This is for hand gun reloading only. I reload for both .357 and 44 magnums. Is there any advantage to maxing out the case length? I always trim cases, but was curious as to why we don't want the bullets seating closer to the lands as possible with handguns as we do with rifles. I reloaded .357 yesterday and have a c.o.l., 1.578 for my 140 gr hp/xtp and a c.o.l., of 1.581" for the 158 hp/xtp. Hornady's manual says that I can have c.o.l. maxed out to 1.590". I am curious about the 44 as well, as I reloaded some of those last week as well, thx

Here's my thoughts on it. I don't worry about it at all. A handgun isn't that so accurate that worrying about getting it closer to the lands is gong to be noticable, so why take the time. I don't trim my brass either. Again, for the same reason. Just my thoughts.

they have to fit inside the cylinder for it to be able to revolve.

Especially in a revolver, that extra .01" is not going to mean mean Jack since it still has at least a .06" barrel/cylinder gap to go through PLUS the the forcing cone, before it sees the lands. HOWEVER, what keeping them trimmed to the same length will do is to make the same crimp and same crimp weight on every bullet the same. Some may not think it makes a difference since pistols aren't as accurate, they would be wrong though, sorry. I come from a L O N G barrel (S&W) family. A 6" pistol is a "snub-nose" to us. :crazy: My dad taught us to sight our pistols in at 75 yards so we had little hold over/under at 50 & 100 yards. At that distance, you can really tell how much better they shoot with detail paid to some things. Years ago (dumber and more broke) I never cleaned, and hardly trimmed my brass. I would also seat & crimp in one stroke. Not any more! As I paid more attention to detail, the groups shrank, significantly, with each "new" step taken. Especially the seating and crimping as two different steps. If you have concerns about seating the bullet closer to the lands for accuracy reasons, then you should also have concerns about having the same length cartridge for all cases, as it will effect the crimp and the accuracy much more than COAL. So keep them at whatever length (within tolerances) you want, but just make sure they are all that same length. Hope that makes sense or helps.

Thanks, all my reloads, depending on bullet all look the same. I like all my reloads to be identical, just wondering if I can get them closer a bit. Thx

I hear ya. Lever guns are the same way. If you load them long trying to decrease the land gap, they won't cycle. Best thing you can do also is to make sure the cast bulet is definitely larger than the bore, and use a bullet with most (longest) contact area (body) for best stabilization. This is what makes wadcutters so accurate.

Gotta have something to do when the birds aren't flying, right? :D Actually, pistols and are what I cut my teeth on W A Y back when. I used to reload in Jr. High ('80's), and almost all of it was pistol back then. Pops would only let us shoot what we reloaded. Smart man. I'm not what most refer to as a "pistol guy", but I do know them well. We are a long barrel N Frame S&W family (27, 28, & 29's). I don't believe I need most of the calibers out there. There is nothing in this world Thunder (Model 27 .357 8-3/8) & Lightning (Model 29 .44 8-3/8) can't handle. And my beaters are a 686 snubnose (6" barrel) and a .40 S&W. It took me a long time to decide between a .40 or a .45, since we are not an auto family. Give me the .40 with ten rounds and better ballistics any day of the week though :yikes[1]: So yes, through trial and error and blood, sweat, an tears, I do know pistols. :D The twins, Thunder & Lightning. (Thunder makes the noise, but Lightning does the work) Along with my two other favorite things in this world!Posted Image
