I realize you can omit the resizing process when re-loading for the same rifle.

I notice my spent 38 Sp rounds would chamber in my revolvers. I'm not using hot loads -- 2.7 gr Bullseye under 105 gr Lee truncated cast bullet.

Does anybody omit resizing in pistol cartridges? 

I realize that cylinders on the same wheel gun might not be the same, exact size.

Thought I'd ask before I tried loading some.

You are mistaken.The case of a rifle must be resized to hold the bullet.Neck sizing accomplishes this with a neck sizing die if the round is to be used in the rifle it was originally fired in.
Otherwise full length resizing is necessary if it is to be used in a different rifle.
Pistol cases must also be resized.Sorry bud,no getting around the resizing thing:wink:

Agree with Timbeghozt.

neck sizing will pretty much always be necessary.fl sizing will be needed when the case wont fit into the intended firearm.i bought 200 once fired cases for my 270.i tried every one of them.neck sized those that fit and fl sized the 25 or so that didnt.neck sizing works the brass less.hopefully the case life will be more.

I realize that neck sizing is always necessary for all reloading.  I don't know how I'd neck size pistol cases without full sizing.

I have not had this thought before so I've never messed with a straight-wall sizing die.

Upon  mature reflection, nothing would be gained as the case would still have to be handled for neck sizing.  Pistol cases are cheap enough that case wear is  not be an issue.

But, I do hate sizing cases.  I still remember changing over to carbide dies.

Thanks.

There may be an exception. Some tight neck application does not require any sizing.

At some matches I have been to competitors just deprime, reprime, charge and seat a bullet, fire and repeat.

Ditto 72, Bench rest rifles have chambers that are precisely dimensioned to their particular cartridge. I've even heard of some guys hand seating their bullets long and by simply chambering the cartridge the bullet will seat itself against the lands of the rifling. Their loads are accuracy loads, not velocity loads.

On all of my rifles I partially resize by using Full Length dies that I back out of the press appox. 3/4 to 1 full turn off of the shell holder. The rule being to resize the neck at least one half of the bullet diameter - minimum. This reduces case stretch considerably. The only exception to this are my two WSMs. These I full length resize.  When I work up loads or sight in, or just play, I generally use the same 6 or nine cases over and over until I start getting work hardened necks with splits. I have lost count as to how many times these cases have been reloaded. But I do inspect the cases thoroughly before each reloading.

Rifles you need to at least neck size, with straight cased pistol cartridges I can get buy with no resizing, but then have to use a crimp die on the case to keep a good grip on the case.

@ Jerry;

Where then is the profit, the crimping process puts, I think, more strain on the cases then resizing.

Regards,

Paul

Paul,

I generally resize, but some times I don't and instead of a roll crimp, I use a taper crimp.

Neck sizing pertains to rifle bottleneck cases only.  I looked at the major manufacturers of reloading dies and no one offers neck sizing dies for pistol

Desert Marine,

Do you want a neck sizing die for any specific pistol caliber? I can make one up in my machine shop, maybe CH/4D would make up some dies for you,

http://www.ch4d.com/

 or you can get a hold of Fred Huntington's company, they will have one made for you:

http://www.huntingtonsports.com/specialinterest.html

I have used some cartridge conversion dies to do a slight neck sizing on a couple of pistol cases to get things back into spec for a special project I did about 6 or 7 years ago. It didn't make any change to the cases that was recordable.

Jerry

No, I was just pointing out that I had not seen neck sizing dies for pistol cases.  Thanks for the info anyway.  I cannot see where neck sizing pistol cases would help but can see where full-length size is better.  Chambers in a pistol are not always the same size, so what might fit in one chamber might not necessarly fit in an other chamber without resizing. 

Thanks for the links.

DesertMarine,

I shoot T/C Contender, they are single shot pistols in various calibers, some shhot 22 hornets and others shoot hand cannon type straight walled cases. This is where possible a neck sizing could be be needed or used.

Jerry,

I am familiar with T/C pistols and the many calibers that can be fired from one.  .357 and .45ACP are about the only straight-walled cartridges that I reload.  No problem with sometimes some calibers might benefit from neck-sizing.  I shoot revolver and semi-auto and there I do not see a benefit for neck-sizing, especially in a revolver.  In a single-shot like a T/C, and some calibers, possibility. 

I am not trying to belabor or argue the case, I am curious.  What hand cannon straight-walled cases would benefit from neck-sizing?

I was going to go into T/C pisotls at one time but decided on a Ruger #1 instead.  Not the most accurate but one of my favorites.

444 Marlin, I just do a little neck sizing and they work well for me in JDJ barrel on my Contender frame.

i always resize every case i reload be it .38spl, .357 magnum or 9mm....  just makes sense to make the best ammo you can and resizing is part of it... i also consider reloading a hobby and like to spend as much time at the reloading as i can.....   i've been thinking about getting one of the lee universal flareing tool so i can have even more to do to a case!   

                LIFE IS SHORT.....

I have two of those Lee mouth flaring tools, one I use for small caliber and one I use for big calibers. I also have one that I made up in the shop, from an old Lyman mouth flaring die.

 

They are a big help in your reloaidn and gives you some more control over the process for reloading.

 

Good Luck,

 

Jerry

DM, it may not be a hand cannon, but my T/C S14 in .45 Win mag gets sized only far enough to hold the bullet. I find that after firing, the case has conformed to the chamber, and full length sizing works the brass too much for long life. Good shooting :thumbs:.

3006 User,

I agree with you on the 45 Win Mag, I have one of those barrels also. I only size the first of the case, like you said, just enough for the bullet.

With my 357 Max barrel, I only size the first part of the case, like before just enough to hold the bullet, plus this was a revolver catridge when it came out. It's a darn nice cartridge in my Contender and great for hunting.

Jerry
