yup yup!!!!! But if you must switch, try the Rl 22 like Stubble said, I use it with my 7mm and it works great. If the 160 partitions dont work, try 160 accubonds, i am having real good luck with them. I personally have found the accubonds to group better than partitions, i dunno why but they do. I use 61 gr of Rl 22 and seat the bullet to 3.38 oal. hope this helps.
