I have a Pro Varmint on my HB SS Bmag and it fit just fine, even before I had it bed.
Where did the stock crack? Just taking a stab in the dark here but I'll bet he didn't take the escutcheon pillars out of the old stock and put them in the new stock before he tightened it down.
Bmags are a little difficult to bed in a conventional manner. Most just bed the first few inches of the barrel and call it good. I guess that type of bedding works ok for them.
