[QUOTE="Hand Skills, post: 1555497, member: 103303"] From a handloader's perspective, yes the 300win is capable of at least 100fps more. The 7WSM? I'm skeptical... Ammo manufacturers play a game where the newest cartridges get loaded to the fullest potential and older cartridges do not. Not all cartridges are rated to the same pressures. For example the 7mm RM has been derated by SAAMI from 65kpsi to 61kpsi. But the 7WSM is 65kpsi. The 300win is 64kpsi, but that 2850fps load is nowhere near it... 'Apples to apples' is a slippery slope. In fact I'll retract my previous suggestion of changing the data. Keep it 'apples to apples' with factory loads, it will be most useful this way! Yes, some cartridges do have 'more room' for improvement than others, and that's part of what makes reloading so fascinating! [/QUOTE]
