To each there own, but, if no accuracy/group, testing/shooting, has been done, one will never know if any reinforcement was needed.
I had the same reservations about my Hog Hunter stock, since day one. Then I tested for barrel harmonic disruption, and realized Savage knows what they are doing, and ended my fears. Even so, I still don't like the factory stock and I am still looking for a more substantial replacement. But, my preference has nothing to do with accuracy problems from the barrel touching the stock.
Now, I should specify that my Hog Hunter has a heavy/short profile barrel that may make it less susceptible to interference, but I doubt it. As stated, the flimsiness of the fore end couldn't interfere with groups from any contact with the barrel.
