	im.shooting a small tapered 357 necked to .25 and having a time not spilling powder in the chamber I have used Blue foam sill sealer material and it shot worse. I really need is something over the mouth of the case so the powder doesn't spill I also tried little washed out of cardboard milk jugs on the end of the neck and accuracy also deteriorated. ideas?

	1/16" Thick Cork punched out to a diameter that will cause it to become caught in the mouth of the case. If you use a 1/4" leather punch and stamp on a piece of hardwood on the end grain it will most likely come out a good size. The leather punch will crowd the Cork as it is punched thru and come out a good oversize to be a good fit in the mouth of the case. With a case that small putting a wad right down over the Powder would have the potential of causing a high pressure. I use 1/16" thick as a powder retainer in 32-40 in this manner, it keeps the powder contained nicely and the wad lets you handle the loaded cartridge and not dump powder into the action.

	Indeed, the floral foam. BUT: Floral foam "sheets" need to be cut from blocks of the stuff. I found an altenative that seems to be working for me in 25-20 and in 32-40 Rem Hep: Fan fold Foam House wrap that is installed under siding: It is about 1/4" thick, same polystyrene foam as floral foam. I had some left over pieces of it from a siding job I had done years back. And my son, who is still in construction provided more. Just "cookie cut" with your powder filled case. It helps to do an inside case chamfering. beltfed/arnie

	I use the vegetable wad material and cut it with case prepped as it would have been to shoot, except for the primer pocket that is drilled out for a push rod to remove the cut wads. Wads placed at the top of the neck. I noticed a huge difference with bullets that are marginally stable based on the twist calculators.

	Be veryt careful of plastics as many of them can melt and leave a good residue in your throat that is very hard to get out. Even floral foam has two types one good one bad. I have used Cork for over 40 years now and have never had a problem. I have also experimented with Wool felt. You can get felt in rolls to punch out. For less than 5 bucks you can get about 1/16" cork sheets in rolls that will give you enough wads for a couple of years of shooting. 40 Rod
