Brand new to the forum and happy to be a part. My son is 6 and loves to shoot his 243. He also LOVES to blast milk jugs with his 243. We recently tried a 100 gr Partition as I was thinking of using them for deer hunting this year. I worked up a load and we tried it out of his rem 700 compact. The load produced 2800 fps and had excellent results. We had jugs lined up on a board. The bullet penetrated the 6th jug!!! This was the best results we have had yet in terms of penetration, weight retention and mushroom. The mushroom was perfect and the weight retention was 72%. We had already tried sierra, hornady and factory winchester. None of them could beat the Partition!!
