BP Load Compression

Arcticap,

Great reading, thanks. It seems that those of us who use fillers i.e. cornmeal in my case, are delving into the unknown according to the author. I agree that care should be taken when choosing a filler but cotton balls, really?

thanks

Arctic: Thanks for that. It was good reading. Personally, I use Pufflon in my loads that require a filler. There is some anecdotal evidence that the cereal fillers solidify if left for a while (how long?) and may do more damage as an obstruction than as a filler. I have not had a problem with Pufflon in either my 45-70 carbine loads nor for the large 577-450 Martini case (a bottle necked case with a long neck and a very wide base). The latter is especially difficult to load with a compressed charge because of its shape.
Based on the text that you provided, the jury is still out finding a definitive answer to my question.
I do know that Cabelas sold - and maybe still sells - 577/450 BP ammo in which there is no filler and plenty of air space. I had some and dismantled them but I am still curious - as you can tell.
