	Looking to try some light loads for my 40-70 and was wondering how do you fill the air space between the base of the bullet and the charge of bp? Shooting fixed loads. Tom

	Bulseyetom, I shoot my 40-70SS with 50 grains of 1.5 Swiss and a 340 grain PP bullet for offhand. I use cork wads I punch out from 1/8" cork gasket sheets purchased at the fleet farm store. If you are shooting gg bullets it just takes less wads. Keep on hav'n fun! MikeT

	Best filler for BP loads is amaranth seeds that you can get from health-food stores. They are about 1mm hard seeds that meter well from a powder measure. I dump in the powder, dump in the seeds, run into a compression die, then seat the bullet. Probably all the ranges will come up to amaranth plants in the spring. CHRIS RGChristensen

	Just enough 1f in the case to make firm contact with the bullet base.

	Are amaranth seeds approved in California? I don't want to get arrested for introducing a non native plant! Tom

	The best filler for black powder is air. Providing the case is at least two thirds full, you will get good, uniform ignition. Many British black powder rounds were loaded with air space, but at least a hundred years ago somebody decided that it was bad practice and this view became widely distributed and repeated. It is rubbish. Fred

It is rubbish. Agree with Fred ... when the Open Range forum was up, we had a long multi page discussion about air space. The were many pictures of old commercial ammunition that were cut lengthwise showing air space between the powder column and the bullet base

It is rubbish. Fred Fred, you have hit the nail fairly on the head! The fear of air space has carried over from the Italian percussion Hawken rifle craze started in the 1970s here in the US. The average shooter tends to go by what he or she hears, not the facts. Have tried all sorts of BP loads with air space. No luck ever. Got turned on to Puff-Lon. Could use my 45-90 chicken loads for Schuetzen matches if I had a rifle with the correct configuration. Mild recoil and very very accurate. Dave Casey has shot his 32-40 with air space for years, no problems.

	Westerner please expand on how the Italian percussion Hawken rifle craze back in the day got us here believing no air space is a must. I learned my BP cartridge loading from Venturino & Garbe's's book back in the 90s and even have a TC Hawken and was sdurrpised as heck. Though I often wondered how breech seating could possible preclude any air gap at all. Thanks

	Expand? Let's make it easy for me. What don't you understand? What do you want to know?

	Is it that not seating the bullet on the powder in a muzzle loading barrel of inferior metallurgy could lead to a bulge or worse?

	the late george creed of Spokane wa ran some tests in muzzleloader barrels with space over the ball.he was unable to bulge barrels even when he thinned them.down very thin.he made a crude lead crusher pressure tester and was unable to notice anything odd with the ball having a space over the powder.
