Almost every rifle in my house shoots some weight of a Remington Core-lokt very well, the only two rifles that don't care for it are both .243 winchester, and they love that Winchester "grey-box" 100 grainers. So in my load developement I used Sierra Gamekings in 100 grn, and Winchester Supreme 780, The rifle I developed this load for shoots them into a real small group at 100 yds.
