This was touched up in one thread, but lets dedicate a current thread to this subject.

Here are the materials I use for fill or at least have on hand for fill.

1) Dacron fiber

2) Sill SEal

3) Cream of Wheat (COW)

4) Unused ground coffee.

I mostly use a filler in straight walled cases, such as 45-70 or 44 Mag, for those I punch out disks of Sill Seal. You can buy Sill Seal at the big box hardware store. In necked cases I use dacron fiber, these seem to work well, but when you are doing this work the load from the starting level of powder.

I have used COW in my 444 Marlin and 375 Winchester cartridges when I load them for my Contender.

Haven't tried the unused ground coffee yet, but do have a can of the store brand on my loading bench somewhere to try some day.

BPI has a fill media that I want to try, ordered so for my shotgun reloading, but may try it in one of bigger case cartridges when I want to make a light load. I am thinking about try this with my 300 RUM.

Any thoughts, ideas or experiences on this subject, I would like to hear from any who has tried this method or those you want to try this method.

 

Thanks,

Jerry

cream of wheat( malt-o-meal cornmeal etc) i have only used for black powder( on top of a over powder wad) and for fire forming ,i have reserved thoughts about it being loose with the powder especially since it doesnt ignite,when fire forming only when i am going to form then as opposed to later but there i use no wad i also usually fire form with a load in my gun ( no filler)
i have wondered every since i first saw u mention what kind of seal sealer, i have seen several kinds, from plastic/poly of some sort to plastic coated shredded"rag" types
while i love a variety of "reduced" loads i have always had an aversion to fillers and use them as little as possible,mostly in shotguns and black powder loads usually then fiber(cardboard type) or felt type wads,i have heard about various types of plastic etc etc but it always puts a picture in my mind of melted plastic fouling in my barrel, unfounded perhaps but i can never seem to shake that image from my mind ( i know it's just me lolz)

I only use two "fillers". Dacron fibers or toilet paper, the type of load determines which one.

One my gallery/plinking loads, I cut a square of TP into fourths and tamp it down onto the powder charge, usually 5.0 gr. of Unique with cast bullets weighing from 110 to120 gr.

My hunting (30-30) and targer loads may or may not get a piece of dacron batting used for quilting tamped lightly on my powder charge, usually 25.0 gr. of one of the 4895s with bullets weighing from 150 to 220 gr. in 30 caliber. (.308 Win. and 30-06)

I no longer use cereal fillers like Cream of Wheat (COW) or corn meal after i had to break down a round that misfired and found the COW pcked haed enough that I had to dig it out with a screwdriver. Imagine the pressures if that stuff packed that hard in a bottlenecked case. Makes me wonder if all those admonitions against using any type of filler came from using COW or some other cereal filler? :confused:

I use the Dacron in the form of batting used to make quilts. Just cut a strip half an inch wide and cut that strip in half inch pieces. Instant uniformity in weight. Normally I pick on either the 3.8" thick of 1/2 inch thick batting depending on the cartridge loaded. I find the 1/2" works better in cases like the 45-70. In other cartridges, one thickness or the other will work better. You just have to play with both to see which is better. Sometimes, no filler works better, but that's usally when the case is half full or more. you just have to tinker around and find out ich woks best.

A reloading buddy uses cotton wool when he does his 7.5 MAS (French) conversions by fireforming 6.5 Swede Mauser, capped in the case mouth with a bit of wax crayon.  It works well (using a light load of pistol powder) - but that burned cotton sure stinks!

I have read of corn meal and corn starch both being used.  I wonder if corncob media could be used as well?

Well now I remember where I got the toilet paper idea, Paul! I just loaded my first cast rifle bullet's yesterday and used about 1/4 sheet of toilet paper tamped down on each load. Worked great and as a bonus, I knew the bullet's made it out of the barrel because I could see the toilet paper floating away in the breeze!

The only time I have used toilet paper in anything that uses gun powder was a cannon on Independence Day. One roll of toilet paper didn't get tamped down enough or some other mistake in loading and every one saw a flaming roll of toilet paper going on a gentle arc thru the sky.

But TP is a good idea, I will have to try it.

Thanks,

Jerry

I actually used TP once, very early on (I was about 16 years old) when I wanted a low-velocity 'safe' load to pop mice in Dad's boathouse - it had a concrete floor, so I used a .22 pellet to replace the bullet in a .22LR shell with half the powder removed and the TP wad between powder and pellet.  My first 'reloads'......  :wink:

They worked - sometimes.  When they worked well, they'd penetrate 1/4" of pine, and would just splatter like solder on the concrete - no ricochet.  Most though would not get good velocity, some were squibs - very unreliable!  No mice fell to them either.

Imagine my surprise when, many years later, I find the Aguila Colibri loads - I thought, "Hey, they took my idea!"  Wish I could get royalties on it......  :lol:

I've always been suspicious of fillers, and haven't used them in a long time. I try to build loads, even low end stuff that doesn't need filler.

Don,

Yes it was pretty, a streaking fireball all a blaze and it was the good stuff.

I've been loading 11.15X60R (43 Mauser) for a few years now. I never use BP, only light loads of smokeless (3031/4198) with 387 grain lead flat nose. My 100 yard accuracy was so so. I tried a quarter sheet of TP over the powder charge and was amazed with the improvement in accuracy.

When different people started talking filler it made perfect sence to me. What it does is hold the powder to the flash hole and insure the same ignition each time. Without it, ignition would depend on where the powder was laying in the case. With a light load of some type shotgun powder I suspect the spark could go over the powder and ignite anywhere. If someone was using a large case with a light chg of some slow powder pressure can be raised dramatically on fireing if the spark jumps the powder and ignite's the front. Part of accuracy is consistent burn of the powder, it needs to be ignited and burned the same each time.

The fiber that is used for batting in quilts, stuffing for stuffed animals, ect makes good sence. What ever is used for batting, if it doesn't burn up, is going to change the weight of the projectile. That is not the bullet it's self but now the powder has to push the weight of the batting and the bullet, pressure will rise to some extent. The fiber's mentioned weight next to nothing so there would be extreamly little pressure rise. COW or similar substance is heavier and will raise pressure to some degree. Probably only an issue if your loading something close to max or using a very fast shotgun powder where small increments of powder will raise pressure quickly. Consider if you were shooting a 30-06 with a 180gr bullet at near a max load of Red Dot. Add enough COW to fill the case and hold the powder back and you will actually raise the weight of the projectile the pressure is required to push, that will raise pressure. Relate to a max load with a jacketed 165gr bullet being used to fire a 180gr bullet. You'll probably have more than you or your rifle can handle.

I found a stuffed animal in the shop yesterday that the mice have had their way with and might try the batting but, every house hold has toilet paper and a quarter sheet don't weight anything you could measure I think. Even if you ran out in the middle of loading your neighbor probably has some or the rest room at the gas station down the street. Toilet Paper what a wonderful product, I clean my glasses with it too!
