Filler Question.

[tacfoley]

i dont reload bp this way but a few lads i know from another forum do..
basically they load martini henrys with 85gns of bp with no filler other than the grease cookies and cards in the neck.
they say mr greener and others said leaving up to 20% air space in a cartridge was acceptable with no issues.
these are not my words but others

Please go right ahead and try it out for us.

We are eager to see your results.

BTW, loading 85gr AND grease cookies in a .577-450 doesn't actually leave ANY airspace, in my experience, at least. YMMD.

20% air gap? Might be OK. But basically the practice of leaving a LARGE airspace between a bullet/ball and load WILL result in damage to a BP firearm, ranging from mild ringing to catastrophic failure of the barrel at just about the point where your hand is holding it. Did you even look at the CVA YouTube movie?
