The 40x is not a rebranded 721/722. Back in those days as far as rimfires the 40x had a straight bolt handle like the 721/2 and the 40xb had a swept back 700 style handle. The 40x no matter how much they cost from the "custom shop" is no different than a solid bottom 700. They need trued just as much as any remington. They were nothing magical at all and had the same tolerances.
