Gonna go with SW Tactical and SW Match loads first. I have a bunch of 123gr HPBT already loaded using Match powder to fire-form my new Starline cases first then will start with load workups. I measured all of my magazines inside and they all are 2.330" so I can go longer COAL if I want, which I probably will eventually.
Gonna start with 29.12gr max with Tactical and 31.26gr max with Match. Gonna go 10% down from those maxs to start load developement.
QL shows velocities at max load of 2684fps with Tactical and 2781fps with Match. I imagine those velocities might be a a little high for a 20" but we will see. In GRT the load for Tactical was 28.62gr(.5gr less than QL) and for Match was 30.90gr(.36gr less than QL).
Load specs:
20" barrel
2.260" COAL
35.6gr case capacity-Starline brass
1.510" case length
70 deg temps
Disclaimer:
Do not use any loads from QuickLoad or Gordons Reloading Tool software that I post as they may be dangerous. The loads I am posting are worked up with QL or GRT for my bolt guns only and have not been tested by me yet or any pressure testing authority.
