Anyone using BB .45 ACP +P 255 grain loads or equivalent ?

The Buffalo Bore website recommends increasing the recoil spring weight by 4-6 lbs over the stock spring......I'd like to try this load in my S&W 4506 and have a Wolff calibration spring pak that goes up to a 20 lb recoil spring ! I normally shoot standard 230 grain FMJ loads but want the ability to use +P loads . I figure I would have to change back to the stock 14lb recoil spring for the standard loads and use the heavier spring for +P loads or is there a middle ground ( say a 16 or 18 lb spring ) where both loads will work without damage to the pistol ? Yes , I'm new to setting up a semi auto .45 pistol so please help me out , thanks !
