The first sub bases to be used, by Toby Bridges I believe, were28 guage shotsell bases... and it is still recommended a lot by different shooters... With the new Polymere sabots that really contain pressure better than the older Plastic sabots have almost made sub-bases un-neccesary. That may be different story in the case of the Savage with smokeless powder.

I have a couple packages of sub-bases and have used maybe 10 of them - did not see any difference.

The 28 guage sub-base should not create a great of extra pressure unless you believe you are leaking pressure with your current sabots...
