What the differences mean
At the 7-iron, the RAZR X Muscleback is 35° and the RAZR X Tour is 33°, a 2° gap. Each degree of loft is worth roughly 3 to 4 yards of carry at the same swing speed, so the RAZR X Tour should carry roughly 6 to 8 yards further with that club, on a slightly lower, shallower flight than the RAZR X Muscleback. Across the 8 clubs both sets share, the RAZR X Tour averages 1.6° stronger, with the largest gap at the 6-iron (31° vs 29°). The pitching wedges are 47° and 45°; the stronger one leaves a 5° jump to a 50° gap wedge, which matters when planning wedge gapping.
The sets are built differently: the RAZR X Muscleback runs 2-iron to PW (9 clubs), the RAZR X Tour 3-iron to AW (9 clubs).
The RAZR X Muscleback is a blade iron and the RAZR X Tour a players iron, so they sit one step apart on the forgiveness scale. The RAZR X Tour is the more forgiving design, with a wider sole, more offset and more perimeter weighting for roughly scratch to 10 handicaps. The RAZR X Muscleback trades some of that for a more compact head, thinner topline and more control over flight and shape, which suits low single-digit handicaps who strike the ball consistently.
The RAZR X Muscleback is listed as forged and the RAZR X Tour as investment cast. Forging, as in the RAZR X Muscleback, is generally credited with a softer feel; casting, as in the RAZR X Tour, allows more complex cavity and weighting shapes, which is why it dominates forgiving irons.
Both sets were introduced in 2011, so this is a choice between two models from the same lineup rather than an upgrade: Callaway designed them to sit side by side for different players.
Which should you choose?
The RAZR X Tour is the stronger-lofted set — up to 2° stronger than the RAZR X Muscleback on matching clubs. Expect longer carry per numbered iron but a flatter descent angle; gapping at the wedge end is where that shows up.
