No. FMJ is illegal in Washington. Considering all the other expenses incurred going on a hunt if you can afford to go you can afford a box of Remington Core Locked.

The the local club has about eight M-1s that they got from the DCM. Their condition is so good that they'd make a lot of you drool. Before we lost the lease on the outdoor range there was a monthly match in which you could bring your own rifle or shoot the club M-1s with FMJ that came from the CMP. It was an unrecorded casual "fun" match run like a real match except you could fire your scoped AR-15 varmint rifle or what ever you wanted. Technically the old Garands should not have had a chance but I always kicked butt with them. After they get up off the mat not too many guys can shoot worth a hoot.

I have my own as well. Being comfortable with M-1s helped.
