First year to hunt with the waters , can't make up my mind on 120 gr or 140 gr. I have had such good performance with the ballistic tips that I wanted to stay with them , so 120 and 140 are the two they offer, sos I called noslers bullet line [ toll free] they were more than happy to talk and offer any suggestions , I have found in the past they are always happy to help , what surprised me was his definite choice on the 140 gr. over the 120 . what might have influenced this was the fact that I started out by saying I was afraid the 140 gr. was maybe made more for the velocity of the 7mm mag. and that it wouldn't expand at the waters speed. he said definitly not and that the 140 would expand down to 1700 fps. and still liked the 140 over the 120. What else that makes me question this is the proformance of the 6.5 JDJ with 120 bt which has very similar ballistics as the waters has taken everything from plains animals in africa to whitetails - maybe we could get some ideas here on the best bullet for deer in the 7-30 I no the seirra 130 is out there but like I said I'm stuck on the ballistic tips.
