[QUOTE="elkaholic, post: 379608, member: 13833"] The reason the bullets seated the same is because they are both an 8s spitzer design so the ogive is the same. The difference in the two is the shank length that contacts the lands. You are correct in assuming that best case scenario is to seat the longer bullets to the base of the neck for more case capacity and sometimes better accuracy. I should have been more clear why I was pumping to see exactly what bullet you planned on sticking with. It seems you are not quite sure at this point so I would in that case go with the 10 twist (as Mark suggested) and I would have it throated to accomodate the A-MAX or what ever is the longest you decide on. Be aware that if you do that, the 165's may barely go into the neck if you want them near the lands which "usually" equates to better accuracy. This is why you need some idea of what you want to accomplish in the long run. Also be aware that you can always cut the throat out a little further but you can't put it back if you cut too much unless you set the barrel back. Hope this helps......Rich:D [/QUOTE]
