Well, some information is better than no information, but Lucas changes up their oil's names and specs every season so it does create a little bit of confusion.
JASO MA rating no longer means very much as if you shoot for an MA2 and fail part of the test you "drop back" to only an MA rating. This is sad, but it is the way JASO rolls now-a-days. So an oil tested at 800ppm MA2 that fails part of the test gets an MA rating, which use to mean more ZDDP but
as of this year no longer means much of anything.
Some older Lucas data such as listed below shows the older MA/SL specs of 1100 ppm of ZDDP which would be a better oil than we have seen Lucas shipping sometimes currently under the MA2 listing (800 ppm ZDDP max).

Will your Savage blow up? Heck no, run the oil until you would normally change it. You can buy better oils for about half as much money, Rotella T6 comes to mind as a better full synthetic oil that happens to cost about $5 and some change a quart.
Running a 20w50 synthetic oil is not the best thing to do in a Savage. A decent synthetic does not thin out like an old Harley dino oil did in them old Harleys -- it stays full thick the whole time. And a 50W oil is too thick for normal use in a Savage, you will waste some gasoline and have extra sump oil temperature because the thicker oil can nether accept nor dump heat as quickly as a 40W synthetic can do. A synthetic 40w is the best all round use oil in the Savage engine.
You don't own a Harley, so why are you using Harley oil? You can, some do -- but it isn't what is recommended for a closer tolerance Japanese engine.
