Boxton, Try and get hold of a couple of boxes of factory Norma 140 grain, which uses the Nosler ballistic tip. That will show you if you're getting the knockdown terminal performance you want. Around 300m the 7mm08 is dropping off in velocity, specially from a short 18" barrrel, so it won't be magic. I found I could get a bit better accuracy when handloading (30mm compared to 40mm at 100m) ) but that largely depends on how much you pay for equipment.
