Just like rifles have their special and specific flavor of pellet the they like best, it's the same with lubing or not.
I've experienced both scenarios. One rifle liked it and did better. Another one didn't like it at all. Still another one, It didn't make any difference either way.
Best to try it and find out.
Here's how I do it....
Take the foam out of an old pellet tin. Work a small amount of your flavor of lube into the foam. You don't want it sopping/dripping, that's way too much. Just enough to coat the foams all the way through so that if you mash them up as small as you can, you're not dripping. Put them back in the tin. Add a layer of pellets leaving enough room for them to roll around. Finally, gently shake the tin back and forth or roll it to get the pellets moving around. Now all those pellets will have a thin film of lube.
