I have a scoped 303 and it had to be restocked to get my eye up to the scope. I went from a B-square mount which was rock solid but really high to a ATI mount, not has tall. Just put the ATI mount on and tried it out yesterday. It can shoot 2 inches at 100 all day if I do my part with the hold and the loads so far the ATI mount has held zero but has not taken the beating that B-square took. This rifle likes the flat base 150's but not boat tails? A scoped 303 should take deer to 150 yards no problem. I agree the 303 is a rimmed 300 Savage. I have both, recoil is about the same ballistics, Real close, Both are true Classic killers. Love taking my as issued NO1 Mk3 303 hunting I know it will work under ALL conditions plus I can sick the 15 inch byonet on the front to scare'em to death! I hate having old eyes it will suck not taking my Aussie No1 girlfreind with the big knife for a stalk in the woods. Oh well the plastic stocked scoped NO.4 will do just as good plus it's lighter.
