and some custom 357/38 Special stuff. I have a power adapter for the Forster that is readily available now and they are a great help even on 100cases..

Thank you everyone for the suggestions. I never bother to trim the 9mm, and 45acp, but then again, they don't have cannelures, and do not require crimping either :dunno:

Yep, I should really start reloading the 357, instead of the 44 mag. But that means I have to convert my 9mm set up; I just couldn't do it :embarassed:

Trimming is a bit more important on roll crimped rounds. And, a good crimp is essential on large magnum rounds. It's a good step to take with unknown brass. OP will only have to do it once. It will even up the cases and ensure a consistent crimp, less chance of damaged brass/projectiles, and the best accuracy.

After cases are trimmed, it would be a good ideas to chamfer/debur the case mouth. A Lee trimmer is probably the cheapest option for this one time operation.

I don't trim auto cases but I do trim revolver cases that I pick up at the range so that the roll crimps are firm and uniform. Lee hand trimmer is the most economical way to go. You can attach the shell holder assembly onto a drill and speed things up a little.

Thank you all for confirming the need to trim for large magnum revolver rounds for secure, and a uniform crimp. I shot my 44 mag reloads last week, and after the 4th shot, the bullet in the number 6th chamber was half way out of the case :wow:

I'll be ordering the Lee trimmer today, thanks.

I've only ever used the RCBS trimmer, but I'm thrilled with it, for sure. :supergrin: I've done a lot of .223 trimming, and a a bit of .44 mag, as well. I find the crimping process much more spiritually fulfilling, knowing that all my cases are the same length. :tongueout:

I only expand them enough to just barely get the base of the bullet seated by hand. Then I let the press do the rest. Based on the amount of force and whacks from my kinetic puller, I'd say I probably don't need to crimp at all.

I have a lyman trimmer... very handy to hook up a cordless drill to it when doing several hundred once fired / military brass .308's.


I'm unashamed for trimming mag rounds. It makes a difference. As noted, you usually only have to do it once...

Contrary to what others may say, that is caused by needing a more uniform and stout crimp. I made the mistake of undercrimping when I first started loading Ruger only loads for my 45 colt Blackhawk. Ended up with a jammed up revolver. Not going to make that mistake again.

I agree. A bit more crimp is in order. That is where the art in reloading comes in. Problem solving is a big deal for the endeavor. Just like not crimping 45 ACP enough and getting set back it is one of those things we learn experientially and hope nothing bad happens along the way.

I would argue that your taper crimp has nothing to do with setback in the .45 auto, neck tension does.

And in 45 ACP (or a taper crimp round) you would be arguing correctly. :thumbsup:

Sorry, probably a discussion for a different thread.

So taper crimpers have no impact on neck tension? What do they do then if they don't?

They eliminate the flare and allow the round to headspace on the case mouth.

Actually, too much taper crimp can adversely affect neck tension.

I shot some 45 ACP at an Area IPSC match in Dallas in 1986 and had reset my taper crimp after cleaning my dies . A normally great load was actually tumbling the bullets. We were shooting H&G 68's 220 grain SWCL's.

I believe at that point I did learn about neck tension and the 45 ACP. LOL I had learned about taking out the flare on a 45 case with one about 1980 when I got into IPSC shooting in a big way.

Think of the shape of the inside of your taper crimp die... larger getting gradually smaller. Over tighten it, and the brass has to go somewhere - it gets pushed down expanding to the dimensions of the larger part of the die. Smash the bullet at the end, and almost no grip a little further down the bullet. All you want to do is take out the flare you put in it a stage before...

If set too tight (ie incorrectly) they can decrease neck tension.

Funny how some lessons stay with us. Many of mine have been learned the same way.
