I have shot several deer in the last 3-4 years with a P14 303 British. My pet load for this job is a 180 grain Norma RNSP that I shoot at about 2450 fps. I have not taken any shots out further than 150 yards, but inside that, they are accurate and effective. Have not recovered one either, so cannot say what they look like after doing the "deed", but from looking at the exit holes, I have to say expansion is dependable and good, with exits being about Toonie size. No deer went more than 20 yards after the shot, all have been one shot kills. Regards, Eagleye.
