Since the new rifle has already been bought & paid for by the raffle sponsors, I would keep the Winchester.
In recent reviews, the X-150 was rated higher than the ML or MLS. It's easier to clean, has less blowback with 209 primers than the ML has with musket caps. The X-150 shoulders easier & balances nicely.
Plenty of trigger problems associated with the ML/S and the awkward removal of the bolt described in the owners manual is a disgrace to this long-standing, once reputable company that has fallen on some major quality control concerns lately & their customer service appears to have succumbed to the same disease.
If you decide to keep the Remington & you are not removing the bolt to clean the action, there's a small section of it that's not being seen with the naked eye that will completely rust thru... causing a permanent failure of the rifle.
If the store offers you full credit on an exhange, for the same money, get the Knight Wolverine II 26" with the Timney trigger, Green Mountain barrel and the new red discs that help waterproof the action. If they only have the 22", most stores will order the 26" for you.. all you pay is the shipping. Then turn around & sell the ML on gunsamerica.com, ebay.... etc.
Here's a review on your Remington ML/S
