Help with new build

[trapperdan]

I have a Pac-Nor 20 caliber 7.5 twist barrel and a ton of 20 caliber 55 grain bullets along with a rem 700 action with 223 bolt face. What would be the best chambering for this combination if any? Thanks
Dan

If your stuck on 55gr, I would change out the bolt to accept a necked down 6br case

20 Practical or Tactical would be my vote.

I have a 20 Practical with a Bartlein 8-7.5 gain-twist barrel and it stabilizes them fine. While the 20 Practical might not send them down range the fastest, they are pretty accurate and fun to shoot in my rifle. Im using Benchmark powder and have them going 3350 out of a 26" barrel. Here's a video of a poke at the 750 yard gong.
