reloading 8 gauge

[james12345]

Hi everyone, looking for some tips on loading for 8 gauge. The gun is a Ralph Grant 8 gauge, a bored out Spanish 10 gauge. From what I can figure out the bore is .815", tight for an 8. I have Remington industrial hulls and I was going to go with fibre wads, as I read the plastic ones could be too tight. Any suggestions for powder, I am currently using IMR 700 in my 12 gauge loads.

No data around due to it being illegal to hunt with anything bigger than 10 guage. I sure wouldn't trust a bored out Spanish shotgun either. However, try a net search for 8 bore vs 8 guage.
