Instead of press fitting, why not heat the cylinder up in the oven to about 175 degrees. Throw the sleeve in the freezer for a while and then just drop it in the hot cylinder.
Then finish bore the sleeve in the cylinder.
1.250 dia. means about .0015 oversize sleeve/press fit.
It could save any damage to the sleeve, when pressing it in with force.
Thin walled stainless shrinks a lot when frozen.

Done a lot of bearings, bushings, gears of all types of material over the years and I prefer the easy way.
Just don't get things too hot.

Liquid Nitrogen is really fun to play with by the way.

Just my $.02 cents worth.
