I live in the NY where our fearless leader coumo has made mail order ammo illegal and I haven't been able to find any .303 wolf or anything cheap locally...
Have you tried talking to any of your LGS's to see if they could order ammo for you on a "cost plus X percent" basis? Even if you had to pay shipping plus an extra 10 or 15 percent, you should be able to get good reloadable.303 ammo for less than $20 a box if you buy in quantity.

If you do decide to reload, I highly recommend the Hornady 174 grain round nose .312 bullet.
It's easy to work up accurate loads with this bullet, even when your rifle has some throat erosion or a less than perfect bore.
It has a poor ballistic coefficient, but kills well at short to medium range.
It seems like boattails are a lot harder to get good accuracy with. The 174 grain Sierra MatchKing's don't shoot as accurately as the cheap RN Hornady bullets in most of the .303 rifles I've loaded for.
I have a bunch of pulled .311", 7.62x54R, 147 grain Czech steel core boattails that I bought cheap years ago. They shoot OK out of my PSL, but print patterns rather than groups out of the .303's I've loaded them for.
Cheap Hornady Z-Max bullets shoot pretty well even though they're only .310" in diameter, but I wouldn't use them for hunting anything bigger than a coyote, especially at .303 velocities.
