While Rocketman may have a different take on this, I've used his scale in general and find it to be 90% accurate, a great rule of thumb.
For me, this is my own math:
12 gauge = Par value
10 gauge = 70% of par
16 gauge = 150% of par
20 gauge = 150% to 200% of par
28 gauge = 200% to 400% of par (subject to make and being built on subgauge sized action)
.410 bore= 200% to 400% of par (subject to make and being built on subgauge sized action)
24 gauge = Par value (same value as a 12 bore)
8 gauge = Must be calculated independently on a case by case basis.
4 gauge = same scenario as 8 gauge.
