Picked up a box of sierra match kings at angeles the other day. The box says for 1-7 to 1-8 twist barrels. My 243 is a 1-9.25 twist, should i bother trying these or just wait until i get a new barrel?

107gr will be too heavy/long for your barrel.
I use the 107s in a 6mmBR with a 1:8" twist.
Mid 90s are about as heavy as you want to go.
