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

I think it would gall in the 3500-3600 range for speed.
I would keep the freebore short and go 9 twist. |

After posting this I realized myself that staying with the 20BR is best !
I have the original factory 6PPC barrel and will just put that back onto this SAKO AI |

Over 3500 is hot for a 20BR with 55s in a 26". The 20PPC is not going to get there.

Perhaps a 20 Dasher would have enough case capacity to get there?
