44 mag revolver case length

im sure this has been discussed plenty of times but im somewhat computer illiterate. so heres my question I have some mixed range brass I measured out 5 of them right at1.275 which is what is recommended from what I found they are all loaded and measure out at max oacl or just under. now the ones that are a bit longer can I get away with seating just a bit deeper ? I don't have a trimmer as of now . and the shorties can I use them for 44spcl? thanks.

nashville lpd 13, The text book length for 44 Mag brass is 1.285" and the trim (minimum) length is 1.275". Make sure you measure AFTER resizing!!! Brass length itself does NOT dictate the overall length of a cartridge, it is merely a condition of how deep you set your bullet seater die. The bullet's cannelure or crimp groove is wide enough to accommodate max or min case length so unless your brass is way too long or too short, it should end up being within COL specs as noted in your reloading manual for the specific bullet you are loading. Crimps will be much more uniform when all brass is the same length. That said, you can sort your brass into batches of equal length if you don't have a case trimmer, then adjust bullet seating depth and crimp accordingly for each different length. Typically, if case length is within .005" of spec, it should load and crimp just fine. For this reason, I like to trim my brass to .005" shorter than SAAMI max or in this situation, 1.280". That gives me an acceptable spread from the minimum trim length of 1.275" to the max SAAMI length of 1.285".

You can load any 44 Mag case to 44 Special power levels .... a very common practice for reloaders. Just don't expect the loaded cartridge to chamber in a 44 Special revolver. 44 Specials have a max length of 1.160" and a trim length of 1.150" .... .125" shorter than 44 Mag brass. Of course the shorter cases loaded to 44 Special power levels will chamber and safely shoot in any 44 Mag revolver.

thanks that explains it very well I measured my 5 I finished up after seating and all are within spec. now can you answer my other question I posted about 200 gr xtp over 11.5 gr unique? its the starting load in my nosler manual for a 200 gr jhp

When I go home in 2 hours I will pull out my Hornady Manual and give you the load data on the XTP's with Unique. Hornady will have the correct info.
Hang tight,

nashville lpd 13, Unique is a mid-burn rate powder that can be used in a host of different cartridges. It is seldom the best powder for the application but it will indeed work. In a 44 Mag, Unique is great for loads in the 1000 fps velocity range but it is a poor selection for full power loads. Slower burning powder such as W-296 or its twin H-110 is about as good as it gets for highest velocity and best accuracy. Unique burns too fast for 44 Mag higher velocity loads and develops much higher chamber pressure in the process.

The Hornady manual's range for Unique with a 200gr XTP in a 44 Mag is 11.4 gr (1300 fps)~12.9 gr (1400 fps). Personally, I wouldn't recommend loading this hot with Unique but it's your gun. 10gr runs about 1000 fps with this bullet and is well under SAAMI max limits .... a nice mid-range load. Using H-110, you can easily get 1500 fps with the same bullet while chamber pressure is about the same as 10gr of Unique.

One issue that comes to mind is .... accelerated wear in guns is directly linked to high chamber pressure. It's like running your family car day after day at 90 mph. It may take it for a while but eventually high speed will take its toll. The same car run at 70 mph will keep running for many more total miles and will be much safer to operate .... just like running lower pressure loads will extend the life of your gun.

Case length is NOT critical for handguns. I have never found any of my handgun brass to lengthen over time, not even cases that I have been firing for 40 years.
Many years ago, I trimmed some of my .38 Spl, .357 Mag, and .44 Rem Mag cases to the SAME length so the roll crimp would be more consistent. After firing many times with matched head stamp and length cases vs range mixed brass for all, I found even in my S&W M52s that it made NO difference. In fact, just like my many tests for matching head stamps, the avg. group size and S.D. was very slightly smaller for the MIXED than the matched (though, using a student t-test, the null hypothesis that they all came from the same data was was accepted at the 95% level.
The only thing I found that affected accuracy was the use of Redding Profile Crimp Dies for roll crimping vs std roll crimp dies.
It wasn't worth any additional time. Neither was primer pocket cleaning for any gun, handgun or rifle.
If you want to get good, you need time behind the trigger and not time behind the reloading bench.
