Agree with both of you.
I did look up Bill and read a nice article RW had with him. Also, learned that APP is Jim Shockey's stuff.
BP burns at a continuous and faster rate, that is why we have different F granulation. We know 4F is the fastest burning because and has the smallest amount of surface area (and size) with each grain, therefor each grains burns up quicker compared to 1F.
Smokeless is progressive and dependent on each other grain to generate and accelerate burn, that's why the more of it and pressure it has the better it perform (cartridge - no problem with ignition). I think this might be the root cause of why we're seeing some ignition issues with it and BH209 in a ML. Without the interference fit of the bullet/sabot, that is where the problem lies (I believe).
1) Because of the rare instance it does not ignite, the force of the 209 primer will move the bullet. (We all have agreed that all ML maker state bullet off powder can cause the barrel to burst). But, since (I THINK - big, I THINK) the previous #11 and BP and subs users are NOT used to or ever experienced a bullet moving. Then they experience this non-ignition with smokeless, they just re-prime and fire another without knowing the bullet has moved off the powder.
2) The guys who see the bullet exit 20', reload WITHOUT realizing they have just double charged. 40gr of 5744 in a 50 cal bore is how long? 3/4"? - would a novice notice this?
I think I kind of stated this previously, sorry for repeating.
I think the double loader is too easy an answer (read my #3 from yesterday if you doubt it) and I will agree it can occur.
Thank you all for your thoughts and patience.
