Wads?

Post by .22-5-40 » Mon Mar 09, 2015 8:26 pm

I have read where a good thick wad is needed under a patched bullet to hold the gas back. But, if you can only chamber a bullet of bore dia. (land-land) or perhaps .001" or .002" over, how then does this undersized wad seal off the gas? Do veg. fibre wads expand? if not, would a cork type wad either by itself or in combination with a veg. fibre wad be better? What about 1/32"-1/16" thick pure beeswax wad under 1/16" veg. fiber wad..or sandwiched between? Sorry for all the questions, but lots to learn. Thanks!

I use a .460" Walters Fiber wad usually. I do NOT use undersized wads with bore diameter bullets. Lately I've been using some LDPE wads of approximately the same diameter. Some folks wrestle a bit with getting these in the case mouth of brass from very tight chambers, but after awhile, it gets pretty easy.

I played a little with LDPE wads of different sizes. In my .45-70 I tried .450" diameter wads an accuracy was reduced along with a few burn marks on the patches. Going to 0.454" diameter 0.060" LDPE wads works well in my .45-70, but in my new .45-90 I just recently found a few light burn marks on a couple of patch remnants and have now switched back to 0.460" diameter wads. They are a very tight fit as they larger than the inside dimension of my cases, but they do seem to work better.

I don't get a good gas seal with a veg wad, but then I have a different chamber design than Brent. The .45-70 will shoot with a 0.060" veg wad, but not very accurately. If I try that in the .45-90 it becomes a lead mine :-).

One other thing I've found is that you can use too much wad. Twice while experimenting with a few loads that shot well, I added an additional wad ( one was rubberized cork gasket, and the second time was a thick felt wad ), and found that accuracy immediately disappeared.

My wad stack for a PP bullet is a OJ carton wad over the powder a thin lube wad 1/8" or less to just more or less to lube the case neck to hold down the stretching I get not using a lube wad and a 1/16" dense cork wad under the bullet. I personally don't like the rubberized cork gasket materials.
For some reason my .50 does not do well using a PP bullet so it gets a GG with a 1/16" cork under the bullet. I get a very low ES in the low single digits with these combinations in standard and tight chambers.

Do you define 'tight chamber' as one which will only accept bore diameter bullets?

My tight chambers will not except a groove diameter bullet, PP or GG.
So yes I define a tight chamber this way. A tight chamber is designed for the brass I use that will just except a bullet (GG or PP) in a unsized case that has a snug fit inserting the bullet in the case.

Where do you get the cork for wad material?

I'm probably going to use the rest of my rubberized cork for making gaskets :D.

I used to get it at tractor supply co. but they quit stocking the fine ground dense cork and started stocking the courser rubber cellulose stuff so I'm looking for another place. I'm going to order a couple sheets from here soon to see how good it is. http://www.cleverbrand.com/default.aspx ... aQodknwAmQ
