No you dont need it. Water based so pretty much the next time you go to swab it out you will find that it had been rusting your bore while you figured it was protecting it.
Rem oil with teflon is a great oil to use in your bore. Swab the bore with a damp patch, allow to set for a few minutes and then use a dry patch to mop up the excess oil.
I don't know if it is absolutely necessary but I use it in my Triumph and every other gun I own every time I clean them. Have used it for years and like it
It's not needed, but it's not water based either. It's made with mineral oilandparaffin waxes. People like it because it stays put and clings to the walls of the bore without running down into the breech.
By itself, itdoesn't promote rust. But humidity and residual powder foulingmight if the gun isn't thoroughly cleanedand preserved in the first place.
For me, it's anything but bore butter. I use any light gun oil I have around, or plain old 3-in-1 oil. Rem-oil is excellent.

If you want to use bore butter in your rifle.. go right ahead. Its your rifle. All I will say is there is not place for it in my rifles. My wastebasket yes, my rifles no.

Bore Butter is not made for inlines, don't use it in them...Regular gun oil is what is best for an inline...
Bore Butter was developed for side hammer guns, they marketed it as a product that would "season" the bore and
give you many shots between cleaning...Most of us didn't buy it...We realized that while you can season a cast iron
fry pan, gun barrelsare made of steel...

actually that is not entirely true. Stainless steel maybe, depending on the type of alloys and percentage , but carbon steel does need seasoned just like cast iron. Do a little research on steels and see , Try wikipedia or even google
