Yes you can shoot it, but it will be only in the silhouette (heavy rifle) class, you could maybe try hunter class,
Hunter class; it has to look like a hunter rifle, not exeed 8.5 Lb with the sights, barell not longer than 26 inches,
for the heavy class enything goes (almost) as long is not heavier than 10 Lb 2 oz, including sights.
Drop me an email and let me know where from Man. are you, maybe we will find a club near you
