Where to buy polysphyrical buffer media in canada?

[julesr]

I've been doing a lot of cast bullet reloading in rifle rounds lately, and have been thinking about which filler to use to fill the void in the cases due to the reduced powder volumes.
I've been reading that people use toilet paper and dacron, but both seem tedious. the poly spherical buffer seems the best choice but I can't find where to get it.
thanks

I believe Phil Bilozir carries the plastic buffer stuff. It is primarily used as a buffer in shotshells. I would only use it in straight walled cases (I have a jar of it but haven't tried it yet) if I were going to use it in rifle shells. I would fear that it would increase pressures in bottle-necked cases as you would basically be trying to force a plastic plug the size of the case body through the much smaller neck (just my theory anyways).

I have used the Dacron squares with no problems and don't consider the added operation much of an inconvenience at all.

Thanks, that is just the insight I come here for. where does one get dacron squares? I thought people literally just pulled stuffing out of pillows etc

You can purchase it at any fabric store, very inexpensive $5 will buy several lifetimes worth I think. It comes to them in rolls about 60" wide by 1 in thick so you just buy a cut of 1/2 or 1 sq. yrd, whatever floats yer boat and then cut it into 1/2 to 3/4" squares (takes 5 minutes) depending on how much space you need to fill. I just place the chunk over case mouth and give'r a push with a pencil so it is all inside the case mouth then seat the bullet (that will seat the Dacron against the powder and bullet both).

Sound good to me. I'll give it a try thanks

I personally use "Teddy guts".

Anyone who has a dog or two knows what Teddy Guts are (the fluffy stuff that gets ripped-out through the eye sockets)

As finngers284 sez, if you use Dacron be sure that the Dacron touches both the bullet base and the powder or you might ring your chamber rendering your rifle useless..
