As Mike pointed out already, 80 grains is very close to the original 5 or 5,1 grams.
Switching to a lead-free bullet is in my eyes the worst thing one can do here, no gains except "lead-free", but potentially opening up several new cans of worms (besides finding the mentioned brands in the US).

Raimey, your reloads are looking good so far, no need to explore the limits.
