    Can you skip the step. It is faster on a few loaders?

    Get a Mec grabber, it resizes every shell you reload. If you reload shells from any gun but your own you need to resize , as all chambers are not the same size. Especially if you reload the steel based shells. Roger C.

    If all your hulls were originally fired in your gun you could probably skip the step. Consider though whether using one or two piece hulls that even a minimal resizing takes your base back to a firmer contact with the tube and whatever basewad it might contain. The resizing operation on my 9000H is part of the depriming stage so there is zero difference in time by not sizing. The sizing collet is infinitely adjustable so I set it to resize .001" or .002" over the unfired dimension........ Larry

    I resize all the steel-base hulls I reload (which is most of them)with a MEC Super Sizer because it takes a lot of stress off my PW presses. The PW was designed around brass bases. Brass is soft. It's a lot harder to stuff a steel base into a ring sizer... and even harder to push it out again at the end of the cycle.

    10-4 to what" mah66" posted above. If you persist is reloading these kinds of hulls, use some lube on the dies.

    Not only are steel based hulls like Kemen's, Rio's, etc. hard on reloaders, they are equally hard on gun chambers. When a brass based shell is fired the brass relaxes a bit making it easier to eject from the gun's chamber; whereas steel does not "relax" so it scuffs the chamber as it is ejected.

    My good friend Kerry Allor says he loves the steel based hulls because eventually he get to sleeve chambers.

    you can skip resizing if you only shoot one gun. if you shoot more than one gun then you should resize. because you got better odds of hitting the lottery than both chambers being the same size. it will only take a couple ten thousands of a inch and you will need superman to put the shells in the gun.

    Give the barrel a ker thunk on the concrete between shots. Works great. Ask Shaeffer.

    Whether or not this is true is going to depend on the gun, hull and the press. If you have a press that does NOT resize the bases as part of the reloading process than you can probably skip it. But I have a press that resizes and uses ring sizers to do it. There's a difference of about .006" between the ID of the sizers and ID of the chamber (the chamber of course being bigger). That leaves the steel hull base .005" larger across than the sizer. That's a heck of an interference fit between the two and it only makes sense to reduce the diameter of the hull base some with a separate sizer before assigning it to the press.

    I have never resized. Use a PW 900 and before that an PW 800C. Steel or brass and have never had problem in federal shells. They work fine in all my guns. Browning, Beretta, Perazzi.

    I found that if you use the same gun I did not have a problem not resizing. Now my Dillon SL900 resizes all as part of the normal operation.

    One of the men I shoot with has reloaded for 30+ years without resizing..... only has cases stick in the chamber once in a while... I have always loaded with a unit that resizes...... never had one stick. He makes sure he has either a wad knocker in his pocket or a rod at the scoring cart... but I carry a wad knocker too, just in case.... Larry

    Good question. I resize using a Mec Super Sizer. You can resize a bushel basket of empties in no time. Put if you are going to shoot the reloads in the same gun every time I "might" skip it if you are in a hurry.

    Elsie.
    If you only reload you own empties, you can skip the sizing operation. If you buy or pick up shells from the ground you should resize. If you have a gun with a tight chamber, and you get shells from a pump or semi auto, not resizing could be a problem for you. Roger C.

    That's USUALLY true with AAs and STS. It's often NOT true of other hulls, especially steel rimmed hulls.

    If you are using a PW, you ARE resizing.

    Use a Mec supper sizer -- Don't know if they need it-- but it gives the grand kid something to do ----------- Hope they don't go bragging about loading ammo To their teacher --We all will be in jail

    My first O/U had very tight chambers. I was using a lot of once fired hulls, so I purchased a MEC Supper Sized on all my hulls. If I'm loading for my Stoeger Grand, I don't have to size each time, but it my wife is Shooting he Win pump trap gun, they need sized. So, I just size everything and don't worry about it anymore. JMHO.

    Might depend on how many times you would reload/resize and what hull being used. Most straight wall hulls are a metal base, some sort of base wad and an open ended tube for the body that I suspect depends on a certain amount of "squeeze" to keep thing together..... I have observed a few base extractions without a hull or basewad attached..... I would guess that once or twice through the press a shooter would be fine but perhaps after that there is a bit of jeopardy involved??? Larry
