20PPC w/55gr Berger.... thoughts?

[AlbertaAl]

My 12 year old SAKO AI HB single shot 20PPC needs rebarreling.

Intended to build a 20BR to shoot my stock pile of 55gr Bergers but since this SAKO needs a replacement barrel then I thought to explore the possibility of a 20PPC shooting 55gr Bergers

The barrel length would be 24 inch
The accuracy and bullet performance isn't being questioned, just wondering where the velocities might result. Can I get 3550/3600 or more ?

Past performance of this rifle 20Cal x 35 or 40 gr Bergers was limited to 450 yards on coyotes with clean kills. The old Hdy 33 gr. bullet was awesome.
