[QUOTE="RUMBALL, post: 752321, member: 53976"] Gday I use the 90gr sierra in my tikka t3 270 and at 3.200 oal it was getting rifling marks on projectile after using a oal gauge it was 2.275 at the orgive and my oal cartridge length was actualy3.183 on the lands. So I seated them at 3.170 oal had them loaded with 60gr of ar2209/h4350 and they are deadly accurate. Maybe different in your rifle so start a grain or two less this is not a max load but best to work up just to be safe. winchester brass,fed 210 primers. Also have used 110 vmax havnt spent much time with them last test was 54.5gr of 2209/h4350 this is mild load with 1/2 inch groups im sure they could be better with some work. Cheers Rumball. [/QUOTE]
