I made an all Galaxy beer a few months ago that was pretty hoppy.
I based the grain bill off of the Row 2 Hill 56 clone thread on here; adjust for your sytem/gravity preference:
OG - 1.045
FG - 1.012
ABV 4.3%
6 gallons to the fermenter
6lb Pilsner
3lb Maris Otter
0.75lb Crystal 20
BIAB - heat 8 gallons of RO water with 2tsp Calcium Chloride, 1 tsp gypsum and 2.4mL lactic acid
Mash full volume at ~154
0.5 oz Galaxy FWH
0.5 oz Galaxy 10 min
0.5 oz Galaxy 5 min
1.5 oz Galaxy hop stand 30 minutes
Cool wort to 175
1 oz Galaxy hopstand 30 minutes
2 oz Galaxy dry hop in the keg when carbonated, chilled, and ready to serve; leave in keg until kicked
I fermented around 60F with White Labs 001
If you want IPA strength, get the OG over 1.060
