Lil Gun I have found to be more forgiving and seems to work better with mid to heavier bullets.
That could just be an idiosyncrasy of your guns specs ammo included . As soon as you go to a heavier bullet you change the potential chamber pressures (
( force needed to move the bullet ) so the pressure curve is changed compared to what happens with a lighter bullet and you usually use a lesser powder load than with lighter bullets . So the phenomenon can happen using exactly the same powder in each case and those effects can also change from one gun to another and you can't compare different cartridges . Hodgdon never ever made any powder . He started in a caravan in a big paddock surrounded by drums of powder he bought from the manufacturers at wholesale prices . If Hodgdon was rebranding a ball powder in those days it's odds on it was Winchester powder .
We tend to think that the things that we experience in our equipment is the norm for everyone and that is just not the case . For an example a guy at my range has a 243 that is having extraction problems from pressure a full 4 grains under my load with no problems with the same powder .
I suspect it was a combination of things working together like, small case volume , tight chamber specs , tight bore , dirty fouled bore , hard projectiles .
