In two words, not much...

Now, mine has a wooden stock...I also free floated the barrel...I got caught in a rain storm one day and the gun got soaked...I pulled the barrel and letthe stockdry for a few days and the point of impact had changed...That's when I free floated the barrel and had it pillar bedded...

I wanted to try different factory ammo...That was the reason that I had a new barrel put in it a few years later, but the gun was about 20 years old at the time and I do shoot much more than most guys...The dang gun just loves CoreLokts, it liked them before the work and still likes them...After killing several deer with about 10 different factory ammo bullets I found that the CoreLokts work as well as any so that's what I stuck with...

With your's being a synthetic stock, this shouldn't be a problem...

My brother also has a .270, tang safety, wood stock as well...I do his work on his guns...I gave it a good cleaning and adjusted the trigger myself, it shoots good with the Federal Premium 130gr Sierra GameKings...I never free floated his...

I like a trigger about 2 1/2 - 3 pounds...I have heard the 3 position safety models can be adjusted by a good gunsmith and have had others say, just drop in a Timney and be done with it...

I'm not sure of the quality of the Ruger synthetic stocks...You might consider putting a McMillan or other higher quality stock with the aluminum bedding in it....

How well does the gun shoot now?? Have you tried several different brands of ammo???

We all want guns that will put every bullet into a dime at 100 yards, but frankly a 1 1/2 inch group at 100 with the right factory ammo will kill deer all day long...You can spend a bunch of money trying to shave off a half of an inch from a group...I know, I sure did...
