There is a reason the .30-.30 cartridge is still in production after all these years. Because, within it's limitations, (Deer etc. within effective range) IT WORKS.

If it ain't broke don't fix it has never been more true. I own two marlin .30-.30 rifles with the tasco scope you are mentioning. It was a combo offered in the late 80's I think.

Both are on "semi-temporary loan" to my nephews. both have taken deer the last three years with them and love them so much, I may forget to ask for them back.

Just be sure of you shot placement and enjoy!
