I have been loading .223 for awhile. I have a Savage 16FHSS. I have been shooting 45gr,50gr and 55gr bullets. I see in Lyman's that they show loads up to 80gr. The rest of my books stop at about 60 gr bullets. Would the 70,72 and 80 grain bullets hurt the rifle. I was also wondering if the 80's would be enough for the smaller coast range deer. I checked with the regs and it is legal. Is it unwise? Thanks
