There is no way to predict which bullets be be accurate in a specific gun.These bullets may have been the accuracy load in the manual but that does not mean they will be accurate in your gun.The only way to find out is to try them.I am hoping you are starting with a reduced load and working up watching for pressure signs as you go.To just pick a higher end load from a manual and load it is a foolish practise that could have very undesireable results.
