Thanks for reaching out JD! This ammo is loaded to standard pressure, and projectile type would not impact recoil energy. Objective recoil energy is determined by four factors: handgun weight, propellant weight, muzzle velocity and bullet weight. That said, certain types of propellant burn at different rates, which means the initial impulse of recoil may be sharper if the propellant burns up faster right beginning right at the instant of ignition. There's no sugar coating it: Tula is cheap ammo, so my guess would be that the Russians used an inexpensive propellant that combusts very quickly instead of providing the slower, more even burn which distributes recoil energy more evenly throughout ignition. It should have no impact on performance or harm your revolver – you just get a stouter snap right off the bat. I hope that makes sense!
