Bob-
It ends up being super simple with the dacron.
It's especially nice for bottleneck cartridges.
I use firm pure wool felt and sometimes cork for my heavier bore rifle loads.
I weigh my charges of dacron for each run of cartridges I load, bag them in little ziplock bags, and set them aside for the last stage of loading before I seat the bullets.
I have scores of images from old books and catalogs showing the bore rifle and big express rifle loads indicating solid fillers used to fill any void between powder and bullet.
Kynoch offers a spongy foam wad product that some guys run in Nitro for Black and Full Nitro loads.
I've spoken to guys who have encountered chamber ringing using foam. Never heard of anyone hurting a rifle when properly using the dacron -- and by properly, I mean that one must use enough of it to have it firmly compressed against the powder, filling all space between powder and the bullet base.
My loads run dacron directly against the Varget powder, with the jacketed bullet keeping tension on the dacron.
Some guys complain about the 'mess' that comes from shooting these loads, in that the dacron doesn't burn or de-compose during the shot.
It ends up landing on the ground ten or so feet forward of the muzzles.
No residue on the rifle or in the bores at all, but the hassle of picking up the dacron at the end of the shooting session is enough reason for some guys to use the Kynoch foam wads - which seem to dis-integrate during the shot leaving no residue in the rifle or on the ground in front of the rifle.
Something to consider if you don't like cleaning up at the range...
Cheers
Tinker
