Nice looking rifle!
RL15 works great in my .303 British Ruger #1 with both the Woodleigh 215 grain RNSN and the Hornady 174 grain RNSP.
Its hard not to like a classy rifle in an easy to shot caliber that can be used to cleanly take 95% of the game we hunt all over the earth.
Thanks for posting. Looking forward to seeing photos of your adventures with this rifle.
